Your Complete Guide to DSG Gearboxes

For decades, automatic transmissions have been viewed as the antithesis of performance by most automotive enthusiasts. Power-sapping torque converters, glacially slow shifting, and driver feedback described as vague at best, are some of the key complaints about older 'traditional' automatics. With the DSG transmission, a dual-clutch automatic, Volkswagen and Audi revolutionized the industry, providing an efficient option that offers reliability and race car-like performance for the masses.

What Is A DSG Transmission, And How Does It Work?

DSG is the Volkswagen marketing acronym for their family of dual-clutch transmissions or DCT. DSG stands for "Direkt-Schalt-Getriebe," or direct-shift gearbox. The VW DSG transmission is similar to all other common DCT designs in that it is effectively two separate electronically controlled manual transmissions built into one.

The DSG combines the best attributes and efficiency of a standard manual transmission and the ease of use of a more traditional automatic. DSG transmissions can be operated in a fully automatic mode, where the computer decides when and how to shift, or in a semi-automatic mode, where the driver uses either the gearshift shift lever or steering wheel-mounted paddles to select the desired gear. DSG and DCT transmissions have been a game-changer in the automotive world and in performance circles. Rarely has one component been able to increase both efficiency and performance with almost no downside.

DSG Technical Drawing

All Volkswagen DSG transmissions are a transaxle design, which means that the same transmission case houses both the gears, the final drive, and differential in one unit, with shared oiling and lubrication. Much like a standard manual transmission, a DSG-equipped vehicle has a flywheel, which mates to the input shaft of the transmission, and is engaged by a clutch. This transfers power from the engine, through the transmission, and finally to the drive wheels.

DSG Input Shaft

As you would expect by the name "dual-clutch transmission," the DSG has two clutch packs, as well as two separate input shafts. Both are a concentric design, which means that one fits over the top of the other. The first clutch pack engages the odd gears of 1, 3, and 5, while the other engages the even gears of 2, 4, and 6. The two clutch packs are designated as K1 and K2.

The clutches in most DSG transmissions are a 'wet clutch' design, which means that the plates and friction rings are lubricated and cooled with transmission fluid, actuated via hydraulic pressure generated by a mechanical oil pump, and applied by the Transmission Control Unit (TCU). VW calls this the Mechatronic unit, and it is the brain behind the brilliance of the DSG transmission.

VW DSG Mechatronic

Since the Mechatronic unit effectively has two transmissions to work with, it is able to pre-select the next gear that you need before engaging the clutch and performing the shift. It simultaneously disengages one gear as it engages the next, resulting in that perfect power delivery. Where the DSG shines is in its ability to deliver both smooth and lightning-fast shifts, no matter the situation. From loafing along in commuter traffic to hitting back roads or race tracks on the weekend, it can do it all.

Connected via the vehicle's computer CAN bus system, the Mechatronic works in conjunction with other control units such as the ECU (Engine Control Unit) and the ABS braking system. It has a variety of inputs to decide how and when to shift, such as vehicle speed, engine speed, throttle position, brake pressure, and g-force measurements from the accelerometers in the car. The Mechatronic unit can guess with remarkable accuracy which gear you're going to want next, whether you are accelerating, braking, or cornering. It also knows how hard and fast to make the shift, and if it should upshift or downshift, using the same sensors and parameters.

DSG Power Delivery

For example, if you're just easing along in traffic and not accelerating or braking with a lot of force, the transmission will work its way up or down through the gears easily, ensuring smooth performance and shifting at low revs to maximize fuel efficiency. A DSG-equipped vehicle driven gently will use less fuel than the same car equipped with a manual.

However, if you press the accelerator pedal down like when you merge onto a busy highway, the Mechatronic unit sees the increased power produced by the engine and holds the gear longer, or performs a down-shift depending on the current gear and RPM, ensuring faster acceleration. It also will make the shift to the next gear more quickly, with a faster and more abrupt engagement of the clutch. A DSG transmission can perform a complete shift in around 200 milliseconds and can shift more quickly than the best drivers in a similar manual transmission vehicle.

How much faster? Depending on the exact trim level, the DSG equipped Mk7 GTI is about two-tenths of a second faster to 100 Kilometers per hour at 5.8 seconds on average, compared to 6.0 seconds for the manual. Similarly, it is about two-tenths of a second faster in the quarter-mile, averaging 14.3 seconds over 14.5 for the manual transmission Mk7 GTI.

Most DSG-equipped models also feature a 'Sport' mode in addition to 'drive' or 'manual' modes. Sport mode changes the programming to be a bit more aggressive and not as focused on maximum efficiency and fuel economy. The result is that it shifts faster, holds gears longer, downshifts to make use of engine-braking, and is generally more responsive for sporty driving. On many vehicles, Sport mode may also change the responsiveness or power of the engine, firmness of the suspension, or make other changes to enhance the driving experience.

There is one side-effect of the fast-shifting on DSG-equipped vehicles, which people tend to either love or hate. The "DSG Fart," as it's known in most enthusiast circles, is a loud 'crack' from the exhaust which occurs in between shifts on hard acceleration.

Although this is fairly muffled on factory vehicles, the more free-flowing the exhaust, the more likely you are to hear it. The sound itself is the result of the engine computer pulling timing from the ignition cycle when the shift occurs; This allows the engine RPMs to fall appropriately, the shift to occur, and for the next gear to be engaged smoothly. A small amount of unburned fuel passes into the exhaust on this process and ignites, creating this sound. This timing cut is the same reason you hear a loud pop on upshifts from race cars equipped with sequential or DCT transmissions.

For those of us who like to imagine we're driving a race car while we're running errands or commuting to work, it can add some fun to an otherwise dull drive. Some of the newer cars from Volkswagen and Audi tend not to do this as easily as early models thanks to changes in transmission design, engine specification, and programming. Regardless, if the idea of a flatulent car puts you off a bit, not to worry. If you don't modify the exhaust system from the factory specification, it will rarely, if ever, be audible.

History Of The DSG Transmission


The Volkswagen DSG, as we know it, debuted in the first-generation Type 8N PQ34 Audi TT, in the 2004 TT 3.2 Quattro. Volkswagen didn't provide the DSG as an option for their own vehicles until mid-2005, in the then-new Type 1K PQ35 Mk5 Jetta TDI. The DSG is a perfect match for a torquey turbo diesel engine and has been the go-to automatic option on most VW or Audi TDI cars since.

MK5 Jetta DSG

In 2006, the full Mk5 line up launched and added the DSG transmission as an option on the sporty GTI 2.0t 2.0t versions of the Golf and Jetta.

A vehicle equipped with a DSG transmission will have a traditional automatic-style gear selector with a 'PRND' indicator. Most but not all models will have "DSG" or "S Tronic" branding on the gear selector.

Volkswagen and Audi have typically used DSG and S Tronic DCT transmissions in their more sporty models, such as GTI, CC, and select R models from VW, most S and RS models from Audi, and nearly all TDI-powered vehicles from 2006 on. There are some models that gained or lost a DCT option depending on the year and model options, so be sure to double-check if you're looking to purchase a car and are unsure if it is equipped with a DSG or S Tronic transmission.

What Is The Difference Between VW DSG, Audi S Tronic, BMW DCT, And Porsche PDK?

Fundamentally, there are no major differences between the dual-clutch transmissions offered by the various German auto manufacturers.

Porsche 991 911 GT3 3.8
Porsche 991 911 GT3 3.8

Porsche wins the award for the hardest to pronounce name with "Porsche-Doppelkupplungsgetriebe" (Porsche double-clutch transmission), which is what PDK actually stands for. PDK operates in the same fashion as all other dual-clutch transmissions but is known to be one of the most refined and best-performing DCTs on the market. Similar to VW and Audi designs, PDK transmissions are all transaxle designs. Porsche is notable for having developed a PDK transmission for racing use back in the early-1980s as part of their 956 / 962 Group C program. The PDK didn't prove to be reliable enough at the time but has since been used in a variety of the entry-level Cayman GT4 machines from Porsche. Similarly, Volkswagen DSG and Audi S Tronic are both used on factory-built race cars, including our own Volkswagen GTI TCRs.

Audi S Tronic

S Tronic is simply Audi's marketing term for DCT-equipped vehicles. Audi's S Tronic and Volkswagen's DSG are identical in transverse powertrain vehicles, such as the Audi TT, TTS, TT RS, A3, S3, and RS3. Audi's more sporty longitudinal powertrain vehicles such as the S4 3.0t, S5 3.0t, RS5, and S6 4.0t are also offered with S Tronic transmissions.

BMW DCT differs only in that it is not a transaxle design like those from VW, Audi, and Porsche, but operates on the same principles and with the same primary components. BMW models have the final drive and differential divorced from the clutches, gear set, and fluids. The BMW DCT transmission is only offered on rear-wheel-drive models in the BMW lineup and is not an option on any of the xDrive variants. The BWM DCT transmission is primarily offered on performance models such as the M-badged cars and has received similar accolades to Porsche's PDK for being one of the most responsive DCT transmissions on the market.

DSG Transmission Specifications, Details, & Codes


VW Jetta TDI Cup DSG

The first production iteration of the DSG transmission, the DQ250, is a 6-speed transverse design utilized in a wide range of vehicles in the Volkswagen Audi Group. Exact specifications such as gear ratios and final drive will vary depending on the exact transmission code, but the design, function, and core components are all very similar. As technology has improved, the Mechatronic unit has been upgraded and improved, so the newest examples can shift faster, smoother, and are typically less likely to experience Mechatronic problems. The all-wheel-drive 4MOTION and Quattro DSG or S Tronic equipped DQ250 variants utilize an outboard transfer case design, and are otherwise the same as the FWD examples.

The DQ250 is the most commonly used DSG design. With factory Mechatronic programming, it's rated to handle up to 399Nm of torque.


Audi 8S TT RS 2.5t Evo S Tronic DQ500
Audi 8S TT RS 2.5t Evo S Tronic DQ500

The DQ500 is the first 7-speed transverse design sold in the Australia by Audi, and also utilizes a wet clutch design like the DQ250. It was originally used in VW Transporters and other more industrial designs in Europe, which require high-torque handling, but has been adapted for use in the ultra-high performance Audi TT RS and Audi RS3 2.5T. With factory Mechatronic programming, the DQ500 is rated for up to 599Nm of torque.



The newest transverse offering is the 7-speed DQ381, as introduced in the 2018 VW Golf R and 2019 VW GTI. It shares much of its design with the DQ500 and is rated for up to 429Nm of torque with factory Mechatronic programming. Both the DQ500 and DQ381 transmissions offer even better fuel efficiency potential than the DQ250 with the addition of the seventh forward gear, along with their increased torque capacity.


Audi introduced the longitudinal DL501 7-speed S Tronic transmission in a variety of their more performance-minded sedans and CUVs such as the S4, S5, and S6. The DL501 differs from all of the transverse type DQ transmissions in that it has divorced lubrication systems. The oil for the gearing and differentials is separate from the oil, which is utilized by the clutches, Mechatronic unit, and pump. This should, in theory, provide longer life and more reliability as there is no cross-contamination of fluids or particles between the two separated sections.


Audi R8 5.2 V10 Plus S Tronic
Audi R8 5.2 V10 Plus S Tronic

The R8, Audi's top-line sports car, received an S Tronic gearbox option in 2012 with the introduction of the 5.2 V10 engine. The DL800 is a 7-speed DCT transmission, utilized only in the Audi R8 and sister model from Lamborghini, the Huracan. This same street-derived S Tronic transmission is used without any internal changes in the R8 GT4 race car, lending further credibility to both the performance and reliability of the VW / Audi DCT transmission family.

Common Problems Of The DSG Transmission

For the vast majority of owners, Volkswagen DSG transmissions have proved to be remarkably reliable. Though, like any other type of transmission, they are not without flaws and occasional issues. With proper service and maintenance utilizing high-quality parts and fluids, however, a DSG transmission will provide years and many thousands of kms of reliable performance. As they have been developed and updated over the years, the DSG-family has only become more reliable.

Rough Or Hard Shifting

The most frequent complaint from most DSG owners is clunky or hard shifting in certain conditions or at certain throttle positions. While this can be indicative of a transmission problem, accessory components such as engine and transmission mounts should be checked and ruled out before looking for more significant problems. Likewise, the driveline components such as CV axles and wheel bearings should be checked and confirmed as good, as they can also result in other noises and vibrations if they are worn and need replacement. This complaint is more often levelled at the transverse DQ250 models rather than the newest DQ500 or DQ381, or longitudinal DL501.

If you are used to driving a manual transmission vehicle, you will find that a more direct, decisive driving style will help to avoid clunks and provide the smoothest driving experience. Despite the speed with which the DSG can go from gear to gear, inconsistent throttle application or too many inputs in quick succession can 'confuse' the Mechatronic unit and result in some of the common driveability complaints. Essentially, the Mechatronic unit is always trying to guess which gear you will need next, whether that is one up or one down from where you currently are. Because it can only do that so quickly, that shift may seem less smooth or more sudden, or slower, than what you normally experience—this is not a problem, merely a quirk of the system and how it works. Performance tuning, which we will dive into later, can help to rectify this issue even when it comes to normal driving situations and result in smoother and better DSG drivability.

Flywheel Failure

In terms of real problems, failure of the dual-mass flywheel is probably the most common wear-related issue on DSG vehicles. Signs of a flywheel issue include failure to engage gears from a stop, slow or hard shifting, and in the most extreme cases, RPM-dependent vibration and audible noise. Due to the vibration of the diesel engine, TDI models are most commonly affected by flywheel failure, with replacement often needed around 169,000 to 228,000 kms.

Petrol engines typically can go much longer on mileage before requiring flywheel replacement, but results can vary depending on use. Worst-case scenario, failure to replace a bad flywheel can result in damage to the bellhousing and parts of the transmission, so it is best to stop driving if you suspect a flywheel issue until you can diagnose and repair it. After replacement, proper adaptation and recalibration of the clutches are required for the best performance and return of smooth shifting.

Mechatronic Unit Failure

Although it's not a widespread issue, the most serious and typically most expensive problem that can arise on a DSG transmission is a failure of the Mechatronic unit itself. Failures can result in a number of issues, ranging from hard or jerky shifting, failure to shift or engage from a stop, or complete and total transmission malfunction. In this instance, the transmission goes into a 'limp mode' with a limited number of gears available for use, or it may completely disengage the clutches to avoid damage, even while driving. Proper diagnosis with an electronic scan tool is the best and most accurate way to begin the process of determining if there is a Mechatronic fault. Even in the instance of total Mechatronic failure, the physical transmission itself, such as the gears, clutches, and differential, is typically not damaged in any way.

There have been recalls on a few DSG and S Tronic transmissions. Select examples of DSG-equipped VW models built between September of 2008 and August of 2009 were manufactured with a bad batch of Mechatronic units. The fault is specifically with the transmission temperature sensor, which was prone to failure. The result ranged from a fault on the dashboard, to the transmission automatically going into neutral even when 'drive' or 'reverse' is selected. Any vehicles in the affected range should have been repaired by now, but if not, an open recall repair should be able to be performed by a Volkswagen dealer. Although they were not included in the recall, the 2008 VW Mk5 R32 also featured a higher number of similar Mechatronic failures at that time.

DSG Transmission Clutch Pack Wear

The clutch packs themselves can eventually wear and require replacement; This is fairly atypical and is usually the result of an underfilled transmission, failure to service the transmission fluid regularly, or extremely modified engines and heavy use such as drag racing. With factory power levels and programming, it is unlikely that the clutches will ever need to be replaced if the car is serviced properly. One significant benefit of a wet clutch is that it is tough to overheat them, and they are generally very long-wearing thanks to the lubrication of the hydraulic fluid.

Common Maintenance On DSG Transmissions

Fluid & Filter Service

The most important service to perform on any dual-clutch transmission is to keep the fluid and filters replaced on schedule, with the best quality parts. Exact service intervals will vary depending on the exact vehicle year, model, and transmission code. Performance models such as the 8J TTS have a slightly shorter service interval from the factory than other models that use the same basic transmission. If you have a heavy foot, have a highly modified car, or drive your car on the track, you may want to consider shortening the service interval as preventative maintenance.

If you are driving your DSG-equipped vehicle on track days or in situations with extreme temperatures, it is possible for oil to be pushed out of the overflow vent located on the top front of the transmission case. This is rare and may be a side-effect of a slightly overfilled transmission. Although this is typically a very small amount of fluid, if it occurs with a decent amount of regularity or you're attending a lot of track days, it is worth checking the fluid level in between events to ensure you are not running the system low on oil. There are a handful of aftermarket DSG cooling solutions to help eliminate or mitigate this.

Outside of the fluid service, DSG transmissions don't have any other regular maintenance requirements. Clutches and flywheels are service-free as long as they are functioning correctly and will benefit from regular fluid changes. Related components such as engine and transmission mounts, should be checked and replaced as needed, as well as the CV drive axles.

DSG Transmission Oil Service Information

Performing a transmission oil service on a DSG transmission is the most important thing to ensure maximum life and maximum performance. If your vehicle is new to you, is within the DSG service km window, and has unknown service history, you should always perform a DSG transmission oil service to ensure it is up to date.

DSG Transmission Oil Service Interval

Every vehicle from Volkswagen or Audi will include a recommended service interval in the owner's manual. On the vast majority of models, a DSG transmission oil service is required every 60,000 km. Audi specifies a slightly shorter interval of 50,000 km on older transverse models such as the 8J TTS and Audi A3. Conversely, Some of the newest models from Volkswagen equipped with the front-wheel-drive DQ381 are now specifying an 120,000-kmservice.

Although it isn't specifically mentioned by Volkswagen or Audi, a vehicle experiencing extremely heavy use such as on-track performance driving, competitive racing, or towing, may benefit from a slightly shorter change interval. Based on past experiences, continuing to abide by a 40,000-km service interval even on the DQ381 transmission will likely provide the longest life from the gears, clutches, and Mechatronic unit. It's inexpensive insurance on such an expensive driveline component.

If your DSG transmission is experiencing slipping, hard shifting, or other drivability issues, a transmission service could help to rectify these problems. A DSG transmission that is low on fluid will not function properly, and continuing to drive a transmission that is low on oil may result in damage to the clutches, gear sets, or other internal components.

What Fluid And How Much Does The DSG Transmission Require?

Most DSG transmission services will require an approved DCT transmission fluid, transmission oil filter, sealing o-rings for the filter and housing, and a drain plug gasket. The longitudinal DL501 is equipped with a second, non-serviceable internal oil filter or screen which does not need to be changed during a normal service. The only time to replace or clean the internal filter would be if there is known internal damage or a large amount of metal is present in the DCT transmission oil. The transmission pan has to be dropped to perform the service and will require additional gaskets and seals.

The transverse DQ250 requires somewhere between four and five liters of DCT oil to perform a transmission service. The larger longitudinal DL501 typically requires between seven and eight liters of DCT fluid. These two fluids are not necessarily interchangeable.

DSG Transmission Performance Upgrades

The DSG transmission has absolutely changed the landscape of performance tuning options for VW and Audi vehicles. Out of the box, they are strong, reliable, and offer nearly uninterrupted power delivery. With performance tuning of the Mechatronic unit, a whole new world of possibilities is opened up.

DSG/Mechatronic Tunes

A performance tune on a DSG transmission typically offers a few standard improvements of the factory programming.

First, the shift points and logic behind how and when, and how hard the transmission goes through the gears, is optimized more for performance, response, and acceleration rather than pure fuel economy. This usually results in better overall drivability and a more rewarding driving experience, as the car no longer seems eager to simply get to top gear as quickly as it can and loaf around at 1,200rpm. This translates into more fun behind the wheel with daily driving or with a spirited run on a back road. Smaller changes, such as reduced pull-away delay, gear selection displayed in the gauge cluster, and faster response from paddle-shift input, further improve the driving experience.

Drivability is especially improved for vehicles that have had some kind of ECU upgrade or performance tune installed. When an engine is making more power and the TCU is not remapped for managing the increased power and torque, all of the decisions made by the TCU are thrown off, and it may result in less desirable performance. For example, for a mild increase in engine power, this means that there may be an occasional hard shift, oddly chosen gear, or unexpected downshift depending upon the situation at hand.

Added to this, because the Mechatronic unit is constantly monitoring and managing engine power output, it has the ability to interfere with the amount of power that makes it to the ground. A performance DSG tune, even on stock programming, will usually result in noticeably improved power output and delivery characteristics.

Since virtually every aspect of a DSG transmission is computer-controlled, a performance tune can also increase the effective power handling of the transmission tremendously. A stock TCU matched to a highly modified engine may result in slipping clutches or even clutch damage. By fine-tuning not only the clutch pressures but also the timing and overlap of the gear changes, a performance tune can ensure near-standard clutch life even with much higher torque outputs. Although most software companies don't rate their DSG tunes with a specific number, it is generally accepted that a standard DQ250 with a performance tune can handle between 542-677Nm of torque on stock clutch packs depending on the tune. This is an increase of over 135-271Nm over the factory rating with no other changes.

Most performance tunes will also offer some kind of 'full manual mode' where the TCU doesn't downshift automatically in the same situations where it normally would. Anyone who has driven an automatic transmission equipped car can probably relate to the car downshifting aggressively when all you wanted was a tiny bit more passing power. A performance DSG tune improves or sometimes eliminates that depending on your drive mode and exact tune.

A performance DSG tune will also typically provide the option for a user-controlled launch control RPM. Some early DSG models had launch control defeated in Australia models, so this essentially taps into that factory Euro-spec option and adds some adjustability for better functionality. It is worth noting that for most front-wheel-drive cars, the launch control option just results in a futile attempt to control wheel spin without sticky tires. On the all-wheel-drive models such as the Golf R, S3, TT RS, and RS3, launch control can turn them into absolute beasts off of the line.
