Since 2005 TVS Engineering / DSG Dokter is the pioneer in DSG and Engine diagnostics, repairs as well as software and hardware developments. What makes TVS unique is that they cover all required aspects in-house: diagnostics, repairs, overhaul, parts supply, performance hardware and software solutions.

TVS Engineering / DSG Dokter headquarters is located in Varsseveld, the Netherlands. Here a team of over 30 employees perform specialised work in the following departments:

• A technical centre and workshop for engine and DSG transmission diagnostics and repairs
• An overhaul department for DSG mechatronic, gearbox and engine overhaul
• A software department included chassis dyno for software development and dealer file supply and support
• A logistics department for premium DSG parts supply

TVS Engineering / DSG Dokter specialises in all VAG brands (Audi, Seat, Skoda, Volkswagen, Porsche) and cars and in particular the DSG / S-tronic / PDK equipped ones.

TVS believes that the only way to deliver the best and highest quality products/solutions is to specialise in a specific group of vehicles. When you want to focus on all brands and types of vehicles, there will always be an expense of expertise and quality.

PERON Automotive oversees and represents TVS in the UK and Ireland as their distributor.

TVS products are sold and installed through a global network of companies called authorised dealers. These companies are selected by TVS Engineering / DSG Dokter and PERON Automotive for their potential and ability to properly represent, sell, install, service and support TVS products and services.

All authorised dealers have a workshop, TVS dealer flashtool equipment and can utilise the online dealer support. Some of these dealers may have a webshop on which they are authorised to sell TVS products as well.

Engine tuning should always go along with reprogramming the DSG software. Many tuning companies claim that DSG software upgrades are not needed for tuned vehicles. Often tricks are being used to disable DSG torque intervention commands or engine torque calculations are manipulated to stay within factory margins and avoid DSG torque limitations. All these types of incorrect ECU adjustments along with stock DSG software will result in excessive clutch wear, shifting problems, potential performance loss and gearbox breakdown.

Many stock VAG equipped DSG vehicles suffer from factory drivability issues. Extremely poor shifting strategies which don’t match stock engine characteristics properly, resulting in too early shifting at low load and too late shifting at high load. Basically all VAG DSG transmissions will strongly benefit from a TVS Drivability upgrade.

The functioning of the DSG transmission strongly depends on real-time engine running parameters received through the CAN bus. The transmission control unit (TCU) of a tuned vehicle with stock DSG software receives usually incorrect data from the engine, resulting in incorrect (or limited) initial TCU calculations.

Initially no issues might be noticed, but after a period of learning incorrect adaption values and increased wear (due to increased slip) the clutch will breakdown. Besides all the risks of excessive wear and breakdown, the DSG needs to be reprogrammed to perfectly match the new engine characteristics. In other words matching shifting strategies, modified shifting speeds and increased torque capacity and oil pressures will be needed to fully utilise the vehicles performance potential!

TVS DSG software upgrades are certainly not only needed for tuned vehicles. Basically all VAG DSG transmissions will strongly benefit from a TVS Drivability upgrade which truly transforms the performance of a vehicle and even massively increases the drivetrain lifespan due reduced flywheel, clutch and gearbox wear!

In almost all cases official VAG software updates don’t solve your DSG transmission problems. The explanation is simple: TVS discovered that most DSG issues are deeply hidden in the basics of the factory software. We solved these issues by completely recalibrating the factory software. An official VAG software update, on the other hand, is only a minor modification whereby the base software is still incorrect and doesn't solve your DSG issues.

When an official VAG dealer performs a gearbox software update, custom TVS software will be overwritten and lost. For this reason we offer our customers a free lifetime service by reflashing the TCU with their purchased TVS software. In case the customer wants custom TVS software based on an updated software version a small fee will be charged.

TVS Engineering offers custom software solutions for all VAG DSG transmissions and models:

• DQ200
• DQ250
• DQ380/381
• DQ400
• DQ500
• DL382
• DL501

TVS Engineering offers the best and widest ranging DSG software upgrades available on the market. Not only the strongest and most powerful ‘off-the-shelf’ and fully customisable software solutions, but also the best possible durability and drivability upgrades.

TVS DSG software solutions are divided into five categories: from drivability upgrades for stock vehicles up to Stage 4 tunes for true performance vehicles and motorsport applications. Read more about TVS DSG software Stages explanations here.

Stock (non-tuned) vehicles will strongly benefit from a TVS Drivability and life extender upgrade which truly transforms the performance of a vehicle and even massively increases the drivetrain lifespan due reduced flywheel, clutch and gearbox wear!

For tuned vehicles TVS offers different software Stages. It is vitally important that at the very least the maximum supported gearbox torque matches your engine application.

For performance applications we advise Stage 2+, Stage 3 or Stage 4 depending on various mechanical and usage factors.

Contact PERON Automotive to discuss your goals in relation to your vehicle.

For a perfectly running DSG transmission the ECU software is as important as the DSG software, since the functioning of the DSG strongly depends on real-time engine running parameters.

The combination of our specialism in both Engine and Gearbox tuning is what makes TVS software packages unique. Developing both Engine and Gearbox software in-house gives TVS the ability to perfectly match your Engine to the Gearbox and vice versa! This results in an incredible driving experience which simply couldn’t be compared to individual purchased ECU and TCU tunes.

TVS Engineering is able to match their gearbox software to ECU tunes from other brands. However, one important condition is that there are no incorrect ECU adjustments performed in the third parties ECU software like manipulated engine torque calculations or disabled DSG torque intervention commands.

At PERON Automotive we partner with a handful of selected tuners that provide ECU tunes that work in perfect synergy with TVS and their DSG mastery.

TVS DSG racing clutches are designed to increase clutch torque capacity to the maximum without sacrificing reliability or drivability. To achieve this we carefully balanced the friction surface area, friction materials, plate designs and clutch pack shimming. A perfect balance between different aspects is the key for an excellent performing DSG racing clutch!

TVS DSG racing clutch upgrades are characterised by:

• Factory drivability
• Increased torque capacity
• Increased thermal capacity
• 100% new clutch assembly
• Plug & Play solution
• Proven design for years

TVS Stage 3 software is the strongest DSG software available on the market wherein maximum physically possible clutch pressures and extremely high stock clutch torque capacities are achieved. If your engine application produces more torque than the maximum supported engine torque of our Stage III software, you simply do need an upgraded race clutch!

Contact PERON Automotive to discuss the maximum supported engine torque on stock clutch for your DSG model together with TVS Stage 3 software.  For motorsport / racetrack applications TVS always advise to use their upgraded race clutches!

TVS Engineering offers upgraded race clutches for almost all “wet clutch” DSG transmissions: DQ250, DQ380, DQ381, DQ500 and DL501. TVS Engineering has consciously chosen not to develop an upgrade race clutch for the “dry clutch” DQ200, because this transmission is simply too weak. We recommend our DQ250 conversion for DQ200 applications running above 350 Nm engine torque.

TVS DQ250 DSG racing clutches are running strong and reliable for years without any major modifications after the first release back in 2009. Based on this knowledge and experience TVS further expanded their DSG race clutch program with the DQ380/DQ381, DQ500 and DL501.

It is absolutely needed to upgrade the TCU software after installing an upgraded DSG race clutch.

TVS Stage 4 DSG software is custom made software for TVS or aftermarket DSG upgrade race clutches.

For applications where even TVS Engineering's unique software solutions and upgraded racing clutches are not quite up to the task of handling high performance applications, TVS Engineering offers DSG gearbox conversions. The basic TVS DSG conversion kits contains the following parts:

• New upgraded DSG gearbox included mechatronic and clutch
• All additional parts needed for the conversion like flywheels, driveshaft(s), wiring adapters, engine- and gearbox mounts, etc. (varies by model)
• TVS conversion software included immobilizer solutions (if necessary)

On high power applications almost all VAG DSG gearboxes will have mechanical limitations resulting in a very limited lifespan and/or gearbox failure. Even with TVS DSG racing clutches and unique DSG software solutions gearboxes will not withstand all power potential from true high performance engines. For these applications we recommend TVS DQ500 conversion kits.

In addition TVS Engineering offers DQ250 conversions for DQ200 equipped vehicles. These “dry clutch” DQ200 gearboxes are known to have a lot of issues like excessive clutch wear and gearbox breakdown already at low performance. For example with chiptuning almost all 1.6 TDI, 1.4 T(F)SI and 1.8T(F)SI engines the DQ200 transmission is the limiting factor. For this reason we often limit the engine torque at about 350 Nm for the reliability and lifespan of the DQ200. When you would like to achieve the full potential from these engines a TVS DQ250 conversion is necessary.

Finally, it is of course possible to convert your manual vehicle to DSG.

TVS Engineering offers DSG conversion for all vehicles with transversely mounted VAG DSG transmissions.

For DQ250, DQ380 and DQ381 applications TVS offers DQ500 conversion kits.

For DQ200 applications TVS offer s DQ250 conversion kits.

Chiptuning is modifying the software of the Engine Control Unit (ECU) to achieve increased performance, improved drivability and/or a lower fuel consumption. We at TVS always aim to achieve the best of all aspects!

After TVS technicians (or our authorised dealers) performed extended powertrain diagnostics we connect to the vehicle’s ECU to collect identification information and take a read of the factory software. This information is uploaded to the TVS Engineering HQ server from where our high educated automotive engineers could start optimising the factory software. Thereafter the custom made TVS software is returned and installed on the vehicle. Finally, the vehicle is extensively checked and data logged to guarantee a correct and safe software recalibration.

This depends on the conditions of the vehicle, engine type, hardware modifications and TVS software Stage.

For Stage 3 and 4 applications several different hardware choices (e.g. upgraded turbo) are required. Performance numbers only give here an estimation.

Contact PERON Automotive to discuss further.

Custom TVS software enhances and optimises the performance of your engine and transmission always within safe limits whereby it does not shorten the lifetime of your engine or powertrain. Vehicle manufacturers always apply a large safety margin on engines, because vehicles have to perform well under all circumstances worldwide and have to deal with diversity in fuel and oil quality, climates and conditions. TVS benefits from this high tolerance of factory margin.

This together with custom made software from TVS Engineering's highly educated automotive engineers, who fully understand all ECU functioning strategies and have in-depth knowledge about internal combustion engines, results in zero impact on the lifetime of your engine or powertrain.

For those who would like to achieve performance numbers far above factory ones with TVS Stage 3 or 4 software, there are for sure a number of possible risks associated with engine and powertrain life span.

If your vehicle is in for regular maintenance at a VAG dealer, TVS software will not be overwritten. This only happens when the dealer performs a so called software update.

TVS offers lifetime warranty on their software as long as you own the car. With this TVS will restore the software for you if it is overwritten. TVS usually does this based on the new software update and the old software modifications.

TVS Engineering creates a software backup of each vehicle and stores a copy in their database. This makes it possible to restore the software to its original state at any time when desired. In addition, TVS offers lifetime warranty on their software as long as you own the car.

TVS Engineering offers the best and widest ranging ECU software solutions available on the market. These are available for different performance levels, supporting various fuel grades and are suitable for vehicles with or without any hardware modifications.

TVS custom ECU software is divided into five different categories known as Stages: from mild performance increases (Stage 1/Stage 2) up to tunes for high performance and true motorsport applications (Stage 4).

Read more about TVS ECU software Stages explanations here.

Any vehicle will strongly benefit from TVS Engineering’s custom ECU software which truly improves the performance, drivability and/or fuel consumption of your engine!

For stock vehicles without any engine (setup) modifications, we recommend TVS Stage 2 software to totally transform your vehicles performance. Since at TVS Stage 1 is only a low budget solution for a mild increase in performance. With TVS Stage 2 the factory software will be fully recalibrated to achieve maximum performance within all safety limits.

For vehicles with a modified engine setup (e.g. upgrade air intake or downpipe) and stock turbo TVS recommends custom Stage 2+ software.

For vehicles with an upgrade turbo-/ or supercharger TVS custom Stage 3 or 4 software is recommended.

Contact PERON Automotive to discuss further or read more about TVS software Stages explanations here.

TVS Engineering is known for achieving the best performance from VAG engines without sacrificing drivability, reliability and durability! To realize this every vehicle at TVS is individually (re)calibrated and the ECU software is custom written based on vehicle condition, customer wishes and requirements. 

For a perfectly running DSG equipped vehicle the ECU software is as important as the DSG software, since the functioning of the DSG strongly depends on real-time engine running parameters. Too often we notice incorrect ECU adjustments (e.g. manipulated engine torque calculations or disabled DSG torque intervention commands) performed by ‘tuners’ resulting in potential performance loss, drivability- / shifting issues and transmission wear.

Developing both engine and gearbox software in-house gives TVS the ability to perfectly match your engine to the gearbox and vice versa! This results in an incredible driving experience which simply couldn’t be compared to individual purchased ECU and TCU tunes.

In addition custom TVS ECU software has various unique optional features like enhanced temperature protection, optional motorsport (hard cut) and more. See the optional ECU features for the full overview.
