When the gearbox won't behave, we're who the workshops call.
Replacement mechatronics, bricked TCUs, wrong software after a gearbox swap, generation conversions — this is the work we do every day, for tuners and transmission workshops who need it solved remotely and correctly.
Manually diagnosed. Manually built. No generic files.
Welcome to DSGFiles.com
You've spent thousands on an engine remap. Your dyno numbers look promising. But something's holding back the result — sluggish shifts, torque cuts mid-pull, a gearbox still living in factory ECO mode. That's not an engine problem. That's a gearbox software problem.
Every automatic gearbox rolling off the production line — DSG, ZF, Aisin, BMW DKG, Mercedes 9G — ships with torque limiters, conservative shift maps, and protective software designed for the average driver on an average day. When you tune the engine beyond those assumptions, the gearbox fights back.
We fix that !
The Name You Won't See on the Dyno Sheet — But You'll Feel on the Road
We're not a tuning shop. We don't chase likes or post dyno pulls. We're the company that the best tuners in the World call before they sign off on a build. We don't like to brag or point fingers , but this is the truth !
DSGFiles.com specialises exclusively in automatic gearbox software — custom TCU remapping for VAG (VW, Audi, Seat, Skoda, Porsche), BMW, Mercedes, Lamborghini and more. We are the transmission layer of a complete tune.
When your customer's engine is making 500hp and the gearbox is still torque-limiting at 380 — that's where we come in. We offer professional remapping solutions for DQ200, DQ250, DQ381, DQ400, DQ500, DL501, VL381, DL382, AL1000, AL450, AL551, AL552, AL651, AL951, ZF 6HP, ZF 8HP, BMW 6HP / 8HP, Mercedes transmissions, and more.
Why Choose DSGFiles.com?
Manually Processed, Every Time
No automated portals, no copy-paste jobs. Every file is individually analysed against your software version, hardware and modifications.
Unmatched Coverage
~95% of VAG gearbox software versions in our library, constantly expanding. If we don't have it, we'll build it.
30–90 Minute Turnaround
Because your workshop can't wait days. Fast, but never automated.
One Provider, Full Picture
TCU remaps, flash files, SGO/FRF/BIN conversions, IMMO services and DAMOS files — everything in one place.
Years of Specialist Expertise
Deep experience with DSG gearboxes, TCUs, electronics, mechanics and hydraulics — not general ECU work.
Custom Solutions
From a special file request to advanced remapping and IMMO work, we handle complex requirements too.
Comprehensive DSG Remapping Features
Increased Torque Limits
Raise or remove factory torque limiters to support higher engine output after ECU tuning or hardware upgrades.
Improved Shift Speeds & Points
Faster, smoother gear changes and optimized shift strategy in Drive, Sport and Manual modes.
Increased Clutch Clamping Pressure
Stronger clutch engagement to handle higher torque and reduce clutch slip under load.
Enhanced Launch Control
Improved launch settings for stronger acceleration, smoother launches and better traction.
Compatibility with Engine Modifications
Gearbox behaviour adjusted to match upgraded engine software or hardware.
Vehicle-Specific Adjustments
Custom modifications based on vehicle model, gearbox type, engine setup and driving style.
Plus shift-pattern customization, fuel-efficiency tuning, kickdown removal, speed-limiter removal, gear-display activation and more — see the full feature list on each product page.
Built for Professionals. Available to Enthusiasts.
Tuning workshops & remappers
Stop delivering half-finished results. A 400hp remap through a stock TCU is a 400hp remap with a 300hp bottleneck. We work with workshops across Europe to ensure the gearbox matches the engine, every time.
Performance car owners
If you've remapped your engine and still feel like something's missing, you've found the answer.
Dyno operators
Perfect runs start with a gearbox that delivers torque consistently, shifts predictably, and doesn't cut power mid-pull.

What is the delivery time for DSG Tuning files?
If you request custom DSG Tuning the delivery time for the files is between 30 and 90 minutes. Remember we do not run a tuning portal and all the files are analyzed individually and manually modified as there are always minor diferences between software versions.
What is Immo OFF?
Immobilizer off - refers to disabling the vehicle's / gearbox immobilizer system, which is a security feature designed to prevent unauthorized starting of the engine. When the immobilizer is "off," the vehicle can start and run without verifying the presence of the correct key or transponder, bypassing the security checks. This is often done for troubleshooting, repairs, or in cases of custom modifications but may also pose security risks if not managed properly.
I have purchased a file, how can I download it?
When placing an order for a file purchase , the DOWNLOAD link for the file it is ALWAYS on the order confirmation mail. Please look for the download link. You can also log into your account and download the file from your account.

Need a Different Format or Size? In case your chosen file is a STOCK / ORI BIN, yet you require an SGO / FRF version, please feel free to inquire. We might just have what you're looking for, which can be added to your order at no extra cost. If we do NOT have the file in the desired format already made, conversion might involve extra charges.
For any IMMO service we will allways need both FLASH/MICRO and EEPROM data. The immobilizer system it is always calculated in the EEPROM but some information is also contained in the FLASH.

VAG .sgo and .frf files are software flash files used by Volkswagen AG brands (like Audi, SEAT, and Skoda) to update or reprogram vehicle control modules. The .sgo extension is used for older KWP2000 protocols, while .frf is used for newer UDS protocols. These files contain the necessary software for modules like the engine control unit (ECU) or transmission control unit (TCU) to function correctly, allowing for updates, fixes, or even downgrades.
What they are
.sgo files: These are "SGML Object Files" used for older vehicles and protocols.
.frf files: These are "PerFORM Compressed Database" files used for modern vehicles and the UDS protocol.
Flash files: Both types are flash files, which are essentially the software that runs on a vehicle's control modules, such as the ECU, TCU, ABS, or infotainment system.
What they are used for
- Software updates: When a manufacturer releases an update to fix bugs or improve performance, these files are used to apply the new software.
-Reprogramming: They can be used to upgrade or downgrade the software on a module, allowing technicians to install a specific version.
-Module recovery: In case of a malfunction, these files can be used to restore a module's correct software.
-Diagnosis and repair: They are essential tools for anyone with specialized diagnostic equipment for VAG vehicles to perform module maintenance
SGO / FRF Files are to be flashed with ODIS Engineering or Vag Can Pro , Mechaprog or any other tool that can flash this type of containers. Flex can flash SGO via the Update module function.
SGO / FRF Files can not be flashed with tuning tools like Kess, PCM Fash , Dfox, Bflash , CMD etc.
