Volkswagen Golf / Audi A3 DSG 7 Gearbox Problem.

Seven Speed Direct Shift Gearbox Control Unit (DQ200)

This DSG 7 control unit is a very common failure for vehicles built between 2003 – 2016 fitted with the DQ200 Direct Shift Gearbox (DSG). The most common reported symptom is a complete loss of drive due to not being able to select any gears, this will cause the EPC light to remain illuminated and the gear symbols will continually flash on the instrument panel. Often the main 30-amp fuse will be blown,  if you try to replace the fuse it will blow again while the DSG control unit remains connected.

If you attempt to read the fault codes stored in the gearbox system, then you may also notice the gearbox system fails to communicate with your diagnostic scanner, preventing you from reading any fault codes. However, If you are able to communicate with the DSG gearbox system, then you may have the following fault codes stored:

  • 16946/P0562/001378 - System Voltage Low
  • 005636/P1604 - Internal Control Module
  • P189C/006300 - Function restriction due to insufficient pressure build-up.

 If you are experiencing any of the above issues then this is usually a clear indication that your DSG 7 control unit has failed.

We are able to remanufacture (rebuild) your own DSG unit and supply an unlimited mileage lifetime warranty as standard. When we rebuild your own unit we use higher rated than standard components and ‘engineer out’ the original design flaw that caused your unit to fail in the first place, giving you the peace of mind that your unit will not fail again. If we rebuild your own unit then it will cost a small fraction of the cost of a new unit, and you will not need to program the unit back onto your car – simply refit, replace the oil and away you go.

A brand new unit from the main dealer is very expensive and will require programming onto the vehicle which adds further labour costs. Most worryingly is that the brand new unit that we have seen still have the original design flaw, so if you purchase a replacement unit from the dealer then you can expect it to fail again at some point down the line.

Outperforming the original:

This is a complete re-engineered solution for the DSG-7 family of mechatronics units, all failing components are replaced with our own re-engineered versions, designed from scratch to outperform the original OEM parts. Employing our in-house designed reinforced stainless-steel pressure build-up controls, polymer clutch actuation protection and control unit revision, complete HIL simulation redesign to ensure all shift actuators are meeting and exceeding original OEM specifications in real-world conditions.

Testing and rebuilding:

We fully test every Mechatronics unit before (first line test) and after (end of line test) the rebuild, using our HIL (Hardware In-the-Loop) DSG-7 Gearbox rig, this allows us to test your Mechatronics unit under real-world load conditions. This ensures that each rebuilt unit meets and exceeds OEM specifications. All common failing components are replaced with versions that are higher rated than standard, so you can be assured that once your unit has been rebuilt it will perform as good as, if not better than a brand-new unit from the manufacturer.

Turn around times (excluding weekends and public holidays):

The turn around time for rebuilding your own unit is currently 2-3 working days.

If you choose to buy a direct replacement unit from our stock then the delivery time is around 1 - 2 working days (when stock items are available).


If you would like to have your own unit fully rebuilt, then you have two options regarding payment:


Pay in advance:

This option will allow you to pay for the rebuild in advance of the unit arriving with us, this is the faster option as we will not need to contact you once your unit has been tested, we will just go ahead with the rebuild if it is faulty and then send it straight back to you. To pay in advance for this service please select your vehicle from the list above and click on the 'Get Yours Rebuilt' option.


Pay after testing:

With this option we will contact you with the results of the testing and if it is faulty you can then decide if you want us to go ahead with the rebuild or not, it is at this point you would need to pay. This option is a little slower but gives you greater control over whether you want the unit rebuilding or not once it has been tested. If you prefer this option, then please fill in this test form and we will immediately email you with full shipping instructions.
