Volkswagen Golf / Audi A3 DSG 7 Gearbox Problem.

Audi Volkswagen 7 speed transmission fault

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.

Test and rebuild:

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.

HIL testing DSG7


All coding is retained during test and rebuild – no need for programming once you receive your rebuilt DSG7 unit back.



Our strict quality control: encompassing testing, components and workmanship will ensure only the highest level of work is carried out to meet our lifetime warranty standards.

Hi Roger, I would recommend that you check for fault codes within the transmission system first, however this type of DSG-7 mechatronics unit was not fitted to your vehicle, so you would also need to contact us with your transmission ECU part number for us to know if your unit is one that we can test/rebuild.
