DSG Mechatronics Repair Austria
We offer a fast DSG mechatronic repair in Austria. One of the currently most common problems with the DSG 7 or DQ200 is the pressure loss fault. This fault is caused by cracks in the aluminium die-cast housing or a defective sealing ring. As a result, the transmission control unit can no longer build up and maintain the required pressure. But there are also some faults to repair with the DSG 6. You can find more information about the function of the DSG in the Wikipedia article Dual clutch transmission. Also for our professional Control unit repair and for the first Speedometer repair from Austria we have written interesting articles.
Repair kit for DSG mechatronics repair
With the repair kit for the DSG7 or DQ200, the pressure loss fault can be rectified. For the DSG mechatronic repair to be successful, the original pressure accumulator must be removed and a stainless steel insert inserted. Now the new pressure accumulator can be screwed into the insert. By using the insert, it does not matter if the aluminium housing is cracked.
Error codes and problems of the DSG7 mechatronics
The loss of pressure in the DSG7 mechatronics naturally causes various symptoms in the vehicle. Among other things, the gearshift indicator ("PRNDS") may flash, the gearbox may no longer shift correctly, or the fuse for the gearbox control unit may blow. Various error codes are also stored. Repair is possible for the following error codes.
| Error code | VAG code | Error description according to tester |
|---|---|---|
| P0562 | 16946 | System voltage error, voltage too low |
| P0841 | 17255 | Hydraulic oil pressure sensor |
| P1604 | 18012 | Control unit error |
| P177F | – | Hydraulic pump system, overload protection |
| P17BF | – | Function restriction, pressure drop |
| P1895 | 18303 | Functional limitation, lack of pressure |
| P189C | 006300 | Functional restriction, low pressure build-up |
Other fault codes for DSG7 or DQ200
Contamination by metal particles can lead to other error entries. First check the position sensors and magnets for contamination. If you notice any unusual contamination, the DSG must be checked for mechanical damage and wear. If you do not find anything, clean the sensors and check whether the error code is still present. If this does not help, it can be assumed that the pressure accumulator is damaged. This applies to the following error codes.
| Error code | Error description according to tester |
|---|---|
| P173A | Position sensor 1 for gear selector, improbable signal |
| P173B | Position sensor 2 for gear selector, improbable signal |
| P173C | Position sensor 3 for gear selector, improbable signal |
| P173D | Position sensor 4 for gear selector, improbable signal |
Installation-related error codes
After the DSG mechatronic repair and installation, the following error codes sometimes appear. These occur when one or more shift bolts are not correctly fitted in the gearbox shift forks. When installing the mechatronics, make sure that all bolts are correctly fitted.
| Error code | Error description according to tester |
|---|---|
| P072A | Gearbox stuck in neutral |
| P072B | Gearbox stuck in reverse gear |
| P072C | Gearbox stuck in 1st gear |
| P072D | Gearbox stuck in 2nd gear |
| P072E | Gearbox stuck in 3rd gear |
| P072F | Gearbox stuck in 4th gear |
| P073A | Gearbox stuck in 5th gear |
| P073B | Gearbox stuck in 6th gear |
| P073C | Gearbox stuck in 7th gear |
DQ250 (DSG6) Repair
The DSG mechatronic repair not only concerns the DSG7, but also the DSG6 as its predecessor. This has a completely different structure. This is why the resulting faults and problems differ. The term DSG6 stands for a DSG with 6 gears and DQ250 is the exact model designation of the DSG that is being repaired.
Common DQ250 problems
Usually, various error codes of the solenoid valves or sensors occur. This manifests itself in the transmission no longer shifting or only shifting randomly. Since the DSG6 is a hybrid control unit, a bonding machine is required for professional repair. You will find a brief explanation of this under "Internal structure of injection control units" in the engine control unit repair section. The following error codes can be repaired.
| Error code | VAG code | Error description according to tester |
|---|---|---|
| P0715 | 17099 | Gearbox input speed sensor G182 Error |
| P0722 | 17106 | Gearbox output speed sensor G195 error |
| P0735 | 17119 | 5th gear, wrong transmission ratio |

Error code P0716 (17100) and/or P2711 (19143)
The error code description is "Input/transmission speed sensor (G182) unlikely signal" and "Unexpected shift sequence". If any of the fault codes are present, the gearbox must be checked for metal abrasion and mechanical wear or damage. The transmission oil filter must also be checked. If it is clogged, the oil circulates through a bypass and is no longer filtered. If necessary, clean the gearbox and test whether the error code is still present.
