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 |
DQ381 (0GC) Repair
The DQ381 (0GC) transmission control unit is a modern 7-speed dual-clutch gearbox (DSG) that is installed in many VW, Audi, Seat and Škoda models. As with many electronically controlled gearboxes, defects can occur over time, making a DQ381 (0GC) repair necessary. Problems can manifest themselves in jerky gear changes, delayed reactions or sudden switching to emergency mode. Early diagnosis and repair can prevent expensive consequential damage and significantly extend the service life of the transmission.
Common errors with DQ381
Typical problems with the DQ381 (0GC) include the pressure sensors and the clutch control unit. Error codes frequently occur which indicate implausible sensor values or a faulty transmission control unit. The following error codes are read from the transmission control unit using the tester:
- P0805 – Clutch position sensor function faulty
- P1735 (10666) – Clutch 1 position sensor, electrical error
- P1736 (10668) – Clutch 2 position sensor, electrical error
These errors indicate a defect in the position sensors of the clutches, which can lead to shifting problems or an emergency stop. In this case, only the defective position sensor is replaced to rectify the problem. A targeted diagnosis and repair can help to restore the transmission to perfect condition and avoid expensive complete replacements.
Frequently Asked Questions
How do I know my unit has failed?
A DSG mechatronic malfunction will of course throw a plethora of gear-related faults your way. Initial clunking or jerking while shifting may soon develop into a total loss of certain gears – before preventing any drive at all. It’s common for vehicles to enter limp-mode too when they’re in need of a DSG mechatronic repair.
Warning lights generated by this fault may differ between vehicles – check out our specific transmission-related pages. Generally, you’ll be greeted by ‘engine’, ‘transmission’, ‘EPC’ or ‘PRNDS’ warning lights when starting up your vehicle until the mechatronic has been repaired.
We’ll thoroughly test your control module on purpose-built testing rigs to establish whether the DSG mechatronic is in need of a repair. If you go ahead with our rebuild option, we’ll even waive the small testing fee!
DSG mechatronic failure – repair or replace?
As you’ll know, a brand-new mechatronic unit doesn’t come cheap and there’s every chance it’s still laced with the initial manufacturing defect that caused your malfunction. A rebuild on the other hand, removes the fault for good, costs less than a replacement, and evades any reprogramming costs of a brand-new unit.
We use higher-than-OEM-standard components to aid long-term durability and extend your DSG’s lifetime. We’ll even cover your fully-repaired DSG mechatronic with an unlimited-mile lifetime warranty for further peace-of-mind. We do all of this in just 2-3 working days!
We offer our test-and-rebuild service for the following mechatronic units: DQ200
How do I get my unit rebuilt?
