Repair of the DSG transmission on a 2022 Volkswagen Passat GTE, including replacement of all seals and solenoids. The customer came to the service with an issue of jerking when changing gears and delays in gear engagement.
Diagnostics revealed a hydraulic problem in the DQ400 transmission caused by worn solenoids and leaking seals. We performed the following procedures:
- Transmission fluid replacement and analysis - Transmission electronics diagnostics - Partial disassembly of the transmission - Replacement of all solenoids with new ones - Complete replacement of all seals - System adaptation and calibration
After the repair, the transmission works like new, with precise and smooth gear changes.
