If your GTE displays "Error: Hybrid System," the car may refuse to start or switch to petrol only. We diagnose HV battery contactors, isolation faults, and the 12V DC-DC converter mobile.
- Deep Fault Scan
- HV Battery Health
- Isolation Testing
- Contactor Reset
DSG / Clutch Faults
The GTE uses a triple-clutch DQ400e gearbox. Jerky transitions between EV and ICE mode often indicate a calibration issue or mechatronics failure. We offer on-site adaptation and resets.
- Clutch Adaptation
- DSG Oil Check
- Mechatronics Scan
- Gearbox Soft-Reset
HV Heater (PTC) Repair
Common in London winters: if the High Voltage PTC heater fails, the GTE will often refuse to stay in E-Mode. We diagnose heater communication faults and coolant pump issues.
- PTC Heater Test
- Coolant Valve Fix
- E-Mode Logic Reset
- Thermal Analysis
Charging Malfunction
Problems with the "handshake" or a stuck charging pin are common GTE issues. We replace faulty port lock actuators and test the on-board charger (OBC) communication lines.
- Port Lock Swap
- OBC Diagnostics
- Latch Timing Sync
- Signal Trace
