C10E2 on Volkswagen by model: symptoms, diagnosis and fix
The 7P-generation Touareg's electronic parking brake can fail electrically, with a flashing yellow light on the EPB switch and a 'Park Brake Fault' dash message. In some cases the brake will not disengage, leaving the vehicle immobile, or it locks on due to actuator air-gap tolerance issues. The fault is typically traced to one of the two rear caliper park-brake motor/actuators or the EPB control module. A common scan code is C10E2 (Electronic Parking Brake control module electrical failure).
Common Symptoms
- Flashing yellow EPB switch light
- 'Park Brake Fault' dash warning
- Parking brake will not release / vehicle won't move
- Parking brake sticks on
How to Fix
Scan with VCDS/Ross-Tech and test resistance across the left/right park-brake motor pins (~10 ohms expected). Replace the failed park-brake actuator (commonly the right-hand unit); the original EPB module can often be refitted. If the brake is stuck on, the vehicle may need recovery to a specialist.
