This Audi A6 came in with electronic parking brake issues.
After diagnosis, we traced the fault to a damaged wire hidden within the wiring loom under the carpet, running from the park brake switch in the centre console to the park brake control module in the boot. Water ingress had allowed the loom to sit in water, causing the wire to corrode and fail.
Fault located, wiring repaired, and the parking brake system back operating correctly. ✅
