Hi guys.. New here
I have a 2004 A4 B6 1.9TDI
I had an issue of my brake lights (taillights) staying on all the time
Also ESP and handbrake light is flashing on the dash.
When brake lights On car crank but won't start but after switching off key and switch On when the brake light eliminated car starts fine.
Got it scanned it showed the brake light switch so i replaced it but still the problem occurs.
Howver on the dianogtics it also showed 01314 - Engine Control Module (ECM) no communication
01316 - Brake Control Module - no communication
