Strange electrical issues
Hi all, I had a strange electrical surge/short the other day which created a tonne of error codes but they cleared straight away and it hasn't come back.
So, I was driving to Manchester with a friend to pickup a car for him, it's about a 2 hour drive for me it's probably the longest continuous drive I've done in the S8 since I bought it. Car drove flawless the entire way. We got about 30 seconds from our destination and suddenly the car jerked/jumped and all the dash electrics went off. Everything suddenly lit back up and I had a red "Brakes!" warning message that went away as soon as it appeared. I turned the engine off, waited a few seconds and started it again, no warning lights or nothing so we drove down the road to our destination. Whilst my friend was viewing this other car I used my carista (I have VCDS I just need to buy a new laptop) to scan the codes and it displayed the attached. I cleared the codes and almost everything has disappeared and not come back, the only stuff that has returned are the items I am aware off such as the wiper motor control and tweeter motors. Transmission: 49478 P0562 - Ultrasonic sensor right for theft alarm system (G171) ABS: 02083 - Message for Delay Request 01299 - Diagnostic Interface for Data Bus (J533) 01299 - Diagnostic Interface for Data Bus (J533) 01315 - Transmission Control Module (TCM) 01314 - Engine Control Module (ECM) Parking brake: 00456 - Control Module for Access and Start Control (J518) 00576 - Terminal 15 01315 - Transmission Control Module (TCM) 02443 - Control head 02596 - Rear brake pads worn Instrument cluster: 00668 - Supply Voltage Terminal 30 Radio: 00532 - Supply Voltage B+ 00447 - Function Limitation due to Voltage to High 00856 - Radio Antenna Sound system: 03017 - Motor for Tweeter front-left (V344) 03016 - Motor for Tweeter front-right (V345) 03000 - Amplifier for Digital Sound package (R184) TV tuner: 00447 - Function Limitation due to Voltage to High Heater & air conditioning: 00065 - Left Rear Footwell Heater (Z42) 00066 - Right Rear Footwell Heater (Z43) 00604 - Potentiometer (G113) in Positioning Motor for Air Flow Flap (V71) Auto-leveling suspension: 01400 - Suspension Level Control Central electronics: 00908 - Control Module for Wiper Motor 00908 - Control Module for Wiper Motor Body/convenience system: 01134 - Alarm Horn (H12) 01134 - Alarm Horn (H12) Driver's door: 00913 - Window Regulator Switch: Front Right (E81) Ignition authorization: 00191 - Passenger's Door Handle Touch Sensor (G416) 00955 - Key 1 Battery regulator: 02272 - Static (Quiescent) current stage 1 02273 - Static (Quiescent) current stage 2 02276 - Static (Quiescent) current stage 5 02274 - Static (Quiescent) current stage 3 02277 - Static (Quiescent) current stage 6 Roof electronics: 00211 - Control for interior lights in the back 02138 - Activation for Right Front Interior Lights 00308 - Supply voltage engines sun roof/Rolo sun roof Adaptive cruise control: 01316 - ABS Control Module 01315 - Transmission Control Module (TCM) The car drove back fine, although I did drive it without radio and the head unit was turned off. And it has not done it since. Any ideas where to start with this? |
