I have a MK7 Golf with low mileage, no prior electrical or electronic component issues.
While attempting to install a battery maintainer, the negative battery cable popped off the post and caused a spark when it touched back down. I decided to not risk other problems while I was fighting with the leads on the battery maintainer so I disconnected both battery cables and covered the battery with a heavy cloth until the leads and cables were secured.
Once I reconnected the battery and started the ignition I had a bunch of Malfunction Indication Lights appear in the instrument cluster. I scanned all the control modules with my VCDS and found that now I have errors on these modules:
01 (Engine) --> multiple databus errors concerning the accelerator and brake fault statuses
03 (ABS Brakes) --> steering angle sensor
10 (park/steer assist) --> 2 databuses received an error message
13 (Auto Dist. Reg) --> 4 databus error or implausible messages
3C (lane change) --> 1 databus error message
44 (Steering assist) --> steering angle sensor not initialized
A5 (Frt. Sens. Drv. Assist). --> databus received error message
Does anyone know from personal experience with a Mk7 VW, not mere speculation if these messages are likely to go away on their own if I take a 20 minute drive to allow the car to re-learn or re-calibrate something? Or do these control modules need to be manually re-initialized due to the temporary loss of power? Or does this combination of DTCs indicate that the spark on the battery terminal actually damaged some of the control modules?
