2012 Volkswagen Passat

Asked by GuruCJT37 Mar 14, 2019 at 03:48 PM about the 2012 Volkswagen Passat

Question type: Maintenance & Repair

I have been running around in circles trying to
figure out what is wrong with my car. I have gotten
a new battery then later found out that it’s actually
the alternator that’s dead, so I bought a new
alternator and guess what still nothing. I got the
ground wire for the battery replaced and I just got
the starter fixed today. This is really frustrating that
after a new battery, alternator, and starter it still will
not start. So if anyone can help I’d really
appreciate it.

Did the dealer do any of the work? If not you may need to have the entire computer system reset if you did not use the keep alive memory tool before disconnecting the battery. The computer controls the charging system and looks for a specific voltage variation from the battery before it engages the alternator.
