Alternator failing? Or control modules?

Born-Boysenberry3536B to Mechanic Advice@gearhead.townEnglish · 1 year ago

I have a 2012 b8.5 3.0TDI Audi a4. Get the alternator not charging notice on dash Test and it’s 11V so yes not charging. Sometimes I’ll test it and it’ll be 13-14V and not showing fault. Seems like it’ll run well for 20 mins then restart and no good for the rest of the day. The battery seems good, no issues starting or using stop start before hand.

Keep discussion friendly, civil, courteous, and professional. We’re here to help so being rude won’t help. Don’t assume a shop is trying to “rip you off.” It’s okay to ask for a second opinion.
