2010 Audi A4 - Random Stall
 

Some facts:
1. Got an oil change - Day 1
2. Hit a pole at low speed (front end), could have Jarred something, don't see anything visible - Day 3
3. Car stalled at low speed after stopping at a stop-light - Day 4
4. Pulled code P0341 - Camshaft position sensor. Replaced it - Day 5
5. Drove to work, drove home, stopped at intersection, car stalled in middle of intersection (didn't even get it past 10mph), turned car back on, drove home. - Day 6
6. Pulled codes, no codes shown - Day 6
7. Tested battery - 12.6v car off, turned on car - tricked from 12.6v to 13.8v - Day 6
** few months ago had all coils replaced **

From what I read, a low battery could make your car stall, but I don't know if 12.6 not running (car starts right up/lights are not dim/all instruments Ok), and 13.8v with the alternator charge, would cause this.

Any ideas what could be happening here, is it a battery or alternator issue?

Thanks

Normal full charged battery with key off and sitting for 15 minutes is 12.6 volts. If lower then it would need charge or replacement. Normal running voltage is usually between 13.7 to 14.2 volts. Anywhere in between is OK. At these voltages your battery and alternator are operating correctly. This would not make your car stall. You have an intermittent issue which would be hard to trace unless it gives a code. Possibly the dealer diagnostic system may find a fault but because it doesn't happen all of the time it would be difficult. At this point I would go to them. If it happens at stop or idle speed then I would look at the IAC or throttle body.

Thanks for your reply. I've read it could be many things, too many for me to look into. Going to take it to my guy, I'm sure he has a much more up to date scanner they use at the shop than I do.
