2003 VW Jetta 2.8 VR6 6-spd manual trans
At idle or low speed coasting the car will essentially lose all power for a second. The dash/headlights/instrument cluster will all turn off and back on. The clock and trip odometer reset. The various warning lights will come on as if the key was just put in the run position. Then I can turn the key off and the car will start right back up.
Doesn’t happen at higher rpms. Car be in neutral and idling or if I’m taking off slowly or coasting along slowly it will happen. Battery voltage with accessories on is 13.9v. Battery terminals are clean and tight. I am going to dig into all the grounds but since the alternator seems to be working fine and the car will stall sitting still I’m not sure which ground would be corroded or broken since it wouldn’t be breaking contact while sitting in idle.
Any help is appreciated especially from vw/Audi techs.
