That moment, car stalled and it won't let me restart the car. …”
NHTSA complaint #11196839, filed 2019-04, 240 miles“Driving on the highway during a road trip from florida to wisconsin, our engine stalled while coming to a stop. We managed to get it to an Audi dealer and it was determined both turbochargers were broken. Both shafts had snapped and the car was un-drivable leaving us stranded in georgia. This is a design issue for the 4.0t engines and vw/Audi has refused to implement a fix beside the oil screen band-aid. The oil screen, since it is not serviceable, will slowly accumulate debris and restrict oil flow to the turbos and cause them to be starved of oil. …”
