AUDI A4, A5, A6, A7, Q5, Model years 2018-2021

On Audi vehicles manufactured within a specific period, it is possible that moisture may enter the belt-driven starter-alternator. In unfavourable circumstances, this may result in chemical reactions which could in turn lead to local overheating in the component. A subsequent vehicle fire can also not be ruled out in this case. This can also occur on a vehicle that has been parked for an extended period.
