Alternator failure related to mild hybrid system?

Hello Neil

Our alternator stopped completely so battery didbt work. 

Rescue service guy charged the battery but it only lasted about 10 minutes at the very most. 

We only turned engine only to help park in drive way, which again the car only drove for 5 mins, by that time the battery had drained. The alternator wasnt doing anything. 

Hope that helps.

Hi,

so same happened to me… A7 50tdi 2019, all codes matched the document from previous posts, Audi UK pays for everything. Dealership said that the issue is known for about half a year and I should get back my car on Monday. Buckinghamshire

Has anyone got experience of having this replaced with TD1 registered? Work was approved then declined by local dealer as TD1 flag detected. I had EGR mapped out earlier this year after spending fortune replacing the intake manifolds. 
Dealer are saying it’s no longer covered under the 7yr warranty. 
I’ve escalated to Audi, not holding breath, but wondered if anyone else has had experience in similar situation.

I doubt it Richard. Any significant modification usually invalidates the warranty, whether it is related to the problem or not. For your sake I'd be glad to be proved wrong.
