A6 c8 30L Quattro diesel

[Charliie]

I have a6 30l c8 that started dying on me the other day and took it to the garage and they said the battery is not charging on it said it’s the alternator. The car has only got 68000  on it. I was just wondering if anybody else has had this issue. Pls help? Could it be something else? My first error message before it died was⬇️ just sceptical changing it because there like £2000 just for part

68000 miles is perhaps a little earlier than expected for an alternator to expire, but not unreasonably so. Get the garage to test the battery when you change the alternator as it may have been damaged by continual discharge.

However look at another recent topic on this forum regarding "brake servo restricted" for further enlightenment.

When the car is running, the batteries only chucking out 12.2 V that’s why I think is the alternator

I am not disagreeing.
