Car is a 2004 S4.
Battery light came on on the way home today. Ran VCDS, no fault codes showing. The battery shows 12.1V with engine off and 11.9V with engine running.
I'm fairly sure this points to an alternator failure (which is covered under warranty) but wandered what else it could be or anything else I should look out for first. Corroded/lose cable or anything? If it's just a loose cable etc then that ISN'T covered by the warranty! lol.
TBH I've not had much of a look round the engine on these things, so no idea even where the alternator is at the minute without googling so hopefully someone can point me in the right direction of what to look for!!
Cheers in advance!
