knocking noise coming from engine (s3 8p)
Was wondering if someone could help me diagnose a rather concerning issue im having!
Basically when I went to work last night, car was fine, however when starting it up after finishing this morning, there is this rather loud rapid knocking noise, that speeds up and slows down with the revs.
I stuck my head under the bonnet, and its coming from the left side of the engine bay (looking at it from the front) somewhere off of the drivebelt. Possibly alternator, but sounds like it could be further down into the engine bay.
Anyone experience similar issues or any ideas what it could be?
