Hi all - we've got a 2004 1.8t beetle and just recently the battery light has been occasionally coming on and going off - a bit randomly & not all the time - there doesnt seem to be a pattern to it.
I've had the bonnet up and theres a definite irregular squeaking noise coming from the serpentine belt area - I'm thinking that one of the ancillaries on the belt has a bearing thats on it's way out? I'm basing this on the possibility that the belt is slipping occasionally which in turn is causing the altenator to miss a beat. The battery is fine and whilst testing the charge when running, it's been relatively stable, around 14.3-14.7 volts, depending on load
If that seems sensible, is there any simple way to diagnose which ancillary it is? I've got my had down to the altenator and the a/c pump and neither seem to have any play in them.
Which is the most likely failure point. Mileage is 66k.
Cheers all
Mark
