Alternator noise
« on: 03 January 2011, 21:39 »
Hi, got a whinning coming from the alternator area of the engine. The VW garage said it was the alternator, so i replaced it, which has improved the lights alot which is great but the noise is still there.

Any ideas as to what the noise could be, alternator belt or cam belt. Alternator belt is fairly new and the cam belt should of been replaced as it was serviced at VW until about 90,000 miles.

Regards

Greg.

Could be the cam belt tensioner or belt too tight.
