Tackling some noise in and around the fanbelt, I found worn bearings in the fanbelt pulley and the guide pulley, which I will be replacing. I also found that my fanbelt tensioner was at the limit of adjustment and also needs replacing.

Checking back thugh my records, I find that this item (124 200 08 70) was replaced in October 2003 by the dealer shortly after I bought the car. Since then the car has covered around 20,000 kms.

Surely this can't be right? I can't believe that a fanbelt tensioner would need replacing that often.

Anyone have any experience with this?
