Renault Scenic Dci belt problem - Spanner
I have previously posted an item about a problem with an '02 reg Scenic dci with air con. Recently it suffered a thrown auxilliary alt/pwr steering/air-con drive belt. Another belt was fitted and tested with belt alignment checked out okay. However last week it has done exactly the same. The tensioner is doing its job, but we did notice that when new belt was fitted and tensioned, the belt oscillated between the air-con compressor and pulley - even when the belt has the correct 'give' and is tight between the other pulleys. (Belt was supplied by Renault).

The belt oscillation was up and down but not laterally as I would expect from a misaligned belt. An aircon engineer who checked out the compressor pulley/endfloat etc seemed to think the car has an incorrect alternator even though owner has owned car from new and has never had previous alternator repairs.
Car is a few years old, has full history yet has done over 100,000 miles.
Has anyone in the forum experienced similar problems with the Scenic and/or other Renault models?

This is commonly seen on these and is usually down to a failed one-way overrun clutch in the alternator's drive pulley.
