I am having trouble with a noisy poly v belt on my W124 (1994 E280). The belt is in good condition, just slightly noisy. My local Mercedes Specialist (Steve Pollard @ BSG in Blackburn), recommended putting a thin layer of bearing grease on the inner surface. I must admit I was slightly alarmed at this. Being a Chemist I was well aware of the degenerative effect of grease on rubber. However he assured me that this used to be standard practise at the dealerships and works a treat, with no ill effect to the belt. Does anyone have any comments on this solution? I do know that Mercedes now produce a poly V-belt lubricant, part no 000 989 19 60. Perhaps this would be the preferred option.

PS I am based in the UK
