Air con belt/pump it was!

Could it be the air con compresser or belt tensioner as opposed to the serpentine belt? Assuming you have air con of course. That is manually tensioned so could be a bit loose.

I was just about to replace the power steering pump (s/h £33 - ebay with 60 day warranty) when i thought - hang on that air con belt looks a bit tight - and it was really tight - so i loosened, then removed the air con tensioner from the engine and the belt was still too tight to come off the pump. So i loosened off the air con pumps bolts to give some slack and removed the belt. Put the aux belt back on, started the engine and "Hey Presto" the Squeak was gone!
Hmmm - the garage had sourced that and put it on. When i took it in i had bought the serpentine and aircon pump belts from BMW. The garage had phoned me up and said it was the wrong belt (air con) and they had to get the right one. But the one they got was also too short - about 1cm longer than the Beemer one. The one that was replaced was definitely much longer - when the tensioner was loosened with the old one you could slip it off no problem! They must have forced it on and now i expect the bearings in the air con pump are shot!
Moral of the story - Do it yourself
