Be aware if your serpentine belt all of a sudden falls off!!, after a couple of hours of taking things apart and trying to fit a new belt I couldn't work it out why I had so much belt slack ???.....then I realised I was missing a pulley....sure enough #4 wasn't anywhere to be seen...snapped off...entire bolt sheared back to the alternator housing.....maybe a weak point waiting to happen worth getting a new bolt and doing just in case.....vehicle has just turned 100.000miles

Sorry after checking your post/ real oem diagram looks like it's the other belt, as it says the tensioner for the power steering pump.

Re: Deflection Pulley
Well yes Horizon, that must be the one as you do lose power steering all you dont lose is air-con, my garage is awaiting a new bolt from BMW which holds the pulley on and is special steel 150mm in length, none in stock and coming from Germany which is a good sign as they would have a few in stock if it was common....although mine is not on the recall list.....
