Hi all,
I'd just like to add my "thanks" for this tip as well. My 300tdi developed a squeak and after changing the belt (it was due a change anyway) which made no difference I then tried swapping the tensioner. This seemed to work for a few days but then it came back.
I then stumbled upon this post! Curiously it didn't work on the new tensioner but in a flash of inspiration I took the old one down from the shelf (tip - never throw anything away) and tried putting the penny behind this one and hey-presto, silence has returned.
My theory as to why it sounds like the water pump squeaking (I was all-but ready to buy a new water pump) is that this is closest to the tensioner so if the tensioner isn't quite 'true' it'll be the next pully along that is affected the most.
Many many thanks,
Steve
