S4 Idle pulley whine and replacement.

[Jamestnewson]

I’ve got a whine when the engines running which accelerates in pitch with acceleration and suspect the idle pulley bearing is going.

Has anyone replaced theirs and anyone know if you need to replace the belt tensioner at the same time.

Not sure Audi still sell the tensioner or not as I can’t find one.

have you tried looking on autodoc.com?

Yeah I tried them. They have an idle pulley but not the tensioner.

Might have to keep searching.

Do you have the part number because if you don't look it up on the online etka parts database locate and write the part number down, than search eBay with that part number, ( you can even use it directly on search engines like google etc) that way you should be able to find it.

Thanks for that resource, it’s one I’ve not come across before.
