I have a 2007 Audi A4 2.0 T. I am experiencing at idle only a very high pitched whine that only seems to occur when the car gets hot. We are in Dallas texas and ever since the summer temps came on I have had this noise. I am thinking the belt tensioner but thought I would check. No change with a/c on or off. Car runs fine.....
ok, does the belt tensioner only support the a/c, alt etc
nevermind, understand remove belt....got it. This should not affect the timing correct?
got cha, thank you. I assume if noise quits bearing in one of the pulleys could be issue. I have no charging issue as I tested this and the a/c does not affect the noise either way.
