Good Evening everyone.

I am just wondering if anyone can help me out please on this small problem.

On my X5 40d M Sport  (M Sport Suspension Deletion), whilst travelling over rough surfaces/bumps in the road its what i think is the suspension/damper gives a single high pitch squeek noise. It cannot be heard when the windows are up but on a warm day its incredibly annoying as you can hear it quite loud and its embarrassing for me as members of the public will be able to hear it as i drive past !

It seems to be coming from the passenger side of the car, I have been under the car and sprayed everything behind all 4 wheels with silicone lubricant spray and had no luck. Its been happening for the past 3 months and ive just about had enough now and i want it sorted  )

Has anybody had this problem before or has anyone got any tips or advice for me please?

Thanks all.

I have this on my 40d 12 plate. I found over large bumps the squeak became a harsh shriek. It promptly went back to the dealer who told me they couldn't replicate it. However the car came back with much less squeak out of both from suspension units and the tracking / alignment done.

Others have suggested control arms / bushings are the cause, I will see if it returns and will claim warranty (AUC).

Thanks for the response
I still have 2 months Approved used warranty left on mine. But i thought before the hassle of booking it in etc.. if there is a simple quick fix that anyone knows of or if it is just a wear and tear issue that i can get repaired at a local dealer.

Both my E70 X5 and my E71 X6M suffer from this ; I've just accepted its normal for these cars now .

Saying that ; I rarely drive with the widows open
