Whistling sound when accelerating/decelerating?
Hi guys I have a 2009 x6. When I accelerate I can hear some sort of whistling sound and when I decelerate the whistling sound goes down. Is this the turbo spooling?
I was told it might be the turbo's warming up but even when I've been driving it for a while I still hear it. Thanks |

Post a video of you driving the car and maybe you will get feedback. a lot of the bmw cars use twin turbo technology and they all are super silent when it comes to engine sounds so you cant hear turbo spool from a regular x6, unless it has catless downpipes installed.
post video for accurate feedback |
