Any help appreciated: I have this motorized sound (3 second brrrrr) that comes from the rear wheel area. It sounds like a small motor coming on for the suspension or something? I hear it when mainly when accelerating and RPM is at about 1500. Does it in neutral also if I push on accelerator. It sound just like a small electric motor performing some function in rear of car.

 

My old 2.8i Granada had an electric fuel pump that `buzzed`

 

what year XKR? probley a heat shield buzzing.

 

Jagtech, it's a 2007. The motorized sound ONLY happens when the accelerator is pressed at about 1000-1500 rpm. Comes from rear driver wheel well. I can make the sound in neutral when pressing accelerator also. It sounds like s small motor and always last 2 seconds and shuts off. Happens every acceleration.

 

best thing to do is have a dealer look at it. i cann't tell you want it can be when i don't hear it and making it happen. you know what i mean.
