Hi all - new to this forum. Recently bought a pre-facelift S63 coupe and started to notice a high-pitch whining noise coming from the rear of the car.
From what i noticed:
Be great to hear your opinions too!

From what i noticed:
- The whining noise is high pitched, almsot feels as if there is a moped trailing behind me
- The noise only comes on after 10-15min of driving
- I think the noise is more noticable at lower speed - most prominent when the car is slowing down (e.g. when you feather the throttle, you hear the noise more when you lift off the pedal)
- Maybe at higher speed the noise is just drowned out by the engine sound?
- It also becomes more pronoucned after flooring the pedal and traction control comes into effect
- Soemtimes when i drive over bumps i feel the car loses grip for a fraction of a second
- I can also hear the noise even when the car is stopped with engine on idle
- I can only hear the noise from the inside - cannot hear anythign from the outside (of course without having the car lifted on a ramp)
Be great to hear your opinions too!
