Whining noise at 2000rpm
i get a whining noise either when accelerating or decelerating to 2000 rpm. It only does it when driving, not in Park or Neutral. Any ideas?

I can't really hear anything out of the ordinary in the video.
If you're sure it only happens when moving then you need to check everything in the driveline - propshaft, driveshafts and wheels.

I had this on mine abiut 1 month ago - it was diagnosed as a failing tandem pump (combined pump for ABC and power-steering) My car is a 08 CL500, and has 69k miles on it.
The replacement part was £900 and the labour was £1100 (it is about 9 hours labour).
I would get it looked at soon (if you haven't already).

I am also having this problem. Did you ever get it diagnosed? It is different from the noise caused by accumulators going bad. I have had those problems in the past and replaced all three. It seems to me like the ABC pump getting tired but I am hoping not...

@Basso1001 Thanks for the info. Were you having an identical noise to OP? The whine only around 2000rpm on deceleration?
I ask because I changed my dampener 6yrs and 80k miles ago. The sound back then was very different. I find it hard to believe that it would be that again. If it is, I would be the first on these forums to have replaced it twice in one ownership.. a true wear item!

If you have replaced the damper then it must be something else. I had also a wining sound because my mechanic had changed the steering fluid for standar steering fluid. Thought my pump went bad and orderded a n refurbished one.
A few days later he called me and told me about the fluid, changed it and the noise was gone. These are very sensitive cars with lots of problems....

I agree with you, it's unlikely but something to think about: Like many on here, I changed my dampner when the car was ~10yrs old and ~40k miles. Since I changed it its been ~6yrs and ~80k miles. Based on that logic, it may need another replacement.
This sound is more subtle though and I think when the dampner goes, it goes completely and is much louder.
Hopefully OP responds because we are having the exact same noise at the exact same rpm/engine conditions.

As I wait on OP to check his inbox, I thought I would add a note for anyone else having this exact noise. OP does not have ABC in his car given it is a 2012. I do have ABC and am having the same sound... Implication being it is not ABC related.
