I've seen several videos of that being done on S63 engines, but I haven't done it myself.

I'll keep you posted on if/how that tool works. Also, did you need access from the bottom, or could you take care of it from above? Trying to figure out if I should have the car on a ramp before I start. Thanks.

For the ac belt, I needed access from the bottom. You could probably get away with doing the main belt from the top but it helped to have the bottom access for it as well.

I just got a 2013 with 65K and it whines just like videos in this thread. Did anybody get results from the tensioner or anything else?
Mine is a 6MT and only makes the noise when in gear and under acceleration and it sounds like it comes from the transmission or driveshaft area. This is not consistent with a tensioner in my opinion because the whine is not present in neutral at any RPM. |

I’m having same issues as you kevlarblue also a 6MT. Have you made any progress in identifying the whine? I gave DP and AFE intakes too, but I don’t think they’re related. |

Foolishly, I took it to the dealership for the flush and thought they might have an answer or be able to diagnose the noise. They were reluctant to even do the flush because it's a "lifetime fluid" and they don't recommend it (even though the technician does it for his personal M4). Their next course of action would have been to remove and inspect, but ultimately replace, the transmission at a mere cost of $19,600. The technician suspected the noise is coming from a bearing on the input shaft. I disagree with that because it sounds nothing like any bearing I have ever heard (whining like gears vs a growl or grind like a bearing) but I am not a trained mechanic. For now, I am going to just live with the noise and continue to drive and enjoy the car. Hopefully a resolution or some information will present itself. |
