2012 C63 AMG Coupe
Hi all,
Have been looking for a fair amount of time now and have found no definitive answer.
I picked up my C63 AMG PPP 2 months ago from a reputable dealer. It is still under warranty. 50k miles, mid 2011.
Im absolutely loving the car but have noticed that under partial throttle i get some vibration for a few seconds (the same feeling you get when you drive on the hard shoulder of the motorway) and the revs are inconsistent. Initially i thought it was the tyres but then i would notice it at other speeds.
It never has this issue when in neutral or being driven hard, but it is especially noticeable under partial throttle when going up a hill for example.
This is in comfort mode. It kinda feels like the gearbox is struggling at low revs and cant change. The power kinda stops while the vibration is happening and then it gets a gear and its all back to normal. It has happened a few times too when braking but nowhere near as often.
It doesnt really effect me but i seem to notice it a lot and im wondering what the issue is.
In summary:
Vibration and rev inconsistency at low RPM moderate throttle - hills especially
No issue at full throttle or neutral
Any ideas? Want to get this sorted under warranty.
Regards

The thing that causes me to wonder is why it never happens when the cars cold or doing short journeys. I drive to the station every day which is about 2 miles and I NEVER get this vibration, whether going up a hill or whatever. Only when I drive to work and get the car up to temp and speed does this occur, and only under partial load when accelerating, not standing still or full throttle. I guess we will get it sorted soon hopefully.

but this wouldn't make sense to be the problem if the problem is only in partial throttle from a stop then slowly accelerating. If it was wheel suds you'd feel the vibration the whole time you're driving partial throttle and full throttle

So I finally brought my car in to a local Mercedes shop, and the owner thought this issue was transmission related. So, he brought my car to a transmission shop right next door. Long story short my torque converter needed to be replaced. I thought my 2012 didn’t have a torque converter, but the car is back to normal.

LOL it doesn’t have a torque converter. Maybe they meant “wet clutch”. Whatever it is, they didn’t replace what you think they did.

When I was told it was my torque converter I kept questioning it. But I figured as long as the car is fixed, I don’t care what they called it
