Vibration at partial throttle
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.

Hi all thanks for responding.
I convinced myself that it was the spark plugs or an engine missfire that was causing the issue, but I just had a service today (new spark plugs, oil, filters, brake fluid) at a MB dealer and the issues still there. I never get CEL and no codes show up on the code reader.
In the UK we had the facelifted 204s since 2011. Mine is mid 2011 and is facelifted, new head bolts etc and engine number over 67000. Im almost certain it is identical to the 2012 onwards which is when the US got the facelift. I've been looking around and these cars have a wet clutch and not a torque converter so that can't be the problem.
I've therefore narrowed it down to two issues, and after searching the flex discs sounds like that's where the problem lies. I get vibrations that feel like they're coming from under me rather than the engine and when in manual or under full load it shifts perfectly so it's not a wider transmission problem. I'll look into engine mount issues but I will get it taken to a shop within the next few weeks and get this diagnosed and fixed, and feed back. Thanks for your help.

its a design flaw, the steering wheel is on the wrong side.

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.

make SURE they drain torque converter fluid also. You should notice a difference within 20 miles as new fluid cycles through.

Had same issue with my CL63. Changed flex disc, Carrier mount, tranny mount and engine mount... Change your fluid and make sure they drain the torque converter fluid also. check the fluid with magnets and you'll see the fluid will be very dirty(hopefully no metal shards).

Yeah just checked service history and last time transmission fluid was changed was 6 years 35k miles ago... Taking it to main dealer next week, will take the technician out to recreate the problem and get him to check fluid first before anything else
