Hi All, I am new to this site so hello to you all. I have an annoying problem with my c220 CDi Estate the car is manual and a 2012 model with the amg alloy pack etc When the engine is warm (running temp 90 degrees or there abouts) I get a judder when pulling away in first gear from a standstill. fells like anywhere from the gearbox to the rear axle drive wheels. When its cold or hasn't been driven very long at temperature its fine, but as soon as you've done a few miles at temperature the judder appears but only from a standing position, if the car is at temp and parked up for a few mins or so with the engine off when you restart the engine and pull away it will judder, I can only imagine the problem is heat related rather then mileage. The juddering is inconstant sometimes worse than others. I have also noticed that when standing still (with eco off) if the clutch pedal is depressed fully the engine revs increase to around 1000 rpm when clutch is released they drop back to normal running speed. The car was checked by an independant MB mechanic who told me there was nothing wrong with the car really but did advise that maybe the throttle pedal needed replacing as this was a common fault, it was replaced but made no difference. Other than this problem the car is fine returning in excess of 60 mpg on long runs, any help would be much appreciated.
