Skipping
Yesterday the weather got worse over here in UK, much colder and much wetter.
I started the car, reversed and boom, this almighty noise and judder like I had gone over a big pothole.
Family were alarmed but car seemed to carry on without any further issues.
I phoned the dealer and agreed to see them today. Got in the car this morning, weather even worse and had some massive ‘skids/slips’ when turning full lock on both turning corners and reversing.
I get to the dealer and he nods his head immediately, calls it ‘skipping’ and agrees it’s a known issue with C, E class and particularly the GLC’s.
Supposedly it’s a combination of the 4WD system, low profile/hard compound tyres and low temperatures.
I was stunned that this was being admitted as an issue that they couldn’t rectify! He assured me it wasn’t a safety issue but not good nevertheless.
The dealer is a good guy and is going to raise a investigation to see if they can get me a free set of winter tyres as supposedly that helps it but this is mental for a £100k car!!!
I’m mystified, his story does add up as I had the E63 out on test in the summer and didn’t have an issue then.
Really disappointing as I am truly loving the car but this is a joke!
I thought I had done my due diligence and am kicking myself more than anything I didn’t know about it beforehand!

what kind of sound/feeling is that you described as i did not understand exactly what happened?
i live in a general hot country, but can get rainy winters and temperatures normally go to 0 to -5ºC at its peak. never used winter tires but i'm curious to know about these issues

Was a bit worried because by German law we were supposed to have winter tires on the car, but it was delivered with Pirelli summer tires. My dear and the tech at delivery told us that as long as we didn't get stuck and cause a problem in traffic we were unlikely to be ticketed.
So, summer tires in cold wet conditions, much as you describe.
Having driven a variety of 4x4 vehicles off and on road with a mix of limited slip axles and locking differentials, the skipping felt kind of similar to what happens when turning tightly in them. Try a tight turn in a 2 door jeep with full lockers on dry pavement sometime ;-) You get to enjoy both the front and rear skipping big time.
What I think is happening with the E63S is similar in that the inside tire is turning a smaller radius than the outer tire so needs to turn at a different rate, it's also turned at a tighter angle and it almost feels as if it's a combination of the tire being pushed forward at the same time as rotationally skipping.
You can feel it to some degree on dry pavement too, but maybe there's enough grip on warm dry pavement to force the differential to slip enough to absorb the difference till you straighten the wheels.
Back home in San Diego, I notice that the rear skips when I turn out of my office in the evenings even in comfort mode when the drive train is still cold. It's a hard right and the inside tire slips a couple of times as I'm straightening out even though I'm not stepping on the throttle that hard.

The other concern of course is how much this will wear the tyres?

i have an ams tune therefore make more hp. And torque at the wheels than a stock w213 amg and they handle fine ... hook up and hold me in the turns very well ... no wheel hop and actually decent in snow

summer tires are for certain temps... if they are wheel hopping then they aren't safe in that temp to drive and you should switch to all season or winter tires for your and other drivers' safety
