I've got 16 C63S with known electronic LSD and noticed weird thing on my driveway. While pooling in one of my rear tires end up being lifted of the ground and car wouldn't move. Tried to switch to sport mode by disengaging traction nanny and it didn't do anything. Makes me think if it'd be better just to go with regular C63 equipped with mechanical LSD that in theory should put power on both wheels don't you think?

Give it some gas it will lock up and get you up the drive way. Otherwise get it checked by your dealer if it's letting the wheel off the ground spin uselessly. I too get a wheel off the ground going into the garage from off the street and you can feel the torque transfer when it locks and bites.

Before this I had a BMW 335 with an open diff. I had a Quafe mechanical LSD installed and that was so much better than the stock set up. I used to go up the same incline with that car and while it had a bit more suspension travel than the C63S, I can tell you the electronic diff is better in virtually all driving situations including the wheelie one you are describing. The car does a bit better in the wet too.

My car gets stuck on my steep driveway all the time =) car is so stiff. I think my neighbors must be very confused

Problem is the suspension barely has any travel. It is rocks stiff especially the sedan

I have the same issue here with the mechanical differential on the C63. One wheel gets lifted, and when i hit the gas, i get a grinding noise and the car moves. I turned off the traction completely, and the noise is significantly down, but there is still something grinding. It almost sounds like the car is bottoming out, but there is clearance. any idea idea if a grinding noise is normal operation for the LSD? or is this something to be worried about?!?
