This happened 3 times in like the last ten days . Out of no where the engine seems to turn off and I get a message reading esc see owners manual . I have to pull over and restart the car , after that it's fine . Seems to be happening since I put my new wheels on . Could it be that the design of the wheel doesn't allow enough air to cool the brakes down ?

Is the overall diameter of the new wheel/tire unit essentially the same as the old?

Yea pretty much . Also I should add that the first two times were in tiptronic while in sport mode , this last tome however was in d while in comfort . My dealership re-adapted my second into third gear ratio recently as well .

that happens alot on cars with a ECU upgrade when the timing is advanced too far, it was posted alot on here in the AMG sections, alot of C63 guys had that happen and a few of us too. If you dont have an ECU update hit the dealer up if your under warranty. The computer keeps track of those errors and they can go back and see what codes popped up or what happended

I have a ecu tune , should I send it in to be reflashed

Im gonna guess and say u have the powerchip tune, thats the one I read about that this problem happens to. Most go back to stock or get a diff tune. I had OE tune on last car w no probs for 3 years and now brabus tune w no probs at all

I have a powerchip tune for about 2 years and I haven't had that problem.

I have to assume the dealership re adapting my 2-3 gear change effected my tune . Can I reset the ecu myself and then have it reflashed ir do I need the dealership to reset it. ?
