Check your coolant tank for leaks. Sounds like bad coils based on my prior experience. Do you know how many miles it's been since your last plug and coil change? If its been more than 30k than it could likely be that. If the car is running inconsistently, I would always look at coils first based on my experience with the S63. My F10 M5, F85 and E70 X5M all did this same exact thing and were all remedied with new coils. Scan the car for misfires, it will likely be on one bank at this point, swap the coil from misfiring cylinder with one from a working cylinder and clear the codes. Go for a drive and see if the issue follows the coil to a new bank.
Edit are you sure it shifting into neutral and not in limp mode? |
