I had my DME cleared out for coding the BMW Electronic Performance Steering Wheel. I couldn't get the wheel to work with DCT. When I went in to uninstall the PSW, I didn't install one of the pins correctly. My M3 started doing all kinds of weird things, such as the wind shield wipers would not stop and I couldn't use any diagnostic tools because nothing could recognize the DME. The other hard part was contacting G-Power. I now have my G-Power SW so anytime the dealership clears out my DME, I can get the SW in the car again without contacting G-Power.
