So I have a 2012 335is, 57k, 6spd MT swap, M3 LSD, FBO, MHD 2+ only, running on E30....and now I killed the car trying to do the DP fix to pass emissions in RI. Simple plug and play....easy peasy. Car started after installing DP fix and flashing to stock map so the otherwise hidden CEL would come back on to run the correct FTP drive cycle and get thru all the o2 and evap b.s. in order to get an inspection sticker. Long story short, it went into limp mode (large half engine light with the lightning bolt) while doing the drive cycle. It was the middle of the night so I could complete the drive cycle without interference...and I was tired (and stupid). I pulled back in the driveway and wasnt thinking. Pulled out the smaller DME harness without taking off battery negative terminal!! Now I have a crank with no start, windshield wipers on without any way of turning them off(other than pulling fuse), and windows don't work(except by key fob down and up because I had coded that in with Protool) I have a shitload of codes from Protool. But MHD will not even communicate with DME.
