So after coding my 335i for the digital speed and digital speed correction off, my friend wanted it done too.

I went over to his house and we started, I told him to hook up car to charger. I started up my VM and was showing him how it all works and stuff this was about 15-20 minutes or so. I then started doing the actual coding. Some strange things were happening like random dinging and the hazard center button lighting. I finished with the coding and double checked the change. Everything was good.

I went to disconnect the charger and unbeknownst to me my friend had connected the negative terminal to the strut tower screw instead of the silver post!!!! The negative connection clamp was very hot.... we disconnected it for a bit to cool off. Then we actually hooked it up correctly and charged it for about an hour.

At this point we are getting ready to take it for a test drive and noticed the comfort access was not working. Then we notice a bunch of other stuff..windows, locks, instrument gauge lights, window button lights, turn signals, angel eyes...

Car does start... and shows the digital speed so the coding worked. We drove it around. Car drives ok but clearly something broke. Did we brick his FRM with the charger hooked up wrong/low battery?

I did load up rheingold and the FRM shows "ecu not responding" status. I told him its probably fried based on other posts I have seen on here. Is there anything we can try before sending him home to source a FRM?

That's what I was thinking. Man that sucks. He's actually taking it pretty good. He's bitching more about the turn signals being out.. the other stuff he could deal with until its fixed.

Yea I've been looking at the FRM3 resurrection thread. Someone posted in there that a bulletin just came out about BMW extending the warranty to 8 year 125k miles... So he's got 2 choices it seems. Pay for the equipment to try and re-flash it, pay someone to do it... or take off all his equipment (jb4 and stuff) and take it to dealership to see if they will honor the extended warranty on the module and hope they don't bitch about having angel eyes and boost guage wired in. They might say it was due to that (electrically) and not cover it or something. Never know.

I might PM you to inquire about your services.
