2007 W164 ML500 front seats not working
 

Hello everyone, and thank you for any and all help you can give me, i own a 2007 ML500 ,vin WDC1641752A222536
for some reason i could never reset my service schedule, eventually it got the better of me, and a freind of mine had access to a MB star Scan tool, so we set about resetting the service schedule, not sure what happened but we ended loosing communication with the Gateway, basically wiped it out, now no indicators, brake lights and other weird things happening, so off to mercedes it goes to be reflashed, all good, till i pick it up from my mates, and i find out now the front seats dont work, and the sterring column wont move either, any ideas of what might be going on???
