Hello all, I bought a 2000 540i nonrunning(i know.., I know...) The previous owner took it to the dealership and decided he didn't want to put anymore money into it. The dealership found that it needed all sparkplugs, 1 ignition coil, thermostat, and new battery. Now it wouldn't start, they narrowed it down to the fact that the DME was not responding. "many modules had communications with the DME". The last thing they said was that they needed to "perform wire testing for power supply to DME". I asked a mechanic later and they verified it was getting power. When you plug a OBDII reader it wont make any communication. I'm leaning towards the DME being dead. i pulled it and it looks clean with no obvious coolant damage from the Thermostat. I have bought and replaced the battery. I have all the spark plugs and thermostat and ignittion coil but wanted to install it after I figured out why the DME wouldnt even acknowledge. A new one is 2000 from BMW and there are services online for 250 that repair bad ones. has anybody seen this before? Any help would be much appreciated.
