first of all, sorry about the image quality i was working on the car until late.
Its an e46 - 2003 318i, with the n42b16 engine.
the car suddenly didnt start one day. No crank, not clicking. Nothing happens when i turn the key. I changed the fuel pump, checked ALL the fuses inside and outside, replaced the COMPLETE wiring, changed ALL the sensors. And when i say all, i mean literally everything.
- What i do know :
I can turn on the ignition, lock the doors with both keys, tried 4 different batteries, the alternator is new as well.
- when the ignition is on the yellow DSC light is on and will stay on. The handbrake light also stays on and the tempterature gauge will go straight to max in the red zone.
- my code reader and inpa can no longer communicate with the ECU. I just get an error message. I can communicate with the EWS and other modules.
UPDATE :
- So i took out the cluster this morning just to take it apart and double check and just for the “fun” of it i tried starting the car without the cluster and it started cranking. Just crank no start tho.
- i started disconnecting stuff one by one to try and start but nothing. I put the cluster back in hoping maybe now i can read codes but still no communication. However the car now at least cranks. The temp gauge still shoots straight to red and the DSC light is on as well.
- checked the fuel pressure and it is 0. I can hear the pump click but it wont prime so i believe its getting power but no signal from the DME.
- Took out the DME and gonna send it to a shop as soon as possible since Im losing sleep over this.
