2006 E320 CDI (DIESEL) NEED IGNITION WIRING DIAGRAM and ECU pinoiut description
I have a 2006 E320 CDI.
I am looking for the ignition system diagram as well as the ECU poinout description. I had another thread with no responses so it is probably easier to find an electrical diagram of the car.
My car has a diesel engine so the electrical diagram should have a preglow control module and glow plugs (no spark plugs).
I believe power is not getting to the ECU, so I would like to check the Harness connector that plugs into the ECU and see if there is power and if not, to trace it all the way to the source (preglow indicator light does not illuminate either). The ECU fuse is good. Scanner powers on but can communicate with ECU.
Regards,
Martin

I have a 2005 e320 cdi. New batteries ( aux + main ) alternator seems strong . This problem use to be much less intermittent but now almost all the time . No glow plug light comes on and car doesn’t try to start , can’t talk to ecu with scan tool .
Here is the weird part , jump starting the car with another car or a jumper pack that a tow truck driver would have would not allow me to start but I have a small lithium battery jump pack and this will allow me to start the car every time . When I first started seeing this problem I had searched through many forums and I had found another member that had bought the same pack and I gave it a try and it worked . I’m not sure what the difference between this jump pack and a car is but it’s the only thing that works . Any suggestions on where to look ?
