2007 E550 4Matic
 

Please Help

My E550 died the other day and it wont crank over. It restarted 3 times and ran for only short periods before shutting off and now nothing. It would only start after the fan shut off. Temperature gauge was blank until the fan stopped. Then it would show normal temp and I could cycle the key and start it. Now nothing.

I can crank the engine over by hand and it has 4 current and 114 stored codes.

The 4 current codes are, Left marker light, rear SAM circuit 30 under voltage, in car temp sensor and specified/actual configuration of most Ring differs.

I have read that the ECM will cause the fan to go on high when there is no current present. The problem is that I don't have any codes in the ECM. It test fine and the stored codes are mostly under or over voltage. Tests have passed and I'm using a Maxsys scanner by Autel.

Please help as I don't want to get it towed 2 hrs to the stealership.
