GL320 Bluetec
Hello, I have had my Bluetec emmesions update and suddenly my GL320 turns over but won't start. The cooling fan then comes on full blast for about 30 seconds and then shuts off. My old scanner says fault in communication with ecu. Any suggestions? I am not sure if the ecu is covered on the blutec warranty. Thanks! Tim

Otherwise... and maybe others can say with more/less certainty/clarification... you may be looking a damaged (water?) SAM module.

Either way, have Mercedes read your codes, there is no fee.
Good luck, and be sure to update us on what transpired.

I used a different scanner on my gl320 and it says 11B100 component M3(fuel pump has open circuit and also component B76/1 condensation sensor for fuel filter with heating element has an internal fault. Could this just be a fuse or relay?
