- Jeep Commander CRD 3.0 2007 (Powered by Mercedes OM642)
Hi all
I've been having an issue with my Jeep Commander CRD 3.0 2007 powered with Mercedes OM642.
I was having some difficulties to start the engine first in the morning - since I have changed the glow plug and module 6 months I wasn't worried about those until this point.
So I did test all the fuel injectors and I noticed that 3 of them were returning too much fuel and I replace it - BTW I did not code the new fuel injectors.
The issue persists so I did change the crankshaft sensor, camshaft sensor and fuel regulator.
I did check the ground wire close to the fuel filter - I did not notice anything wrong with that.
I use the JScan app and noticed that I had errors in all the 6 glow plugs - I've replaced the glow plug module and cleared all the errors and nothing changed - so apparently the issue wasn't with the glow plug module.
I've bought a new set of glow plugs - I've tested them before with glow plug tester tool and they were fine.
Just after installing the new glow plugs I continue to have issues to start the engine - check for errors and all 6 glow plugs again - removed the glow plug and test with the tool and they're all dead.
I've tested again changing only one glow plug and right after I start the engine the glow plug dies.
What is causing a short circuit in the glow plugs maybe?
Thanks
