Had the EGR deleted before and the related codes were turned off in the tune. Now I decided to fully delete the EGR, a few days later the cel came on with the Code P0540 grid heater. Could this be related to the missing EGR valve?
There might be a fault in the wiring harness or the grid heater itself. Did you tune it yourself?
No Rob at Atp did, but that was before I deleted the EGR completly. I had only the bocker plate back then.
Just wanted to make sure its not related, before I waste time to check the grid and wiring...
Sorry to bring this one back.... I was wondering if the ground fixed your problem. I'm having the same issue.
Thanks in advance.
How did you end up grounding the heater? I have this EXACT same problem and cant get get the CEL to go off.Yes better ground fixed it.
