Helpful Extended Warranty Info
I called MB Customer Service and they verified that fact and called the dealer for me. I talked to the dealer rep and they then agreed. The diagnostic fee would be charged ONLY if the repair was not a warranty covered repair.
Read your extended warranty contract and be prepared to argue against the diagnostic fee if you have a warranty claim.
If the repair is not covered, then you will pay a diag fee.
Another way to think of this:
If you suspect a broken part, you come in to have it diagnosed. There is no broken part to be found, therefore there is no warranty claim to be made. In this case, you are paying for the labor hours to discover whether or not there was a problem in the first place.
Glad you got it worked out, though!




The warranty would cover if the rust was due the roof defect, but dealer wanted $1200 retainer for headliner removal and investigation.
We decided we can live with the dirt.
