ML320 CDI transmission problems
My new ML 320 CDI has been in the dealer's shop for over a month. The car ran fine until one evening I got in it and there was an error message saying "drive to workshop without shifting gears". The next day there were other messages about airbag sensor failure and glow plug relay etc. The glow plug indicator would not come on and the car would not start. It was towed to the dealer where it has been ever since.
They have replaced numerous electronic modules for the transmission, plus other parts including oil pressure sensor etc. They have had MB technical support helping but the bottom line is they don't know what the problem is.
The dealership has been good about getting me a loaner and keeping me up to date.
Has anyone had similar problems?
Canada has no Lemon law but there is some precedence for buyback and my situation seems to qualify. Anyone had any experience in this area?

ML350, BMW525
I had the same problem with my 06 ML350. It was stuck in the drive gear and had the same message " drive to work shop...etc" The dealer state it was a faulty shifting module that had to be replaced, i have also posted on this forum. I continue to have other problems with my ML350, it been in/out of the dealer for over 44 days all together with other numerous issues and repair. I also bought my ML new from the dealer. Best of luck to you and hope they can fix yours.

ML 320 cdi tranmission problems
Sorry for the tardy reply. The latest:
The dealership is still trying to isolate the cause however they have now replaced all electrical components related to transmission, fuel system, and as of yesterday, climate control. There is a suggestion that the car was either boosted improperly (polarity reversed) or struck by lightning. I have never boosted the car and the weather was fine the day the problem happened.
The dealership has been excellent but alas I am still without the vehicle. Mercedes Canada are now involved and they have also been quite responsive and good to deal with.
I am pursuing options to get the car replaced so we will see how that goes.

transmission isues
I have a 2007 ml 320cdi.
The problem started initially with out of the blue the car started to rev erratcially and the transmission wouldnt kick down. When I parked the car it would reset. No the car will not go above 2000 RPM when in D, you have to go up through the gears with the paddles to get above 2000 RPM and drive like a manual
