When this CAN wire shorts out, this can affect all modules on that CAN circuit including engine, trans, ISM, presafe etc. I am not on here a lot so I will try to help out asap My A 200 just stops without power and gives me the above messages.
It is very very dangerous and NOT what is expected from a Mercedes. A software upgrade does not work and the dealer battles to find a solution. same thing as here: she would kill the engine and crank it back up - no more issues. the wiring harness, because of location, was being worn through.
There has been some wiring issues near the high pressure pump.
There are some sharp edges and the wiring harness can rub through.
Update: The dealer had the car all day Thursday and half a day Friday but could not find the cause of the power loss.
Their head technician was on vacation this week so they scheduled the car to be brought back in next Wednesday for more diagnostic analysis. They agree with me that it should never lose power to the point of being unsafe on the road.
The service department just called to tell me that after having my GL for 4 days they were unable to diagnose and resolve the issue. They sent a diagnostic report to MB corporate head quarters in New Jersey and after a day of looking it over they replied that they could not offer any additional suggestions for the technician.So they are returning the car and want me to drive it until it happens again and then call them. Not the easiest of solutions but I know that corporate MB is pretty tough on what the service techs are allowed to do if they cannot physically see evidence of the issue.To which I have always wanted to say...."you think I would make this up in order that I can make life miserable for myself? I had a similar message, intermittently, "distronic plus inactive." after a couple, "no error codes found' from the dealer, I took it in while it desplayed the fault and had them scan it WITHOUT restarting the vehicle so that they could scan the vehicle with the fault active. Is this the problem/error what caused mercedes to allow you to trade your vehicle in for the 2014 GL550?Some times you will not have any fault codes for the check engine light and that is why it can be hard to diagnose.When this CAN wire shorts out, this can affect all modules on that CAN circuit including engine, trans, ISM, presafe etc. I am not on here a lot so I will try to help out asap OK guys heres an update that could help out but this is a little more common the the ML166.
The other aspects would most likely be sensor realted, but tied in with this "no power" sensation, it could be a program issue.
