Mercedes E-Class goes into Park when slowing down
Hi guys I wonder if someone can help me out there I am having problems with my Mercedes E Class w212 when slowing down it just throws itself into Park with no warning lights or messages. It doesn't happen all the time it comes and goes I have had my main battery changed and had it programmed in and for a week I did not have a problem.

OK, but it may be there is a door switch that is out of adjustment making the car think a door is open while moving. If you have this happen again, take notice if the overhead lights come on at the same time the car goes into park. If so, the switch may need adjustment. If not, there must be other conditions that make the car think it is in a door open condition, and there may be other sensors that cause it to go into park. Maybe some of the MB experts on here have an idea what is causing this. It can't be good for the transmission to have this happen often. Good luck with the diagnosis.

If VIN is below A776831 see attached bulletin ignition switch may be faulty.

There have been other posters with the same issue. I think this is definitely the cause of your problem. I remember an MB tech on here stating this as the cause in another thread, but cannot find it now. Share this with your SA

I’m having the same problem with the car going into park. Should I just call the dealer and have them order the EIS and schedule a time to get it put in?
does the part have to come all the way from Germany?

Yesterday I had it plugged into a mobile diagnostic machine and the man at the workshop drove it and it happened whilst he was driving so he drove back to the garage and we had a fault saying that there is a problem with the radar control unit not communicating.

Parktronic and Distronic have nothing to do with this. The lack of communication is the key sensor.

Somewhat off topic but related...is it possible to program the car to NOT go into park mode when opening door with a STAR DAS system? I like to sometimes stick my head out when parking in reverse and have a tendency to forget that the car will go into park mode when door is opened at low speed. I'm sure the transmission doesn't like it either.

Any guesses as to the approximate cost for the dealer to replace the EIS? Also I just bought the car week before last so I have the bill of sale but not state registration or title yet (takes 3-4 weeks). Is this gonna be a problem???

If vehicle is within VIN range request MBUSA goodwill replacement arguing EIS installed @ production is defective per bulletin.

There is no reprogramming this EIS. It's a built in safefty so that when you remove the key from the switch, it will automatically put the transmission into park.
