I have searched around and not seen any answer to my issue. Has anyone managed to disable the "feature" where the car slams itself into park if you open the door while rolling? I open my door while reversing into my spot at work, while lining up for the car wash, and while checking side clearance in my driveway. I get that the shifter stalk thingy is non intuitive, but I feel like damaging my transmission over and over is a high price to protect against the outside chance that I get out of my car and wander off with it in gear.

I assume the dealer would consider it safety and not want to code it out, but was wondering if anyone who had STAR developer mode access could do so?

Anyone else as annoyed by this as I am?

 

I thought it wouldn't go into park unless the vehicle is at a full stop?!?

 

it will automatically shift to park if you open the door with a bright red dash warning just as he said. This issue has come up several times and no one has ever posted a way to defeat it. Sorry

 

Open the door, let it go into park, then while door is open, shift into R again.
I'll never forget the time a tech did that in the service bay with another customers car.......that sheit was so cringe worthy He also was in R trying to see where he was going.

 

Nice!! Mystery solved.

 

I hate that feature. One time I was coasting to a stop and opened the door to pull my safety belt that got caught in the door and before I knew what happened I almost left my front teeth on the steering wheel

 

I don't have a W212 and know nothing about them!

I had a 2016 GLC that did this and also used to do the same if the passenger door was opened before coming to a complete stop. After the first service at 12 months the car no longer did it. I mentioned it to the dealer at a later date and was told that an update had been applied at the first service and that may have changed the feature.

Probably worth enquiring about such an update from your dealer.

 

I don't want it to go into park in the first place, I know I can manipulate the lever after the fact, but this is a bug, not a feature as far as I'm concerned.

 

I'd have to agree. Why would MB want the car to shift into park when it's moving?

 

Someone probably got run over after forgetting to put the car I park...

 

I've seen footage of this happening on youtube

 

.
At least I now know a solution thanks to this thread.

 

Open the door while in drive, THEN shift into reverse.

You get roll away warning but you can drive.

I learned this last week, only had the car 2 weeks tho.

 

Here is why

 

I've seen that one too, and the guy honking his horn seemed like a real fawkwad.......the older man didn't have to get out of his car though just to shake his fist, he could have gotten really hurt.

 

Weird that this 164 didn't engage park. I remember ours doing that and I had an E70 X5 that did that as well.

 

yikes. the guy who honked was in the wrong on this one imo, but everyone likes to rag on "mercedes" drivers because they are "entitled"

 

Hi did you try to disengage the door sensor

 

I couldn't agree more!. Just bought a 2016 C300. On other cars I've opened my doors while moving to let mosquitos or bees out, or even to listen for sounds like a bolt or a rock stuck in my tires. What happens if you were to do this at 20 or more MPH?? I would like to disable this 'safety' feature.

 

I thought it wouldn't go into park unless the vehicle is at a full stop?!?

 

I sold my W212 a while ago but if IIRC, you can't shift into park while the car is moving.
However, if you open the door, it immediately slams the car into park.

 

It will quickly come to a full stop.

 

Yup, very abruptly too and you heard a very loud noise sounds scary like something broke in the transmission. Had this experience in my friend's E 400 in the passenger seat.

 

If you watch the shift indicator on the IC you will see what gears the transmission will "allow" given current conditions. For example, reverse is unavailable (as is park) when you're rolling forward at 60mph. When you're going slowly, park becomes available at a defined speed - maybe 5mph? I haven't paid enough attention to know the exact speed. At any rate, I wonder if that defined speed at which Park is available can be redefined to "zero", thus eliminating the possibility of the car putting itself into park when it is rolling.

 

Yes that is around the speed as I know specifically (again my friend's car) he compliant that he pressed the Park button my accident at speeds below 10 KM/hr and the parking pawl starts ticking to a stop.

I also made this same mistake on a previous MB again with the column shifter. I forgot how I made such a mistake but it must be a bad reason as why was I touching the column shifter stalk when driving.
