Door won't open when cold!!
Anyone had experienced any problems with the doors when it's cold (<32 F). When I wash the car and leave it parked outside, temperature is less than 15 F and I try to open the rear passenger side door next morning and It won’t open from outside or form inside... This happened to me for the 5th time now this morning. I had 2 dealers checked it when it happened first time and one said “expect anything goofy from this car when it’s cold”. The other dealer couldn’t replicate issue, they checked the door for codes and they put WD40 on the handle and latch.
Any ideas?
Thank you very much.




After washing the car, take some towels, open the doors and hand dry the door seals. If the next morning the doors open as they should, you'll know that water isn't draining properly......which if it is, I don't see how that's correctable.

My current problem of the week with my E550C is Keyless Go failure, so I have
some sympathy with you. As goofy as it sounds, their comment is closer to the
truth than we would wish.
My Keyless Go fails when cold apparently due to a
battery voltage drop in the cold. They claim it is due to my "driving style":
short work - home trips which do not charge the battery properly.
So this low voltage shuts off my Keless GO!
Yet it works fine after I click the car open / locked with a key, and none of
my previous MB cars' Keless Go failed like that, and there is enough juice to
start and get all the systems to work as soon as I start the car.
And so they say the car "behaves as designed"....That may be the case but I
am sure it is not the way they meant it to behave. But no, "you have to get
used to it Sir!" A marvel of engineering!
What a load of crap that is!
Anyway back to your car:
Do I understand correctly: your power lock responds
to your hand on the handle but the handle will not open the door? This would
mean problems with the handle / latch.
If you do not hear the click when you reach for the handle (even without
touching it) and if the display on the speedometer says "key not detected"
then the problems with the Keyless Go. Which is your case?

If you wash the car make sure to wipe the water off handles really well.
Also, dirt might be an issue...
I have not experienced it since....
K-A, you are right, those cars should work as designed for extremely cold/hot weather conditions.
mg-e550: it happend after i had and fixed the dent... is it possibly linked to the door water drainage leaking in and freezing.
Thanks again.

Theoretically their tools could have hit some sensitive parts inside. I'm not sure where these sensitive parts would appear on a W212. Which exact area of the door was the dent fixed from?





Worst was in Virginia one winter when it would not start at all. Had it towed an dealer there replaced the regulator-no more problems, but two years later.
Local dealer had been adjusting the Bosch warm up regulator per BMW standards. They sold both makes and both had same regulator. Saab said do not adjust, but BMW had TSB on how to do it. He said Saab would not replace them as they did not consider them defective when received. So dealer was out cost of part and labor.
Regardless, multiple adjustments never got it right.
Good note was that the local dealer reimbursed me for the tow, parts and labor in Virginia.
So, yeah, you wold expect cars made in cold climates to really do well in mild winters. Of course, you would also expect Toyotas to not have acceleration and braking problems.
