Hi Toni

You need a diagnostic scan, my guess is the EWS is faulty and not allowing the key to program it may just need reprogramming it's self or a new EWS fitted and matched to the DDE

The reason I said don't dismiss the Key is as Phillip says a key that has been tampered with can cause all sorts of issues

Stu on here had to fit a new EWS and reprogram it to his chassis and DDE plus programming new keys to fix the problem

If you can't DIY you need the help of someone with BMW Diagnostic capability

The car starts normally with the key. And when I turn the key in the door, sometimes all the doors unlock, but very rarely. And also the only door that locks when you turn the key in the driver's door is only the driver's door.

But once every month the doors are locked and the windows open completely by themselves.

The problem is therefore unlikely to be the EWS

Morning Toni

First dont dismiss the Key if it starts the car it is being charged when it's in the ignition. If it isn't communicating with the EWS or there is a fault with the EWS your issue could be in that area.

Dave

The doors open from the lock by themselves and the windows open by themselves at the same time during the night.

takes place for 1 month.
And the key buttons are not pressed once.
the key is up at night on my computer desk

The doors open from the lock and the windows open about 1-2 times a month by themselves.

I've been explaining this for 2-3 months now, but I can't find the fault myself.
There is no fault code coming from this in any way, or at least I didn't notice that there was a fault code.
Now the help would be very useful.

Could, for example, the micro-switch of the driver's door lock do that?
Or as it was said somewhere that the SGM module could solve this problem?
However, the SGM Module is green in the ISTA module tree.

Before When someone says that they are sure that the button is not pressed at the bottom, then:
The key has run out of battery. In other words, nothing happens from the button on the key.

As I explained, I lock the doors from inside the car with the button on the center console and lock the driver's door from the door.
In addition, I make it a point to bring the key inside and check that the doors are locked when the key is on the table in my room.
And yet in the morning the doors are unlocked and the windows open

What could do this problem.?

Fault codes:

I've been researching this for many months now and it seems like it's giving me gray hair. K-CAN Line Fault is still on.

I have used every module of the rear container and the modules of the seats as well. But K-CAN Line Fault does not lose anything.

 

Somewhere it is said that the SGM module could also solve this problem. Does it hold true?

However, the ISTA module in the tree has the SGM module in green.

 

What would you do next here?

Should we ask a Finnish person to look at something with an oscilloscope

I do know that there is a problem on the MOST bus side.
The problem is on whether the TEL/MULF is in place or not.
