How to repair a door lock on a BMW F07

Left rear door lock jammed. I raise the vertical locking pin of the lock, it does not rise!

Outside the door handle, of course, rises, but does not open the door.

From the cabin, the handle does not even want to move away (passenger).

The stump is clear that you need to remove the door trim and poke around in it. Yes, but HOW to remove the trim if the door does not open??

Or is there another easy way? After all, I am not the first in the history of motorists to find myself in such a hopeless situation!

Not in the sink, but under the snow in an open parking lot.

The bottom line is that when you press the central lock and hold the locking pin, you don't feel any pull, as if the lock actuator (solenoid) is dead.

But again, this looks like a mechanical problem, not an electrical one. Mechanical wedge stuck, IMHO ..

Thanks for your reply!

We already have a positive temperature, so the current frost version is no longer needed. But there may be consequences.

Well, I will apply different methods to increase its anti-vandal effect.

Solved a problem.

I am writing because it seems to be necessary to report, but I can’t really say anything!

In general, foolishly began to pull the handle of the hall and the front door at the same time. OPEN My first thought was "how did this happen?" Also, the locking pin has never been lifted.

The first thought was immediately replaced by another: "Don't try to slam the door." The second time may not work either.

He took off the carcass (without blood) and began to see what was happening. The assholes aren't going anywhere. Stuck and all.

It should be added here that during the operation of the central lock, the left rear solenoid did not react in any way. I mean not at all. No attempt to move. I removed the terminal from it, connected the tester - the voltage comes. So the lock solenoid is broken, I decided. Again, like a fool, he began to pull him from side to side, but to no avail. I took it and cut out a plastic rod for it, thereby freeing all the door lock mechanics from the solenoid. The door worked.

Bottom line: I'm going to put in a new central locking solenoid.

Conclusion: at the slightest failure of the central lock, check the solenoids for a quick gasket! It is unlikely that you will be able to open a stuck door, as I did. I'm sure I'm lucky!

Thanks to all who responded!

#18 Front door lock repair

 

Hi!

Something I completely relaxed and filled out the BZ, although there are already a damn dozen posts of information

I will not be naughty, I will write a post about the story that happened to the shark this winter. Maybe someone will be useful.

And so it was.

Continuing with the work of installing Harman to stock, i.e. installing speaker grilles on the front doors, I removed the trim from the front doors and, like a true jack of all trades, did something with the lock, at least I thought so, because . SUDDENLY stopped working in normal mode, the lock of the right front door. The door opened and closed normally, the closer worked, but the lock did not close with the key and with the interior button as well. In order for the lock to close, it was necessary to manually lower the float, and to open the door, respectively, it was necessary to pull the handle. I didn’t really tense up, because I mostly drive alone, and then, according to Murphy’s laws, some passengers became more active)) Who, again, according to this Murphy’s law, everyone wanted to sit in front, and I had to open the door for them. And I realized that enough to endure, for now)

And, having stocked up on beer, my friend and I started a derban)

1. Armed with a combat tool with aliexpress, remove the door trim.

2. Gently bend the soundproofing, I used a clerical knife for this.

And then we were waiting for a catch that no one expected)

The lock, such a thing, assembled, without toothed bolts, on rivets *facepalm*. Thank you BMW AG for our happy childhood)

Che, we didn’t do current with him, breathed, rubbed like Aladdin’s lamp, tried to find a way to painlessly disassemble it, but to no avail) And then, after our manipulations, I noticed that the float began to walk smoothly. With a beating heart, I run to connect the lock, I press the signal button, voila, the lock works!

But my happiness was short-lived))))) A week later, he stopped working again, and it became clear that surgery was indispensable.

Weekend, garage pickup, repeat manipulations 1-3.

To disassemble the lock, it is necessary to remove the metal plate, which is held on the welded rod.

And then it was not clear, everything is in order with the mechanism, but what is the problem? The lock is clearly working, the float is moving, but it is clear that something is interfering with it, moreover, of a mechanical nature. But everything turned out to be simple. When we assembled the castle, it turned out that the plastic box, my God, who would have thought, is not ideal)

The photo shows that this plastic debris is too tight on the mechanism, and a plastic splinter gets stuck there. We worked with the file, inserted it and voila, everything works.

We press the rod and collect it back.

But there is no fly in the ointment without a fly in the ointment, having picked up the lock and the door, we did not check, closed it, and there her mother flew out of the wire))) The door was tightly closed)

But with the help of a skewer and a kind of mother, they opened it from the side of the windowsill. So, happy ending

This entertaining reading has come to an end, thank you all, we are working =)
