Removing the steering wheel and restoring the loop airbag Passat b4
After replacing the steering wheel boot to the steering rack, I discovered that the airbag light came on. In the course of eliminating the error, I remembered that after removing the steering wheel cross, I did not fix the steering wheel, but turned it a few turns. I heard a click in the steering wheel, I guessed that it had cut off the airbag train. When I began to troubleshoot, I decided to make a small photo report, it may be useful to someone. Sori for the quality, filmed on the phone.
First, remove the terminals from the battery (battery).
With an asterisk, unscrew the two captive bolts from the back of the steering wheel that secure the airbag.
Disconnect the loop from the pillow by disconnecting the red chip. Just detach it carefully, it can be removed very easily (prying it off with a screwdriver).
This is what a disabled pillow looks like.
Next, remove the plastic sheathing from below under the steering wheel, which is attached with two self-tapping screws. Disconnect the white chip (end of the train).
We unscrew the steering wheel with the head by 24.
This is how the removed steering wheel looks from the back, where the train (airbag contact ring) is located.
We unscrew the three Phillips screws that secure the airbag slip ring and disconnect the signal chip.
Video (click to play).
Disconnect the plastic latches, the ring is divided into two parts.
And now she found the reason. Loop break. The train broke off at the point where it exited the ring. There are only two copper strips (conductor) in the loop.
So that the train does not unwind and for the convenience of work, I wound it with electrical tape.
Next, we cut off the surfacing at the exit point of the loop and clean the loop. It is better to clean the loop with a heated soldering iron. At first I cleaned the train with a scalpel, but this turned out to be not very effective, because the scalpel removed the copper layer, and it is very thin there. That is why I heated it up with a soldering iron, the insulation is easily removed and the copper layer is not disturbed. Well, now we are soldering. This is how it happened. At the junction, I glued the train to the wall with superglue.
I sealed the seam with silicone.
Let it cool and check the loop with a tester. At first I was surprised because he was short-circuiting (closing), but the reason is in the white chip, when it is disconnected, the contacts in it are closed among themselves, and open when the chip is connected.
Putting everything together in reverse order. Collecting everything completely. So the error did not disappear (the airbag accident light is on). Don't worry, this is normal. The error can only be erased with a diagnostic cable (VCDS, AVTOadapter, VAG-Com) and no disconnection of the battery terminals, as some write.
Attention . When entering the airbag controller (with the VAG-Com program), read carefully.

Found 2 errors: 1. Airbag chain break. 2. Weak supply voltage to the airbag. After erasing, we shout: "Hurray, everything worked." If you have any questions, ask.

Then we move the pillow from the steering wheel and turn the steering wheel one hundred and eighty degrees, on the other side, doing a similar operation.
So, these steering wheels are of 2 types for our cars, or rather, with two options for a set of buttons:
