VW Bora: Ticking Sound & Tailgate Indicator Glowing After Rear Lamp Bulb Replacement

Question

Hello, after replacing the light bulb in the rear lamp, the indicator of the open tailgate started to glow. The tailgate can only be opened with the key. The interior lights and the light in the luggage compartment also do not work. There is a chirp under the steering column. With the door...

The place where the sound comes from is the comfort module.
It is mounted under the steering wheel. He is responsible for lighting the cabin and the boot.
It is diagnosable, so in order not to feel in the dark, you can connect to a computer.
Maybe it lacks weight or some power supply, or it is damaged.

Accidentally, the rear lamp bulb holder came into contact with the trunk lighting lamp hanging on the cable and shorted. This could be the cause. The luggage compartment lamp drops out of its mounting hole and makes contact with the tail lamp socket.

It cannot, and it is the cause. Check the fuses in the cabin and if they are good, then disassemble the comfort module because maybe something got burned in it from this short circuit.

I checked the fuses, I take out the one with the number 38, it does not tick, it is responsible for the glass, el lights, etc. if I connect it back, it still does not look like burned. I also checked the module from the outside, you can't see that there is something wrong with it, maybe some driver? I did not check the module thoroughly due to lack of time today. On the enclosed specification fuse number 38.

There are probably 5 power supplies from fuses for comfort.
The lamp in the trunk is controlled by the mass from the lock, the plus comes from the comfort module and the same plus goes to the cabin lighting.
This plus goes through the relay from the comfort module.
Show me what module you have.
Open it and see which relay is ticking because there will be at least two inside.

Hello, my module number is: 1J0959799Q (ON THE PICTURE) ticks.
I decided to replace it entirely. Today I am going for a module with the same number?

Should it stop humming after plugging it in, or only after adopting it? I am asking because before I buy the module I will connect it to the car.

grala1 · Answer

You put in the module and the lighting should work. There, only electric windows are set in the coding - two, four, etc. Lighting should work on each coding.
The encoding should be rewritten from the old one.

Pablorza · Answer

I connected 3 modules with the same number before buying and unfortunately it is not a damaged comfort module.
