Technical Rear right signal always on !

[decadurabolin]

I have a problem with my right signal, from the rear lights. It always stays on. Even if the car is moving or stopped and closed.
Any ideeas about this problem? Could it be BCU error?
And what's interresting, i have no error in the dashboard.

Thanks !

just sounds like a loose connection. take the unit out, clean the contacts and put it back.

also you wont get a error, the resistance will still be reading ok so it will know the bulb lights up. its when it dies and the circuit is broken it brings up the error

Unmounted the rear right bloc of lights, and nothing.
Cleaned with contact spray and nothing new.
The signal bulb is always on.
Any other ideeas about the problem?

sounds more like a stuck relay, im not sure which relay is the one for the right signal, hopefully someone will be able to point you in the correct direction.
its most likely stuck and probo needs replacement.

I think there is no separate relay for the indicators. It's an integrated function in the bodycomputer.

you sure, as when i put my indicators on i can hear a relay clicking!! im suprised if that is the case.
Another thing to check,
have you had any bulbs blow on the front on the same side?
if so it could be that there could be a problem there (even on the front) and it could be sending a feed down the line to rear light.
i would check any previous work done first
