Bulb check light without any light off

[lironeden]

Hi, my bulb check error suddenly appeared one week ago. I didn't do anything to the lights in my car, not any modification.
The error apperas only when I press on the brake, but there is not any faulty brake light, everything works as it should.
I tried to replace the brake bulbs anyway but the error still consists.
I scanned with my vcds and it says there aren't any errors...
Can someone help me with that?

If you have replaced any of your bulbs with LED then this can cause it. I replaced my reversing light with an LED one and it started showing a build warning and causing the left indicators to speed up (as if one has blown) making me think there was a problem with the indicators rather than the reversing light.

If not it maybe a faulty connection to one of the lights and when the brake light are powered one of the other rear lights are not sending the correct signal or response.

If you can I would disable the bulb checks one at a time and see if it stops after doing these.

Failing bulbs can show a warning light just before they go pop, believe it’s a high resistance that causes that. Change/swop one at a time till it goes away?
