Hello together, as I have seen in a few articles, there seems to be a fundamental problem with the lamp test. With me come with main display permanently messages when flashing “brake leucts defective” and with every braking process!!!! / “blink lamp defective”. It is annoying huge. A few times the trigger was a lamp of the license plate light which then led to the temporary healing of the error message for a few weeks. hten has already contributed to temporary healing. But I don’t want to replace whole incandescent lamps every 3 weeks. In the forum I have read from various attempts to clean all contacts and to install new mass cables,… Honestly, I don’t really want to lay new mass connections. Does anyone know if you can’t just disable the function of the lamp test? And if so how? Because actually this function is quite useless. If a flasher or fader ch is broken, I actually get it so promptly with.. Best regards MYK975
