Hello dear ones, I had already created a thread ( click ) some time ago, but everything was not so closely observed yet and in the end I also lost the topic. Now on vacation we went on the nerve, but the problem: every time you put on the handbrake and have the light on (no matter if standlight or glare) both the AI lighting as well as the lighting of the climate part goes out. I made some observations that I would like to give you observation 1: The handbrake is NOT attracted, but the dimming switch is on full and full or dimming light and the ignition is only on 2 (motor NOT started). There is to be observed that only oil, motor, ABS and SRS lamp are on (at the end it was only oil, as the others went out as usual). If I take dimming switch to zero, all lamps are normal. Also, when the light is off. I then pull the handbrake and the DS is on full, the illumination of climate and AI goes off and all control lamps are on again. Observation 2: Ignition is on I, the DS is on full and stand light is on. Then one looks slightly shimmering the park and oil lamp. On dipped light, however, everything is off. But if I take off the handbrake when I stand still, the shimmering of the lamps is off and everything is off. Observation 3: When you turn on the light, in the display from our radio (SC-805, but in gray) the light is off and com It’s getting brighter and brighter again (but that’s all within 1-2 seconds) Observation 4: The P sign always lights up during the ride when we’re driving without light. If we turn on the light and the DS is full, the sign is off and all other lamps. Provided it’s all right. In order to fix the problem, we just have to turn off the car and then turn it on again. The problem is already fixed. But that can’t be the solution. It is worth noting that switches such as INFO, or the light switch itself and also the radio remain illuminated. So concerning “only” AI and climate go out with the light. I hope I have been able to present everything a little understandable and hope for a quick solution. If I should look further things: by Sunday the moose is available to me at the door and I will try to comply with everything as soon as possible.
