Hello Elchgemeinde. If you had a question about the encoder for the lighting range regulation (charge dependent) for Xenon lighting. The reason for my question is this: Drive an XC90 with level regulation and have no problem with the lighting system, but I suspect that this sensor/donor could have a combination function for the lighting range regulation and could also be responsible for the load-dependent braking force distribution on the rear axle. Only no one could help me so far (large shoulder shrugs also at the friendly) Also the circuit plan allows no conclusions in this regard. The fact is that the rear brake discs in normal operation (without constantly driving around with the half house stand in the area) do not freebrake and just rot over time. So now you are on it !!!!!!!
