For months now i've been surfing the net trying to fix my e60 PDC. My friend diagnosed me that the front passenger pdc is faulty, so i ordered a new one. Turns out the sensor is not faulty, rather any sensor i put in that spot is not working (it doeant click, while all other sensors do). Is it possible that the passanger middle sensor is faulty even if it is clicking? So ive eliminated the sensor faultyines. Also the wires are in good shape and its unlikley a wire broke somwhere in the car. I've dismantled my headlight 3 times now. Im do not own a diagnostic. How can i check is my module faulty before i buy a new one?
