Hi,

I have a 2017 F36 and the PDC / park assist are not working.

I have 4 fault codes:

Ultrasonic sensor rear outer left, signal line: Line diconnection

(Other 3 are: rear left, rear side right, rear outer right).


The car has park assist, so has 6 rear sensors.

I've checked that all sensors are plugged in and did the "hearing" test and can hear a ticking for every sensor?

Is it that 4 sensors need replacing? Someone did scuff my rear bumper (outer right) but the sensor looks ok.

Anyone got an idea to what is wrong, how to fix?

Many thanks
