Parking sensor fault 159, help!
I have a fault with my parking sensor on my 159.
When I start up and put it in reverse I get a long beep and then in the display "parking assistance not available"
I had had a go at it with a fault reader and it said circuit shortage or something like that. I understood that there was a problem with the power supply. It did not say if there was a specific sensor.
I looked at the wires to the front sensors first, and could not find anything that could look like a fault.
And when I disconnected the connector to the front set there was no difference.
But when I disconnected the connector to the sensors at the rear bumper I got fault code for all the rear sensors, and the original "power shortage" fault disappeared.
So I can conclude that the fault is with one of the rear sensors?
Are there some typical places I can look for a fault?
And do the rear bumper need to come of to get access?
