Parking Sensors Issue? 2005 E60...

[Raymonndo]

Hello guys,

I'm sure you've heard it all but I've come to the forum to seek help.

Recently my E60 PDC failed which left me with no front and rear parking sensors.

Upon researching I've found methods to diagnose this issue in this case hearing the clicking on each sensor. I found the faulty one/two and replaced it. This worked.

After a short while it failed again but this time none of them clicked? So I replaced the PDC module to no avail but now I'm pretty stuck? I don't think 8 sensors can all go? Wiring?

Any clues/guidance?

Many thanks!
