When i want to use CC i get the error Bleep and SERVICE on screen.

I already replaced the brake sensor and i red that the LIM 0 REG button on the steeringwheel also can give an error message so i scrolled hard trough the buttons but they seem to make good contact.

I plugged my car in the garage in the computer and the error message says there is something wrong in the wiring from the brake sensor.

And it also says there is a faulty cable on the inner rear right parking sensor.

Can anyone point me in the right direction on that to do now? Can i reach the rear parking sensor trough only dissasamble the small plastic rear pannel? Instead of removing the whole rear bumper.

Sorry for my bad english, im from the Netherlands.

Well that was fast, but i just drove home and pushed a few time hard on the LIM 0 REG scroll wheel in the steering wheel and voila Cruisecontrol worked.
I had to brake so the WHOOOOHOOO moment didn't last for very long, but on a straight road it turned on again and immediately stoped with the *BLEEP and SERVICE message.

So i thought lets scroll trough the modes again a few times and indeed it worked again, this time for a lot longer until i had to brake.

I'm so happy. i only need to know now how the take the connectors of the wheel so i can clean the contacts. I must be some dirty contacts that causes the failure.

What do u guys think?

Spray electrical contact cleaner in there & rotate the wheel a few times.
