Hi
I have always had the common fault with my parking sensors that when they get wet they don’t work but this winter they stopped.
I checked over the loom at the front and have now changed all the sensors over but they still don’t work.
I have now read that once changed they would need commissioning to the car. Is this true and if so is there any one of you kind guys with the correct equipment that could help me out with this.

Many thanks MY06 FL1 TD4 2 door red (gone)

I would have assumed that if they were already fitted and working at one point, then just changing the sensors and the wiring wouldn't necessitate the need to have the CCF modified, after all, modifying the CCF only turns an option on or off and in your case the option should be set to ON.

When you took of the old wiring did you notice any breaks or chafing at all, may be worth testing with a multi meter if you still have it to see if there is continuity at each end of the connections, it may be that your issue lies elsewhere
