2015 c4 picasso rear right speed sensor

[Spoonhead]

Hello, I've been charged by my parents to help find a solution they have with there car

It's a 15 c4 picasso.

If they hit a bump then several faults come up "Abs/ESR fault along with hill start, parking brake"

They took it to they local garage and had the sensor changed but didn't fix it.

I did a bit looking on here and other places and since changing the sensor didn't help it has to be further back in the chain.

I'm basically trying to find the correct part number for the harness the speed sensor connects to.

A very helpful post on here for someone who was a similar to this had a wire diagram in it called "Wiring Harness 80 AR SP"

When I Google that I can't find anything so is there another name or part number that I could look up?

Most likely the wire has rubbed / rotted through on the corrugated trunking, just repair the sections that are suspect.
