Cruise control problem

[Gollings]

I've been having trouble with the cruise control on and off for about a year.

Symptoms started with the exclamation mark being displayed in the MFD when the cabin of the vehicle was hot (parked in the sun). After a few minutes of driving and a lot of the heat gone, the CC would work.

It started to get a lot worse last summer and I sent the car in to VW, who replaced the stalk. This didn't fix the problem so it went back and they replaced it again.

That didn't fix it either, but as the weather started to change and cool down, the problem went away.

Fast forward to today and it's worse than ever and will occasionally disengage if I drive over a bump in the road. Sometimes waggling the stalk around or pushing/pulling on the steering wheel will make it start working again but equally it won't.

I've scanned with VCDS and the only fault is Cruise Control: Implausible Signal. When I can I'll upload the scan if it's needed.

I'm going to book it back in to VW, but I don't really want to play part replacement bingo with them!

I'd really appreciate any help anyone can offer.

Thanks ☺

Here's the code from the last scan,

Do you need the whole thing, or is this enough?

I'll get a new scan tomorrow.

Thanks for your help.

Is that the only error code?

16952/P0568/001384 - Ross-Tech Wiki

Yes, definitely the only code stored. I reset the codes expecting cruise to still not work, but typically it started working. I'll try again tomorrow - I have no confidence that it's fixed itself.

I guess the next port of call will be either the wiring or the steering column control module, going by the info on the link you posted.

Thanks for the help, I really appreciate it.
