Cruise control not working: Any help please

[Ricke53]

Thanks for the add.

1st post, noob on here, but really need help with this one!

My ‘02 X5 3.0d manual has lost cruise operation.
It lights up the dash symbol but fails to work.
I’m going on my longest car ever journey on Friday and I’m getting desperate!

I’ve replaced slip ring and button set on steering wheel.
I have access to diagnostic gear: Bosch KTS and snap on solus.

Prior to noticing the cruise not working I had an issue with the dsc module codes 30 and 33 wheel speed circuit intermittent and ended up sending module off for repair, since then a yaw sensor circuit was intermittent - replaced sensor 3 days ago -ok so far.

Continual reoccurring EBV fault / fault 189 in kombi instrument module.

Not a clue how the cruise goes about it’s business (through what modules) and could do with some advice

I’m well aware how the cruise operates- I’ve owned this for 10 years now.
