I have had the same intermittent fault with the cruise control. It went into the dealer yesterday to have it fixed. This is what was written on the report from them -
"Checked operation of cruise control buttons on IDS and all working at present. Various fault codes for cruise control present but none current. Carried out ETIS checks and ascertain a known concern relating to corrosion with the airbag clock spring electrical contacts. Remove the airbag to gain access to connections. No corrosion present but the connection to the clockspring WAS loose. SLIGHT damage evident to connector but should not harm operation. Clean contact & lubricate & re-fit. Road test and all working correctly"
This cost me £90.94 to have put right.
I am concerned that they wrote "known concern relating to corrosion with airbag clock spring electrical contacts".
If there is a known concern, and it is affecting the function of other things - like the cruise control - they should be sorting this out, not waiting for customers to come in and pay to have it fixed. Surely this is a safety issue to re the airbags.
At least your dealer justified and explained clearly what they were charging for. This was probably the issue with mine. I was charged £84 for their "diagnosis" that they "suspected" the switch was faulty. I will never know, as I recovered the £84 from the credit card company and got rid of the car due to their apalling service.
