Hi all. I have an annoying intermittent problem with my R75 cruise control system where it either fails to engage or disengages whilst driving. The unit has been opened and checked out and all is clean, no corrosion, and no fault codes are registered on the ECU,via a TestBook diagnosis. Normally when failing to engage at all, if you pull over and switch off engine for a minute, then set off again, it all works fine for many miles. Any ideas ?? Really starting to p me off now. Its a 75 Saloon, Conno SE Petrol 2.5 Auto, Dec 2004.
