I have an intermittant fault on my Cruise Control (fitted by factory).

I set it to 70mph on the motorway and then it will switch itself off for no apparent reason.
Often it does it when you finish indicating left after moving lanes, but has done it whilst in a straight line.
When it does switch off it often takes several attempts at pressing resume to get it to stay on again.

When it swicthes off my feet are nowhere near the clutch or brake pedals.

I also have a feeling that this all started when I had a new wheel hub fitted if that is linked to the cruise control system in any way?

Any ideas?

Thanks
