    New switch should be here early next week , will let you know how it goes.
    PS... have been driving daily with the switch unpluged and the contacts bridged on the plug - all is as normal (without CC obviously).

    Logically it should be a bit underfuelled this way

    You are 100% right, down on power a little, but if you take it easy you dont really notice it. Just a short trip to work on the few days i go! We will see the difference next week!
    That is if the clutch switch ever turns up, cheap prices in the UK, but don't be in a hurry for delivery (well not with this supplier anyway - no names mentioned)!

    As promised, Update on the new Clutch Switch.
    Fitted it last evening and went for a drive today - all symptoms of over run on gear change gone, and Cruise works fine. Obviously a faulty switch, but still cannot understand how the old one would disconnect cruise control, but not defuel the engine for gearchanges?
    Thanks for all your help guys, particularly Sierrafery!

    I'm glad it's fixed, as about the oddity with the CC i think the old swicth closed but with a certain resistance due to the oil ingress and as you said in a previous post: "voltage may be enough to disconnect cruise, but not enough to cut fuel" with the correction that it's not about voltage but about voltage drop as the switch closes to earth so the only explanation i can find is that to disengage CC for the ECU is enough a voltage drop on that circuit while to cut fuel it needs solid earth .... never mind, important is that it's working now
