Quick update:

After thinking I had fixed my car by cleaning the connector that goes to the actuator the problem had returned

After having a independent chap have a look at it, it turned out to be the OXYGEN SENSOR in the exhaust!

dont know why evans halshaw at goole didnt find the problem after hooking up their laptop??? and taking my 60 quid and leaving me none the wiser, but telling me they need to rebook the car for further investigation ££££, and then telling me the flywheel was knackered?? ( clearly just out to make as much money as they can )

After looking at all the different forums to self diagnose the problem myself... this is the one thing that none of the forums have said to check...

SO CHECK THE OXEGEN SENSOR TOO! my problem solved
