Paul, thanks for your reply your advice is most helpful, I forgot to mention that the fault always occurs when it is in cruise control, I don’t know if this means anything.

I was going to have the actuator changed at my local garage but they say I can’t just change the actuator, I have to change the whole turbo, is this correct?
