Not sure to tell you the truth - the car has been back to our local Ford dealer and so they might have done it without mentioning it to us. But otherwise not as far as I am aware
Thanks - will try this. Would it also be consistent with the fault being worse when the air conditioning is on - or the lights and windscreen wipers together?
We have just had the car back from the garage. They didn't find a leak - nor could they identify any further faults. Do have any other ideas? Thanks.
I am afraid we asked about the fuel injector and were told this had been tested and was OK.
