Hi Thanks, I tried to remove them yesterday, the engine was cold and they were stuck in pretty well. Went to start the engine to heat it and it would not turn over, nothing. The dash now has a (red) steering wheel flashing and the temperature sigh goes between red and blue. The fuel light also flashes. I haven't looked in to the cause, but something must have lost communication and hopefully it just needs a fuse or reset. I will check the fuse under the bonnet to see if it's gone but something must be stopping the engine turning over and it looks to be electrical.
