Service and MOT..

HHmmm, I could be wrong, but I very much doubt if Citroen are going to shell out for 4 new sensors if the leak can be fixed by tightening the valve retaining collar. They're not generally in the busines of throwing money at customers unless they know there is a problem.

That's it all done, new sensors fitted and so far, the car hasn't dropped into economy mode. I asked them to look at it but forgot to check when I picked it up. They said it might be the sensor fault causing it but I couldn't see why. They might have done something else to fix it but I'm happy with the service I got.
