Hi Trevor
Thanks for taking the time to reply - much appreciated. Quite strange really as we were doing rather a long road trip over the weekend (down to your way actually) and the mileage screen illuminated, flickered for a bit and then stayed on. It comes and goes intermittently so I'm assuming either a dry circuit joint or loose connection to the cluster. Was a bit of a trip really since on doing it the developed a heating issue (hot in the side vents, cold set on the air con) and the oil level 'min level' sensor seems to be playing up, not to mention both front wheel bearings giving up so plenty to be getting on with and resolving it seems !
Cheers
Lee
