Think I'll just bit the bullet and get a new imrc box best case it fixes the car, worst case I sell it and loose 50 quid!

If the new imrc doesn't solve the issue I think I have no choice left but to give it into Ford for a look; which I imagine wont be a cheap experience

Fuel is always above the quarter - not a believer on letting it below that unless absolutely necessary.

Only warning light is the battery on occasionally and the engine management but that's due to the lambda sensor fault which has been there for a year or so. Have tried to fix it but that's a separate issue for now!
