Cheers myglaren
I thought i had seen something about it some where,I disconnected the earth on the battery on sunday to change the steering wheel on sunday, but didnt think then but all seems ok, I have to take the battery of for the clutch change soon so will remeber for that.
Thanks again

Is all that rigmarole really necessary myglaren? I've had my battery disconnected umpteen times, to fix an airbag fault, a turbo fault, etc.etc., fitted a new battery (twice) just reconnected it and never had any problems.

It is certainly recommended as shorttucs can lead to loads of problems particularly with satnav equipped models.
It is certainly a pain but less of a pain that a possible trashed ECU.

One quick thought , when would car re learn the key ? As i read i need to put the key in with the ignition on then press a button so the key talks to the car ? I must have done it wrong as i cant shut the windows with my key at the moment. ?

You might have to hold the window switches up with the window closed for a few seconds. One of my windows stopped responding to the button the other day and that made it play ball again.

you may have lost your antipinch, imperial..

you might have to open and close all windows once before autoclosing works.
