Thanks for that and I have read the manual and put the code in a number of times but still no joy, hence asking you guys, cheers.

What do you mean by - Rtfm?

Can anyone help? I was advised to disconnect my battery to try and get rid of a Sat-Nav fault (another thread!). Re-connected the battery - alarm etc going off - message on dash 'engine immobilised - press remote or key code'. I did the driver's door lock 4 to left, then key code turning key...

I have a 4.6 Vogue on LPG and get an average of 13mpg. No effect on performance.
