Car went in for it's software check/update this morning. Engine ECU was up to date, Auto box wasn't so that was done.

Also he applied Field Remedy 1884, which doing a quick search appears to be with fuel phasing because of juddering?

Nice guys, Now Vauxhall Byfleet.

Got to go back later to get my new flip keys, I needed a new key and as they are flips now and they are going to charge me £35 to program them anyway, I bought two!

Car is running better now and no spanner light in over a week, after a couple of good motorway journeys with a mixture of thrash and cruise. Also with some injector treatment in there.

See how it goes now, also MPG appears to be heading in the right direction (as in up).
