I completed my first service last weekend and now my trip mileage has jumped up dramatically. Has anyone else noticed this? I wondered if they've done something to the ECU?

That's great news. What kind of mileage were you getting before the service and what are you seeing now?

Make that two of us - can you provide a good idea of what it was pre/post update?

Also just had the software upgrade when the car went in for a warranty issue. No service done yet (only 10,000 miles) but improvement of 3 or 4 mpg for similar journeys but noticable. Only been a week and 30 miles so will keep watching and posting.

What did you do to get the software update? Was it as simple as asking the dealership for the software update or did you have to specify a problem that the software update resolved?

The dealership knew there was an upgrade and also a note that the earth connection needed re doing. It happened that my car was in for a couple of warranty issues (bulb gone in rear brake light and squeaky window winder).
