Jobs done were:-
1. Sunroof reset. It wasn't closing properly.
2. Rear passenger door latch replaced, due to malfunctioning locking mechanism.
2. One corroded tyre valve replaced.
4. They also reset the computer at my request, to remove the "open all the windows when you unlock the car" feature.
The car came back cleaned inside and out. No charge
So full marks to Derek at Lexus for organising this. Great service, thanks.
