On my XF. Turned off the auto wipe for wipers and auto head lamps off..Windscreen covered in frost so don't want them working over an icy screen when 1st starting! The auto head lamps I turn off because the 1st thing you do after the windscreen has defrosted is to give a squirt of washer and if the head lamps are on and fitted with washers the pop out washer in the bumper can be frozen to the bumper and ends up with the motor pushing and snapping the cover off.
Hi, nice car, hope you get it all fixed up, if you need any help just let us know, here are some wheel centres :

That's about right for a 3.0 petrol, maybe a bit more on a run.
My diesel is averaging around 38mpg in general tooling around and up around 48/50+ on a run.
Worst I've seen was 22mpg but I was racing something at the time!!
I always use mytyres.com find them extremely competitive and you choose the fitting centre and date/time of appointment for the free fitting of your choice. They use National tyres and they do not charge any extra for tyre disposal and balancing or valves.
