Other than regular servicing with genuine parts and high quality oil there is nothing you can do other than hope nothing breaks. None of the parts you mention has a servicing requirement so other than driving there is nothing to do.

Any high milage car is a risk but based on the age/mileage yours has probably lead an easy motorway life so keep your fingers crossed.

Servicing at a BMW dealer is surprisingly economically priced but repairs can be quite pricey. Servicing at our local BMW indy was only a few £'s cheaper when I enquired but he save me quite a sum when a spring broke.

doh...should have said let turbo warm up after starting, and cool down before stopping.

Thanks for the replies,

Yah I hope the DPF is OK as it sould have had good few long runs.

About changing gearbox oil, is that for the manual box too? I know a good mechanic so will ask him to do that. Havn't heard of the rear axil oil change yet.. but will enquire too.

My work is only 12 miles away which I drive to, but its start stop after the initial 8 or so miles.. So I might need to take a long drive one in a month or so and hopefully this will keep the DPF in shape.

Will also let th turbo warm up after starting, and cool down before stopping.. Had a Mini Cooper S, with a super charger, so kind of used to this.

A supercharger is driven mechanically by the engine and won't carry on spinning away at 100,000rpm after you've shut the engine off cutting its oil supply. Nor do displacement type superchargers (such as the Cooper's) run at such high RPMs.

Turbine housings can reach 400 - 500 C, but mechanical superchargers' only source of heat is the engine block itself and maybe 120 C from compressing air, so don't overheat oil anyway.
