I service it every 6 months regardless of miles, and rotate the wheels (and spare) every 1000m, to keep even wear for the 4x4
similar as I do a service every year regardless of mileage , even in a year if it’s below 1,000 miles I’ll still do a full service
ref ur LP pump I took the complete assembly out with the filter and changed the lot , took it al, apart cleaned everything up before reinstalling a new pump and filter , plus cleaned the connector and associated wiring up as it didn’t look very good, ie, some of the wires had gone green so cut them back , redone with shrink tubing on there to protect it form the weather
talking of servicing I desperately wish to drain and refill my ATF oil , don’t like power flushing gearboxes , got 10 x litres of the ATF, it just a case of trying to get the filler plug out and refilling it
did do all the ATF oil on the TD4 , made the world of difference as sometimes it would thud into gear from park to drive , ,plus gear changes weren’t always smooth, after the oil change it sorted out all the issues
then fitted the crankcase BMW mod and new silicone intercooler hoses , blanked off the EGR , cleaned the Map sensor at the same time , really helped the engine and gearbox run a lot smoother
am the same ref engine oil, mine uses 7 x litres and think last time I paid around £75 for millers 5/30 as wanted to get decent oil, along with a genuine oil filter
just really struggle with anything underneath the D3 or getting the wheels off , next year the rear lower wishbones will need doing but after doing the brakes really want to get the ATF oil change and engine oil/ filter done
plus 1 to never having too many tools , some of the markets are brilliant when there’s a tool stall , got a great set of dentist like picks which were perfect getting O rings off or for cleaning threads etc off
sorry I’m waffling , lol
