Tune Up

My beast has done 36,000 miles , (2002) model and has only had an oil service - is there anything to be gained by replacing plugs , air filter etc at this stage ?

you're kidding right...and i hope you mean services[PLURAL]

it's NOT a MODEL T...these cars need to have the freshest parts, it's like your tires you don't wait until ALL the thread is gone, you change them out when the depth is no longer adequate

you'll be looking at more serious repairs if you don't...especially after 50k miles...

edit:

also the car is 6yrs old i'm pretty sure the manual suggest those things be changed by now regardless of mileage

I'd wait to replace the plugs until Service II (approx. 55 K miles). Your car should have had Service I by now, which includes new air filters. If it has not had Service I yet, I'd look into it. Hopefully you have service records.

Most of us change the oil twice as frequently as the lights tell us to, or about every 7500 miles.

36k miles you say?
your plugs are functional, but way off peak efficiency...if not at end of useful life.
your MAFs are functional, but not running at peak effeciency.
your O2 sensors are probably still pretty good, but at 36K they're probably getting "lazy."
you should be changing your air intake filters yearly. more frequently if you live in a dusty/etc. environment.
fuel injector cleaning also a good idea.
a battery strength test also a good idea.

you should also be changing your cabin air filters yearly unless you like bad outdoor smells, pollen, and a musty HVAC system.

at 36k I'd also be seriously looking into changing my fuel filter. I'm sure she's cloggin up by now and stressing your fuel pump.

be advised that all of the parts needed to do the above (besides FI cleaning and battery) can be had online...well in USA anyway...for $270 and can all be DIY'd.

Erase the BMW service interval recommendations from your mind.

I change air filter every other oil change (oil at 5k-7500, air filter 10-15k). Definitely needs it. This WILL impact engine performance.
