Approximate service intervals in Europe for the F30

Oil - Every 30,000km ( 15,000miles USA) or 24 Months (USA usually does 12 months)

Microfilter - Each oil change

Engine Air Filter - every 2nd oil change

Spark plugs
- N20 328i Every oil Change ( EDIT: see below)
- N55 335i Every 2nd oil Change

Diesel engien fuel filter - every 2nd oil Change

EDIT: Asof March 2012 production NGK has upgraded their sparkplug design so N20 with teh new plugs will only need replacement plugs every 2nd oil change.

Bump For the extra interest now that cars are arriving

Thank you Sir ...but i guess for US, there is no need to worry about all this since BMW will take care of the routine maintenance during the first four years...

Yes and here BMW does for 5 years or 100,000km (62,000 miles)

But many want to know or look after the car themselves

Do the spark plugs have to be changed that often?
My current car has 130000km on it and has never needed new spark plugs...
Or is this a BMW-thing?

Do you drive a petrol or a diesel Astra ? If the latter it only has glow plugs to start the engine up. It doesn't have sparkplugs like a petrol engine.

My bad
Should stop asking silly questions. But I've learned something, that's important

Daarom dan de bijnaam 'zelfontbrander'?

But is it normal for a petrol engine, that they need to be replaced so often?

A Normally asperatred petrol usually makes it to around 80-100,000km before needing plugs

The new turbo engines are requiring a much more frequent change

[Red Bread]

Are you sure those are correct? Spark plugs at every oil change for the N20? Any mention of coil service life? Certainly adds a good bit of expense to out of warranty service costs if true.

[epiphone3]

My E90 has spark plug change interval set at 160,000 km. The interval on the N20 seems shockingly frequent.

If that is the case that spark plugs need to be chagned that frequently, it leads me to start thinking about if these turbo motors save the end user any money at all. Think about it... change spark plugs very often, possibly five times more often in the case of the N20 and then on top of that you have to get the intake valves cleaned every so often to maintain the performance/economy of the engine due to the Direct Injection. All this to save like 10% on fuel.

Yes, spark plugs at every scheduled oil change for the N20
USA and Europe

[Red Bread]

Wow. So along with the current $150 oil change, you get to pay for $10/plug and labor, plus a mircofilter. I suppose a non-warranty oil service will now be $300 or more. Still unclear on how frequently you need to replace the $46/coil on top of that.

[Redcapote]

Okay, this thread just shocked the sh*t out of me. Glad I learned this before I up and bought one. Then again, I don't have a woman or children to spend on but... yikes.

[CE750Jockey]

New plugs every 15,000 miles w/oil change?! That's ridiculous and unacceptable. C'mon, BMW.

There is no replacement schedule for the coils.

[longtran@ltbmw]

That is some crazy maintenance schedule.

I'm glad I convinced my mother to get an X3 28i with the inline-6 rather than waiting for this craziness... there's lots of trade-offs invovled with this new 4-banger.

The N55 isn't better by any means, 6 plugs on every other oil change, meaning on avg 3 plugs per oil change.

Which using simple math would say it's 25% better.
Of course our N54 is at 41k miles and has already had plugs and coils replaced.

Yeah, but the X3 28i my mother bought uses 6 plugs for 160,000 km. That's much better.

You cannot compare a non-turbo engine with a turbo engine.

How does BMW's service interval compare to its Audi and M-B counterpart? That's open for anyone who knows the service intervals for today's A4 or C-class.
