Went in for what I thought was just an oil service and service guy says computer tells him car needs air filters and spark plugs as well (all covered under 3yr warranty). Didn't complain but I thought this was really odd. When I asked about it he gave me the old "All M3's require plugs every 12k miles". Ok buddy.

Anyone else come across this in their higher mileage service appointments? Any other surprises with even higher mileage?

If it's under warranty I guess no biggie, but 12K seems pretty early.

Porsche does them every 30K.

Some of bmw maintenance used to be based on oil changes. I believe at 1 point air filters were every 2nd oil change and spark plugs were every 3rd oil change. I honestly couldn’t tell you though. Did you change your oil once already or is the 12k your first oil change.

Yea if it’s your 3yrd visit it may be due just based on time.

Technically this was my third oil change including break in service. Maybe that's why. Car is a 21 but only 18mos old.

For F80, they did recommend spark plugs at 3-year or 36K interval, whichever comes first.

18 months/12K seems a bit early though.

Yeah was def. unexpected. Car said it needed them so I am curious what the metrics are that the car uses to determine wear.

Manual says no plugs or air filter until 3 years or 30k miles.

On a turbo car, I would replace spark plugs every 15K at the longest. Fresh plugs every year is what I normally do for turbo engines.
