Thanks, I changed my plugs at 45k and it seemed to solve my problems. I've got about 8k on AP Stage 1

Is there a recommended mileage to change the coilpacks or a vertain mileage where they typically start to go?

What about carbon cleaning? At what mileage should we get cleaned and can any mechanic do it or should it be a BMW specialist? Can/will the dealer perform that?

Are the coilpacks or carbon covered under the CPO warranty or is that considered normal wear like brakes or the clutch?
