My 21 M2C is at 27k and I'm curious, what do I need to handle for the 30k service? Regular oil changes at 5k and plugs done at like 4k ago(my choice their dime). Brakes still meaty, fresh ps4s and will have a replacement splitter done at the time. What else should I look out for? Thanks guys.

You should be due for a (free) brake fluid replacement, and maybe air filters.

Ahh yes, I did the filters also. K&Ns a few k ago, at best. Ya I was thinking about having the brake fluid and maybe diff fluid flushed. Is it too early for a carbon cleaning, is that even still a thing with direct injection?

Waaaay too early for cleaning carbon deposits off the intake valves. These engines don’t have a demonstrated problem with deposits — especially not at 30K miles.

Some other things to attend to:

• Brake/Clutch Fluid Flush (every 2 years)
• Engine Air Filter (every 30K miles)
• Manual Transmission Fluid (every 30K miles or 4 years) (probably a bit aggressive)
• Rear Differential Fluid (every 30K miles or 4 years) (possibly a bit aggressive, depending on your driving environment/style)
• Accessory Drive Belts (Serpentine Belts) (every 3–4 years or 50K miles)

If brake fluid is every 2 years wouldn’t this be an off year?

First scheduled change is 3 years, then every 2 years afterwards.
