I did do searches, but didn't really see anything in the R230 sub-forum (plenty in other forum), just wanna post this for future searches.

last week, my car starts hesitating when accelerating from stop, once engine died when coming to a stop. Engine light came on, code was P0102.
ordered a new Bosch 0280217810 Mass Air Flow Sensor (MAF) off Amazon for $130. installed it, and been working fine so far !!

install took may be 5 minutes, no tools needed. pop of plastic air filter assembly on top of the engine. MAF is towards center back of the engine. disconnect 1 electrical connector by squeezing top and bottom clip. remove the round clip that circles the MAF. then MAF comes straight off. pretty simple job.

Out of curiosity, did you try spraying the MAF with some cleaner first?

I didn’t. MAF cleaner was like $10. New MAF was $130 for Bosch or $60 for off brand. I didn’t want to do it again (wasn’t sure how much labor required), just bought new.

Now i now how easy to swap it, i would use cleaner next time.

Btw. I could swear the car drive much better than before (stuttering). I started a thread a month back about having difficulties modulating throttle. Issue is gone.

Oh, I'm sure it's an improvement, the MAF is crucial for managing fuel air mixture. Which reminds me.... I should spray my MAF.
