I went to see Din, my mechanic at USJ, and asked him to change the AFM. Upon checking, he informed me that the price of a brand new AFM was $1,500 <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> (couldn't remember exactly though). What he offered me was to open up the AFM which was not a standard practice by default, normally got to ganti the whole thing if rosak - I agreed, and then he cleaned up and straightened-up the mechanical "flapper" or "valve" (dunno what was it called) inside that 10-years-old still original Made in France AFM. Lo and behold, when I got my car back, the performance felt better. Even the fuel consumption improved again. Last year, my baby developed the same symptoms again. I thot it must be the AFM again and sent her to Din. He opened up the AFM housing unit again, confirmed the mechanical components still performed like how they should. He then open up the ECU and did something I did not know what for 2-days and finally, when my baby was returned, it behaved like UDM again. The machine is now 13-years-old. I really like the car and the thing I am not yet satisfied is that I don't feel like her performance is as tip-top as 10 years ago.As for the E46, I changed to the K&N replacement unit two months ago. Instruction said oil the thing after 40,000km.. I only drove about 2,000km since then. What scare me now is that Bro 330Ci said he threw away his K&N unit after damaging his Air Mass Sensor!</blockquote>
