The temp resistance of the old AFM worked improperly so I replaced with an used one.
The AFM in my car (I own the car for 20 years) with parts# 0280203027, and the used one # 0280203029. My car runs normal after replacement.
The myst is 0280203027 supposed using in BMW... but it has been in my car for 2 decades (I didn't know if the previous owner replaced it?)
Their appearance looks same. Only difference in temp sensor (see photos -- 0280203027 with copper wires ; 0280203029 with a rubber covered)
I saw a factory selling brandnew #0280203027. Is it a good try to replace the used (but runs good) 0280203029 with a brandnew #0280203027 ??
