Hi everyone. My car requires to replace a MAF sensor. The OEM number of the original MAF I removed from my car is 0000940148. But I cannot find any new MAF with this OEM number. Also, I find there are lots of MAF which OEM number is 0000940748. And it seems to fit my car? As I check the vehicle fitment, 500SE with M119.970 engine is on the fitment list. The only difference I find is 0000940148 is 5 pin but 0000940748 is 4pin. Anyone here has used 0000940748 while the original one is 0000940148? Many thanks.
