1990 BMW 535i (E34) M30B35 Air Flow Meter 0280203027
I pulled this from my spare parts pile, originally from a random engine with unknown miles. I've never heard it run but it did pass some electrical tests on my bench. This AFM was installed on a BMW M30B35 with a fairly early version of Bosch Motronic (1.3). If I recall correctly, it was paired with an 179 DME. I bought the car just for the wiring harness and brakes; they're currently installed in my 635CSi.
I had a spare AFM in better cosmetic shape so I didn't end up needing this part. It seems to be in great shape: the air flap moves easily, as they all should.It also passed some basic electrical resistance tests on my bench, but I don't have the equipment to properly test Bosch AFMs. The cover had been removed before the car came to me. The cover is cracked and still has some remaining sealant. I'd assume it'll need the usual bit of resistance wiper adjustment and calibration.
I'd assume it's been. Removed and re-sealed a few times, due to minor nicks & scratches.
That's not unusual for these cars, they all tend to have a. I'm told that the smaller M20 AFM electronics can be swapped into this larger AFM chassis for a cheap high-flow AFM. Calibration would be required in that case. BMW lists the following parts as being part of this assembly.
