I need to replace the mass air flow sensor on my 1974 1.8 914. I ordered a rebuilt Bosch one; however, it does not fit. It looks identical to the one on the car, except it is 7 prong power line plug instead of 6. My wire harness for power does not fit. The company I ordered the mass air flow sensor insists that the one they sent me is the correct one, number 0280 200 001. Just match the numbers right? Well the Mass Air Flow sensor on my car has had the last part of the numbers scratched off or damaged. I cant read them. Partial numbers read 0280 ... .... and underneath is another set of numbers that read 473 906 ... The company I ordered from was BWD.

Any suggests, guidance/help is much appreciated.
Thanks Mike

Check out the last post in this thread.

Says 74 = 6 pin, 75 = 7 pin.

Thank you! I just got off the phone with BWD and they have no 6 pin Mass Air Flow Meters in stock. Does anyone know of any other companies that sell rebuilt M.A.F.M?

I have a used AFM. Have to check if is 6 or 7 pin.

Who is "BWD"?

The Cap'n

Probably a reseller because pretty much all the remanufacture of Air Flow Meters was being done by a company in Orange that was sold and is in the Bay Area now. I forget the name but it isn't BWD.

Two numbers come up:

022 906 301 = Bosch 0 280 200 001 or 0 280 200 002 - 09/73 - 07/75 VW Porsche 914 1.8L up to engine number EC 0037551.

473 906 301 = Bosch 0 280 201 002 - 11/73 -07/75 VW Porsche 914 1.8L after engine number EC 0037552

Note the bolded numbers in the Bosch Part Numbers .. that has to be the difference in the connector pins.
