Specific notes: For 325e, 528e M20 cars. Bavarian Restoration refurbishes all Bosch Air Flow Meters to meet factory specifications. This is one of the most important sensors for your engine. After 20 or so years, these units really start to send your ECM poor and inaccurate feedback. The AFM has two sensors in one unit.

An Air Inlet Temperature sensor, which provides feedback to the ECM for incoming air temperature. A potentiometer which provides the ECM feedback voltage that is linear with respect to the opening of the internal flap. Non-linear for older sensors and ETA BMW's. After many years of use, the inaccurate feedback will affect economy, poor running, poor idle, symptoms of misfire, and loss of power.

Bavarian Restoration Refurbishes Air Flow Meters using the following process. Heat tank soak, ultra sonic cleaned, bead blasted, and clear coated using high temp ceramic paint. Test intake air temperature sensor resistance over the heat range specified by Bosch. Test AFM door spring tension and adjust accordingly to known Bosch specs.

Disassemble wiper arm and connector assembly. Clean incoming, and outgoing contacts and bend them to contact fresh material. Clean wiper arm contacts and primary grounding post.

Adjust wiper arm to contact fresh material. We will add aux grounding to earlier units. Reassemble wiper arm and connector. All contacts touch fresh new material only! All mechanical pivot points are lubricated with liquid Teflon. Measure voltage signal output with oscilloscope and adjust if necessary. We run a variety of tests including quality repeatability, linearity testing (or non linear for eta AFM's,) quality repeatability in the idle genre and the fully open genre. Every AFM is thoroughly tested over a variety of conditions. AFM is finished with high temp ceramic clear coat paint.

Lid is sealed with silicone to ensure a moisture and water proof AFM. Every customer receives oscilloscope print-outs of their individual AFM being tested.

Bavarian Restoration's AFM's are better than the competition because.. Unlike our competition, we personally test each AFM on our test bench. Every aspect of our AFM's is thoroughly tested and proof of testing is provided to our customers for each individual AFM we refurbish!

Please note the AFM's in our pictures will not represent the actual AFM you receive. Our AFM finish is very professional and exceeds OEM finishes.
