hey, currently have a 1985 318i with a faulty (actually, wrong meter all together...) airflow meter.

it is my understanding that this meter is whats causing my bmw to have trouble starting, firing on all cyl, and also whats flooding the engine constantly.

i have sufficient spark at the plugs and the injectors are just pouring fuel into the chambers. what im assuming is, the airflow sensor is giving an improper reading. probably because its the wrong one. (currently have part #0280202082 and i need part #0280202039)

so. what im looking for is a good deal on an airflow meter with the part # 0280202039. if theres anyone out there who has one for sale or mayhaps even a late christmas present (haha!), let me know!

in fact, i may even be wrong about what meter i actually need. im just going with how the prongs on the harness look. (#0280202039 has 5 prongs, and #0280202082 has only 4.) the chilton's manual shows the meter to have 5.

any insight is greatly appreciated
:help

in the AFM for your year and model... it is indeed a 5 prong plug at the harness.

However the AFM ( bosch 280 xxx 082 or 280 202 039) itself will have only 4 prongs - the 5th one(rightmost) cut short.

Then consider also... of the 4 prongs u see on the AFM, the 3rd prong is not used.

You are on the right track - the 280 202 039 is specific to the 318i engine. no other afm will work correctly

so it is entirely possible that this incorrect AFM is whats causing my BMW to run poorly and consume an abnormally large amount of fuel?
this seems almost too good to be true! just one part? :eek:hnoes

Have alook at RealOEM.com Online BMW Parts Catalog to help with the identification of the correct parts, and then visit Buy Car Parts - Aftermarket Auto Parts - Volvo Parts, VW Parts, Audi Parts, BMW Parts, Mercedes Parts, Porsche Parts to buy the parts. Quote the promotional code bimmerwerkz at the checkout for a 10% discount. FCG also have a lifetime warranty policy on their parts, so thats another reason to look at them.
Thanks for the help guys! however.. do u know any other good sites similar to these? im having trouble finding part #280 202 039 on either one... :conf

did you do a visual search on the part rather than using the part number that you have. The Realoem site is pretty comprhensive in what it cover.

AFM, is a possibility. The one you currently have on is for a 325(6 cylinder, i believe). Dirty air filter, another.

Q though... when was your last tune-up? If done recently, what was the plug condition(type of plug, appearance, color of burn...) ?

Make sure your plugs are of factory specs. E30 btw, does not like platinum or iridium plugs. Use standard copper core only.

THen, 02 sensors which tells ur DME brain how much time in milliseconds the fuel injection pulse should be. If u have over 100,000 in mileage, and u hvnt changed sensors-that could be another factor.

:cheers

if you are on a budget, try:

BMW Parts used and rebuilt bmw auto parts

However, If your problem is hard start and flooding, it suggest you train your sights on the Thermo Time Switch and the ECT Sensor. These 2 sensors control how much of gas the injectors should be putting out depending on engine temps.

Try autohausaz.com theyre out of arizona but soooooooooo much cheaper than anybody around here. Theyve saved me thousands on my '90 735il and they have a mass airflow meter for mine so they prob will have one for yours.
