Faulty mass air flow sensor problems bmw e46

Do you have any friends with a MAF you can borrow? Take vehicle for a test drive and then recheck your intake air duct connections. Loosen the air flow meter clamp (green arrow then disconnect the duct from the air flow meter and remove the air filter housing from your engine compartment. I hope by posting my problem and hopefully solution it will help fellow members who are having similar problems with their cars. And I think it was about 600 last time (400 for parts, 200 for diagnostics/labor). And more recently i have been able to smell petrol from the exhaust. I also found out that cleaning the air flow sensor with electrical cleaner can sort it out without having to replace it, and this is what i have just done with mine, and it would appear to have sorted the issue! Install the air filter housing into vehicle in reverse order of removal.

If the o-ring gives you a hard time going in, apply a small amount of dish soap to the o-ring, it will slide right in and the soap will not damage your o-ring.

Hi all, i am new to bimmerfest and decided to join as it has provided me with some good tips for problems i have been having with my 2003 318i, so thanks for that first of all!

I disconnected the MAF, drove the car, and no more misfire faults. An unmeasured air leak downstream of the E46 mass air flow sensor will set codes similar to a faulty mass air flow sensor. And I think it was about 600 last time (400 for parts, 200 for diagnostics/labor). Yesterday, I had the SAME exact symptoms again (car would start but would die - no idle - unless I kept on the throttle). Install the air filter housing into vehicle in reverse order of removal.

It could be your MAF, but I would try to swap in a "known good part" before buying a new one. I'm freaking out that I will forever be worried about starting my car as I keep patching the real problem with a bandaid that's not doing anything?

Large Image Extra-Large Image Figure 3 Place the air filter housing on a workbench and disconnect the mass air flow sensor retaining tabs on both sides of the sensor by pulling them off. Has anyone else had this problem or seen this happen before? I certainly feel like i shouldn't have to fork that over again. When replacing, inspect the rubber intake air ducts for cracks or dry rot. Like a bad harness or sensor cable? Install the new mass air flow sensor into the air filter housing.
