'04 330ci - Best place to buy Mass Air Sensor

Is the current thinking still to go with OEM?

Been scouring the Internet for a deal. Anyone find one recently?

Thanks.

Are you sure yours is bad? Very often you'll get a MAF code when it's just a common air leak, of which we have many. Lower intake boot and any number of vac lines crack. Just saying. For older models, I believe there was a hyundai MAF that was identical...don't think that fits yours, but I don't know for sure.

But honestly, I would just buy a used one that's been tested, and give it a good spray cleaning.
I have about 3 spare MAFs for my car sitting in the basement that I scavenged from junkyards. (they don't work in your car unfortunately)

I've replaced, literally, everything but the MAF sensor. I've got another older thread on that process which I don't care to resurrect at this point.

Last full crankcase indy BMW shop crankcase smoke test revealed zero leaks after two prior tests which revealed a couple very minor leaks which I couldn't see with my DIY test. Indy guy believes, after spending about six hours on the car and speaking with code reader rep, that the problem is very likely the MAF sensor, but he cannot absolutely guarantee it. There's nothing else to try at this point.

Thanks. OEM Bimmer Parts is what I've been thinking. Best price I've found to date.

I have used this number 2816437100, got my last one from FOURGREEN AUTO PARTS, my part is the same as the Hyundai. That one lasted two years, and was like $160 or something.

I just ordered another, for $44 via amazon. Bet this will last two weeks! We'll see.

This doesn't apply to 330's made after 2003.

Actually, it never applied to 330's at all. Those always had a bigger MAF.

Replacing the MAF will do nothing to resolve high Fuel Trims at idle or cold start problems.

If you're positive you need a new MAF, the advice to salvage one from a junkyard or even borrow someone else's is probably the most cost effective approach. You mentioned scouring the internet and if you're looking to buy new, this might save you some time:

Siemens/VDO (13627566983):
AutohausAZ: $307.38
Bavarian Autosport: $309.95
Bimmerparts: $372.61
Bimmerzone: $334.95
Blunt Tech: $359.42
BMA Parts: $266.08
ECS Tuning: $324.15
eEuroparts: $320.99
FCP Euro: $314.95
Guten Parts: $384.09
OEM Bimmerparts: $294.00
Pelican Parts: $355.25
RM European: $357.97

NOTE: Currently, BMA Parts is even cheaper with coupon code SPECE30 ($252.78).

Genuine BMW (13627566983):

^^^Excellent advice.^^^

MAFs are insanely overpriced and rarely go bad. A used one will do just fine. Most likely your MAF is okay and you have a vacuum leak.

Just spoke with Potomac German Auto. They have a used sensor for $75, but when I asked if there is any way to confirm whether or not it actually works before I buy and install it, the sales rep said there isn't. He then very candidly cautioned me against buying a used one, indicating that they go bad very often, so buying a used one would be a hit-or-miss situation. On the other hand, he also stated a used one could last another 100K miles. The used one comes with a 6-month warranty under which either a replacement or a refund would be provided. I'm feeling inclined to take my chances with a used one. Any final words of wisdom?

Thanks.

Gambling with a used MAF is a waste of money.

That's a good price and a good warranty. But test it on a different car that has a known good MAF for comparison. Hell, test yours on the other car before buying the new MAF!

I got my OEM from Amazon, was the best price. Having said that, it didnt fix the problem so there was nothing wrong with the old one. I still have it if you're interested!

If his MAF was $129 new like it was for 323/325/328's then yes. 330 MAFs cost significantly more when new.

Used one has warranty. No risk except downtime if its broken he needs a replacement, which isn't really a risk since you can drive perfectly fine with the MAF disconnected.

Disconnected existing MAF sensor and found no discernible difference in performance. Could this mean the sensor isn't working and the engine is running in fail-safe mode?
