2882 & 2883 codes

hello - I have a 2006 X3, M54, 83k miles. Chasing down a lean code last year, less than 5k miles, I changed the fuel filter and fuel pump, as well as new plugs and coil packs (bosch). The pump and filter fixed my problem and it still runs great, but now I'm getting Service Engine Soon light with codes 2882 and 2883 - mixture prep. It also seems to be dropping fuel pressure, as on cold start it cranks a lot before firing -= can turn to acc couple times anad fires right up. I do not have needed equip to test pressure at shradder. What's thoughts? New starter also

Do you have installed the k&n filters?

Think you may find this of interest...

Could be many things, including leaking injector(s). Do a smoke test to check for vacuum leaks. I read that a cracked intake boot is one common source on the M54.

I have standard Mann air filter, and I've cleaned the MAF, and inspected the intake boot, which appears fine. I'm getting a code for both bank 1 and 2, so I don't think I would have multiple injectors fail at the same time. I really need to do a fuel pressure test, but I don't think I have the right equipment. Could the leak detection pump cause this issue? The can hear the pump or something after I turn off the ignition, quite regularly.

Fortunately, fuel pressure tester kits are readily available, even cheapos from HFT. Be safe!

That's likely the gas-fume pump, if the sound is coming from the right/rear on shut-down.

Smoke test it.

I will try to do a smoke test this week - never done one before, but I have read some on the process.

My experiences have been to research the issue through various avenues/sources, best to do your due diligence...
I'll offer you this....

OK, so I'm still tracking this issue -- codes 2883 & 2882, both banks running lean. Car runs fine after starting -- cranks a LOT before firing up, and can be somewhat alleviated if turn key on couple of times and let fuel pressure build. Within 3000 miles, a new fuel pump and filter replaced with BMW brand; new plugs and coil packs (all looked good on old). 83k miles on 2006 3.0 - regular oil changes; and recent change of all other fluids except brake. Although I've not done a smoke test, I have examined and looks fine. I read a link that Duke posted on fuel trims, so I hooked my scanner up and took some values on a test drive after engine had completely warmed up. Short-Term was .53 on bank 1, and .64 on bank 2 during cruising speed and no load; neither value changed if I got on the gas hard. The Long-term values were 2.66 for bank 1 and 3.19 for bank 2, and cruising, and jumped to 7.48 (bank 1) and 8.05 (bank 2) if I got on it hard. From what I read, these values seem to be fine, and contradict notion of vacuum leak. I next went to HF and got me a fuel pressure gauge kit. I hooked up to the shraader valve up front, and started engine, revved engine, and pressure stayed at around 48, jump a bit with revving. Turn the car off, and pressure dropped to 40 within an hour, and 10 within 24. What next? Revisit the fuel filter with the built in regulator, or do the check for weeping injectors?

I had a vacuum leak at the small disa inside the intake manifold. The o-ring was leaking. I agree with Duke. You need to do smoke test. I think I spent like 20 bucks to make that smoke machine.

Your fuel pressure is low, should be above 60 (or even 70s) psi IIRC. Mis-installation of the fuel pump/regulator on these is quite common, FYI. Run a smoke test becase thats easiser than getting into the fuel pump, but don't discount it.

I'd perform the injector bleed down test.

I cleared the code after the fuel pressure test, and took her to Tail of the Dragon -- drove like a champ! Took 400 miles before the check engine light came back on -- soon after a start up of the engine. I've got a spare fuel filter, gonna change it and see if it's the regulator.

I had those codes on my 04. I hookedup NT 510 and looked at live data. at idle STFT normal, LTFT about 9. at 2500rpm LTFT approach 0. this result indicated vacuum leak. no visible leak detected with smoke test. replaced disa valve oring, codes remained present
replaced disa, intake boot. 2882 and 2883 code cleared

My LTFT increase with higher RPMS, while STFT remain steady across RPMs. From what I've read, that does not indicate a vacuum leak. Coupled with the losing fuel pressure, I think I have an issue in the tank. Does EvilSideofGood have a link to make the smoke test apparatus? Thanks

Look for "paint can smoke tester" on Youtube and eBay. Crude, but works. Be safe!

I got this problem solved - it was the regulator built into the fuel filter. The problem filter was only a few months and few thousand miles old, but wouldn't hold pressure. Starts right up now even after sitting for 24 hours. BTW: Here's a tip for you guys. If you want to get the smell of gas off your hands and forearms, wash as normal, then coat affected body parts with toothpaste and lather that up good, rinse, and wash again with regular soap, or not. I do the second wash to rid of the mint sting that comes from minty toothpaste.

Possibly so... an aftermarket fuel filter?
