After countless hours of searching online and messing with my e46 I finally got rid of p0171 and p0174. Problems I had were all small vacuum lines were dry rotted, valve cover gasket and disa gasket needed to be replaced, intake boots were cracked, fuel filter was clogged, and the ccv lower oil vent hose was broken. After all that and two drive cycles I got all monitors ready with no codes. I noticed it’s easier to set monitors when using cruise control than by trying to hold a steady speed with your foot.

[@billjoyce7464]

You saved us a few hundred dollars. Your point that most of the causes of these codes is loose connectors around the air intake pointed me in the right direction. Turned out to be a hose where the clamp was never tightened. Great video - thanks for sharing your knowledge!!!

Just took the plunge and investigated my lean codes - the intake boot to the throttle body/ICV was torn.
Absolute PIG to remove, thanks to the kind BMW engineer who installed the hose clips facing INTO the bulkhead.

[@epicnoise206]

This was posted JUST at the right time for me...the dreaded P0171 and P0174 (with a P0313 for good measure). Hearing the whistling on the driver side on acceleration. Figuring it's the intake boots, which will be replaced as soon as they arrive from FCP Euro. Thanks Jason!

Thanks for this and all the other helpful videos! Your E46 diy tutorials are the best and have helped me fix a salvage pos 2001 325i nightmare that someone conned my mom into buying and rebuild it into an actual decent and reliable daily driver that passes smog. It’s starting to look better and run smoother every day and we were able to pull this off on a very minimal budget. Note that I am a 5’2” tall 110 lbs female with pretty good hands but no formal training in mechanics. If I can do it, anyone who isn’t lazy and follows good instructions can as well.

[@althomas5735]

Excellent video! An automotive diagnostic smoke machine is your best tool for finding these leaks. Disconnect the boot from the MAF and send smoke through the boot. This test the entire intake system and will show any gross leaks easily, although it may not show all vacuum leaks. Also know a dirty or aftermarket air filter esp on an E83 X3 with M54 can also cause lean mixture faults. And don't forget the fuel filter. Good fuel pressure doesn't necessarily mean good flow.

[@Saldanga007]

I still didn’t figure it out my 5 series P0171 code, but your video is one of the best on this issue on TH-cam great job

[@hakeemg6433]

Are you a mind reader or something? This code just came up on my car an hour ago 😂😂😂😂. Perfect timing

[@bxtrclrk1710]

This is one of the better videos on this subject, but it too fails to mention a pretty common source of the vacuum leak. On the underside of the intake manifold, pointing to the rear, there are three nipples that are used as attachments for vacuum lines on some BMW models but not others. On many models, the nipples are covered by rubber caps. With time and heat the caps can crack and leak, or even fall off, thus creating an even bigger leak. Check these first. If this is the problem as it was on mine, it is a 5 minute $0.50 fix.

[@Orph3us33]

Can you do more 03-05 325XI videos? Your videos are by far the most useful for a TH-cam taught rookie mechanic like myself. I hit a deer in my car and can’t let this car go.. It has a ton of problems but your videos have helped me get a lot done so far. Where I am located in Montana, I have not been able to find a mechanic worth his salt out one that doesn’t use the bmw logo to his financial benefit so your videos are pretty much my only hope.. thank you for your service!

thanks to you I fixed a vacume leak at disa valve big o ring.

[@stewartcollie2459]

Excellent video. Let me add one more thing to look for on the list of potential air leaks.
I have a 2003 Z4, 2.5 engine. It would throw "system too lean" codes, both banks. I isolated the problem to times when it was idling. That usually points to vacuum leaks. After repeated inspections of every hose even remotely associated with the intake system downstream of the MAF I could never find the leak. What I did find, ultimately, is a small black plastic pipe sticking out of the rear of the intake manifold. It is clearly meant to be used as a vacuum source, but it is not used for anything in my car. It is meant to be capped, (or plugged in some fashion )but the cap had fallen off, allowing a substantial stream of air directly into the intake manifold. I capped the pipe and the codes went away. A $0.05 part after 20 hours of looking.

Very good video and it covers all normal E46 M54 vacuum leak spots.
Too much people around who look fault codes "oxygen sensor deviation limit" etc.. "hmm, must be oxygen sensor"..

[@alexb1310]

My p0171 and p0174 codes were triggered by the DISA valve flap armature (white hollow lever under the small black triangular cover) that snapped and since its hollow on the inside was letting enough vacuum by to trigger the codes. I'm shocked since the hole was only 3mm in diameter but it did trip the codes and made the idle stumble a little.

[@tki_detailing]

Booster fine, idles smooth and runs perfect. No lights on at all. Will stay at 1200rpm until I release pedal. Cheers in advance....... Tim

I have 2003 BMW Z4 with M54B25 engine. I have a problem that the car has vibration on idle. I push the brake pedal then change the gear from "p" to "D" position the car has stalling. While driving i do not feel stalling or anything. It occurs only stopped position. I replaced the spark plugs but problem is still going on. Car has 132k Kms and ignition coils were not replaced before.I wanna hear your suggestions. Thanks.

[@randyfitz8310]

9:04 I was able to replace the booster on an E46 without disconnecting any hydraulic lines from the master cylinder reducing labor by not necessitating brake system bleeding. I did a little bending of the heat shield to create space, then straightened it afterward.

[@johnsmith44573]

Didnt realize that ms45 cars had the IAT built into the MAF. Pretty interesting. Only thing to mention would be that some cars have a line running from the fuel rail down to that cap on the ccv, so if the cap is missing, it could be that the line has rotted away, or popped off.

[@Logic7repair]

Disa valve has that plastic flap which wears out, but more importantly it’s got a membrane in that vacuum valve which goes bad often creating vacuum leak even if you sealed actual monifold to disa connection. Replacing flap and membrane or entire 300$ disa valve is a must after 10yrs

Thanks for this awesome vid! I have the same issue on '15 BMW X1 and my BMW dealership performed a smoke test which they said found no leak. But they identified the following issues; 1) There is a leak in crankcase system and recommended to replace front crankshaft seal and b) found oil leaking from vacumm pump. Do you think these could be the reasons for the P0171 code? I took my car to my local guy and they said most likely these are irrelevant to the engine code and won't make the sign go away. Would highly appreciate your insights on this matter.

[@ezram8511]

Caddi Man eiter valve covers have a crack you cant see or the gaskets on the valve cover bolts are dried up

[@oISe7eNIo]

My trusted BMW werks place actually replaced the cover itself as they will warp and never seal even with the brand new and properly fitted gasket. I'd try that route, and make extra sure the gasket is not cinching up during the reinstall. Best of luck!

[@PureRocker20]

Could be the failed CCV/oil separator unit - which could result with too much positive crankcase pressure so it blews the gasket at the weakest point...
P.S. Original BMW gaskets and other rubber parts from dealer are made of much greater quality rubber.
