    codes p01349, p0151, p0153, p0444 and wont start

    Hello,
    This issues seems to be listed in a few places but nothing seems to be directly answering my issue - so I am posting here:

    I have a 02 330ci with about 180k - the car has always run great and recently began having an issue.
    Several months ago the car would run rough upon start up but after warming up would be fine, this issue though progressed to sporadically running rough but cleared up after a shut down/restart. I changed the fuel filter and for a short time the issue was gone. The fuel pump was replaced 70k ago.

    Presently the car has progressed from starting and will run with the gas held to now starts idles for maybe 2 seconds and shuts down.

    I located a ripped after MAS hose and changed it but issue remains. The codes p01349, p0151, p0153, p0444 are showing but I find it hard to believe I have 3 coils/plugs out at the same time in a row.

    Prior to this issue the car ran perfect and MPG remained the same - interesting note, when this was beginning the miles to oil change timer reset itself back to 15k, not sure if related.

    Thoughts?

    Disregard the last code-purge valve-for now. It looks like the pre-catalyst O2 sensor for cylinders 4-6 (bank 2) is the culprit. Have the Pre-cat O2 sensors ever been replaced? They’re good for about 100k miles, so if they were changed at 100k miles they’re getting close to retirement time. Buy ONLY Bosch O2 sensors. And, make sure you put copper-based anti-seize compound on the threads.
    Also, has the fuel pump ever been replaced? They’re good for about 5000 hours of operation. Buy ONLY a Siemens/VDO pump. Try bmaparts for the best price. That way you won’t be changing the pump again in 6 months. The fuel filter needs to be changed at the same time. Buy a fuel filter made ONLY by either Mahle or Keyser. Both provided filters to BMW.

    You need to see what the fuel pressure is. It needs to be at least 50psi at all engine speeds. Part #2 in the link is the cap for the test valve on the fuel rail.

    Thank you for your message. The O2 sensors have actually never been replace as far as I know, the fuel pump has around 70k on it and the fuel filter 10 miles.

    Update, I unplugged the Mass Airflow sensor and the car runs great now although now showing a MAF code.
    Is there anything that is indicative of the O2 being the issue other than the entire bank going out?

    You most likely have a very large intake /crankcase vent system leak. Get a smoke test with a professional smoke machine at a good Euro specialist shop. If you prove, via this smoke test, that you do not have a large leak, your MAF is bad.

    Fixed:
    Thank you all for the information/assistance.
    I performed the smoke test and discovered a small vacuum leak although repair didn't fix the issue, I elected based on this to change the MAF - this corrected the issue only leaving the P0444 code. Car is running great once again.

    So now, all you have to do is change the purge valve (by the intake manifold http://www.realoem.com/bmw/enUS/show...diagId=13_0798) and you should be good to go.

    Well, unfortunately I discovered another issue - trans limp mode and battery charge light came on this week......I am going to post this in another thread. If your wondering, the battery is 100% and holds a load and the alt is charging at the moment 14.5/16 volts

    HOLD ON BUDDY !!!!

    16 VOLTS ???? OH, hell no ! 16 volts will kill your car's computers ! (Well, okay, 16 volts will only really piss them off: but this indicates that your alternator has NO voltage control, so 18 volts is instantaneously possible....and 18 volts will turn a computer into smoke.)

    Alternator voltage needs to be between 13.5 and 14.5 volts.

    As I said in your other thread, you need to be able to talk to all your car's computers. Your screen name is "newpctech". If you're a computer guy, Abel (328Power04) can set you up right away with access to an excellent diag system that you can put on your laptop. Otherwise, consider buying a Foxwell / ECS Tuning scan tool, for a couple hundred bucks.

    To add to what Chris (bmwdirtracer) has said, DO NOT START THE CAR! I’m betting the voltage regulator is toast. And I bet it’s sending out some alternating current electricity in addition to the direct current electricity. Why? The diode pack has failed. Alternating current will destroy electronics. I know-I spent 25 years in the Navy’s advanced electronics program.
    Remove the air filter box and the upper hose. Use a flashlight and a mirror to read the label on the back of the alternator. I’m betting the alternator is a 120amp Bosch alternator, but check anyway. A new Bosch voltage regulator will cost less that $60. Or, you could buy a rebuilt alternator that was rebuilt by Bosch. It MUST come in a black box.
