Check Engine light

My check engine light came on today, the code was P0171. The worker at autozone said that it could either be the o2 sensor cause it did read bank 1. He said it could be the o2 sensor bad or the catalytic converter clogged and sending stuff back and what not. Also wondering if it is my catalytic converter could it at times send little white smoke through my engine compartments at times????

Cats will last the lifetime of the car most of the time. I doubt they have any damage. The o2 sensors need replacement at around 100k.
The smoke could be due to bad ccv. If the valve or its toobs are cloged up, the fumes cant escape anywhere...

search for your code in thread title search.

See jfof's sig for ways to fix vac leaks...which is probably why you have a lean code...most common cause.

Take codes from Autozone...not their repair help.

Welcome then.

Use the search option and you will find all the answers.

Ccv is same as PCV on other cars except its much more aggravating to replace then on any other car on planet

Google and search here...

OP, do not listen to the people at Auto Zone, there is a reason they work there, they can look up parts and run the cash register.

As for your problem, most likely a vacuum leak.

Really suggest you read over the first 3 links in my signature.

You also need a scan tool of your own so you can stay away from Auto Zone.

See this thread here - http://forum.e46fanatics.com/showthr...8#post15087698

A few hints, Intake boots, CCV lower oil return hose, DISA O-ring are some VERY common problems.

Run your hand down the dipstick tube. You will find a hose attached to the tube. Follow the hose forward to where it should attach to the bottom of the CCV. I'd be willing to bet you find it broken. Replace the hose(s) on the CCV and you will probably cure your problems. This one is notorious for causing P0171 and P0174 codes. I spent a small fortune before I found this problem.

They're bs'n you with the cat.

Clean your MAF and ICV, check the intake boots for any cracks/tears, check the secondary airpump hoses leading to the f-tube on the intake boot, and check the DISA's o-ring and the DISA itself for noise for starts

P0171 means the car is running lean in Cylinders 1 - 3 (Bank 1, Sensor 1).

Not quite. There are 4 hoses. One from the front of the cam cover, one from the rear, one from or to the intake manifold and one to the dipstick tube.

Check out this thread for the CCV DIY. Maybe it can help you identify what you are looking at.

Vac Leaks are generally global, that is you should get both P0171 and P0174 when there is a vac leak. I don't know the plumbing, and I suppose there could be a leak that would affect the front bank or the rear bank, but not both banks, but I have no direct knowledge of such a leak.

Just giving some food for thought.

This morning it was the light white smoke and was making a crackling noise. I'm really nervous on the pricing and how serious the problem is if it is serious

Tell us the car's history in detail first...miles, when you got it, what you've done already. The list of possible 'smoke' is short...

water vapor, oil, or coolant.

Only serious issue is 'usually' coolant or oil, coming from bad head/head gasket due to a prior overheating incident. If you're not losing coolant, that's good. If oil is 'in' coolant or vice versa, that's bad.

When do you get the smoke? How consistent is it? Try a bottle of Techron and a long drive (1 hour at least)...see what you end up with. That said, I think you should search for your symptoms using title search here. Read until you puke.

It could be just water vapor and you only need to drive it.

Could be clogged ccv and you only need to drive it.

Could be broken ccv--$150 in parts--4 hours diy the first (and probably only time you'll do it).

Don't worry about head/head gasket ($50-2500 depending on what it is and whether you diy it or not...$ are approximate...but probably close!)

Don't expect to get an answer here in this thread alone...you need to do a bit of reading...you need to puke! Sorry...I'm just the messenger!

...and welcome to fanatics, buddy. Don't let me scare you, btw...don't read any of my threads...you'll fn freak out!

All just about how much of a "go-getter" you are....This site is a wealth of information, much more than you'll probably ever need. It's highly unlikely that you'll encounter a problem that someone else hasn't already tackled. Once you narrow down the troubleshooting to the "OK, which parts do I need?" step, do yourself a favor and DO NOT buy ANYTHING from the dealer! Check out BMA Auto, German Auto Solutions, etc. for the best prices that I personally have come across. I've only owned my 2002 325i sedan for a little over 4 months now, and since joining the forum I've been able to find a solution to every problem that I've had - and there were plenty, the previous owner did NOT stay up to snuff with his maintenance! Good luck, welcome to the forums, and keep us posted on your progress!

If you're willing to put some time into it (do google searches and searches on this forum) you can save yourself tons of cash by doing it yourself. Alot of the stuff sounds or seems like it's complicated but again, after reading the DIY's and watching vids, most of it isn't too bad.

Hey Stickbuilder, are you talking about just #4 vent hose or #4, #2, #7 and #3?

Dmax I purchased my 330i when it had 99k. At around 102k miles my coolant tank was cracked and had to replace it. That was the only problem I've had with the car other than replacing the driver side regulator, also I installed a k&n air intake. That is all I've done. Like I posted earlier I did lose oil and at anytime it will have the smoke with a slight burning smell at random times. Most of the time it's just the light smell. Then this morning it started making the crackling noise pretty loud, ran normally. Then as I got back into it 5 hours later it didnt smoke or make the noise. Just smell. I have checked and there no oil In the coolant or vice versa there's so many things I just don't know where to even start it just seems so odd
