    Can anyone steer me in the right direction on what to look for fix or bypass or whatever the radiator blinds on my girlfriend's 2006 330xi that just failed emissions because of that feature not functioning? Any help would be appreciated I sent a screenshot of the scan which was done with a very...

    After taking a break from my E46, I'm on to getting it re-smogged, as required in CA. For a year, I ran the EU2 tune I flashed, which basically ignores all emissions faults, which left me a small pile of issues when I flashed back to the US tune. So I have some questions first and foremost...

    Hey what’s up guys, just purchased and 02 6 speed m3 and I’m having an issue with the code p1434. I did some google research on it and I heard some people did the DMTL pump but I just wanted to make sure I’m doing the right thing by buying that part, I’m getting a gas cap today hopefully that...

    Hi all, just purchased a 2004 330i ZHP with 198k miles. No check engine light, but when I went to get my emissions test I failed due to all 5 OBD flags they check are showing not ready. I bought the car, then immediately drove 500 miles, so I figured the drive cycle would be good even if there...

    Hey everyone, so my 2002 325i can not pass emissions due to the O2 and catalyst sensors not being ready. When I first took my car for the test I had 4 modules not ready, but after doing the drive cycle I am down to 2. Also, my SES is on and two codes are being brought up (P0491 and P0492) but...

    I own a 2004 325xi BMW. I recently bought this car and the check engine light went on. I took it to autozone and the code said my evap purge valve was faulty. I bought the purge valve online and began to replace it. When i was removing the thinner hose from the back of the old purge valve i...

    So the other day when I was replacing my upper and lower intake boots, I noticed a hose that looked like it was cut/broken/missing. I have no idea what it is or to what it's supposed to connect. I do have an CEL for emissions which may or may not be related. The line is located near the...

    So I've been trying to pass smog for the past month. I recently got my 02 sensors changed in my 2003 330Ci. I took my car in for smog and they said my monitors were not complete. I hooked up my OBDII reader and found that my EVAP, oxygen sensor, and oxygen sensor heater monitor were all...

    Hey Everyone - if there's a "definitive" answer that everyone can agree on somewhere, by all means, please point me there. That being said, I've done a reasonable amount of searching on CCV deletes and have found a fair amount of opinion, and a number of DIY jobs, but no generally accepted best...

    This is the BMW E46's computer/monitor reset procedure. For those of who have the "service engine soon" light coming on frequently preventing you from getting the sticker, read this. If you can get your car to pass this test once without the light coming on, bring it right to the mechanic and...

    Okay everyone, I have had my 2004 330ci since February and it has been fantastic on every level to drive. I bought it for a super low price and everything seems pristine but, the previous owner didn't give it the TLC a Bimmer deserves. Over the course of driving it a month I have had lean...

    Hey, I looked around and couldn't find great advice for my situation. My 03' 330ci has an issue with the catalytic converters. Sometimes the CEL comes on, and I've had the codes read, efficiency banks 1 and 2 I believe. Other times, it stays off. It goes on and off every few weeks. I'm in...

    I've had my O2 Sensors reading "Incomplete" for quite some time and I doubt any of the previous owners changed them so I changed all four (Pre and Post Cat) and still have the Emissions Readiness Reading "Incomplete". I'm using Pro Torque with an ELM reader Is there a method to reset this the...

    Ok so I'm looking to hear if anyone has any info. The M56 SULEV engine has a hydrocarbon filter built into the air box as a part of the emissions system. This to me says "restriction" removing it would be simple enough however would mean you can not replace it in the future if needed. The one in...

    Was running lean. Did some fixes and cleared codes. Drove car about 60 miles or so (local and highway driving) to complete drive cycle (or attempted to). The emissions readiness says complete, but is this all that I need to get my car inspected for emission? Does this mean it'll pass? Thanks...

    Service Engine light came on and it ended up being the code P0411. Looked it up and it is for Secondary Air Injection Pump? I know this is an issue for emissions but does it cause any other harm on the performance or the engine. Basically, is this something I need to get fixed right away or...

    *ROUGH DRAFT* 10.11.13 -- 0.9 10.11.13 -- 0.9.1 - added State Inspection OBDII Reports section *This write up (software versions, variant codes, etc) applies to MS43 M54B30 equipped E46's for now. Most of you know it is now possible to flash different exhaust emission standards. However, what...

    Hi all, I'm reaching a dead end with trying to find out why my car seems to be using too much fuel...and hope someone on here can advise me on what could be causing it. Firstly my car is a UK model 1995 E36 2.0 with the M52 (6cyl) petrol engine, with vanos on the intake manifold. The engine...

    I never post, but this is a juicy one I really want to get out there. So I'm trying to register my '04 in California for the first time with 46,000 miles on the odometer. But I can't because she's blowing too many hydrocarbons. 71 PPM to be exact. I tried race fuel and injector cleaner and the...
