Hopefully you remember my post about a supercharged 323ci... anyways I looked at the car again today. The guy selling it backed out initially but it is now on the selling block again. When i test drove it, two things that kind of raised an eyebrow.
1) After driving it for about 10 minutes at around 60-70 km/h, we hit a light. The car sort of stuttered while it was idling... Almost like it wasn't getting enough fuel or air... Anways the guy said it did it at times, but I shouldn't be alarmed... Is this true? does the idle tend to dip? It dipped from around 9000 and kind of bounced back and forth between 7100-9000... Once it was green, i tried to hit the gas she kind of stuttered... it seemed very odd to me... or is that normal because of the pulley being used by the SC...
2) About 30 seconds, the car's engine light came on? He said this had something to do with emissions or something? He did mention he pumped 91 octane in the car. Shouldn't it be taking 94?
Anyways, he said he brought it to Eurasia to get it looked at and everything looked good... He even has the paperwork to prove it, so I was just hoping someone could shed some light on the scenario and what all that could mean? If something is wrong, why didn't Eurasia pick up on it...
Not too great with my SC lingo so i apologize for the subpar description... Any and all help is greatly appreciated...
picture of the vehicle up for grabs...

You raise some valid concerns. First thing I need to ask, is what do you mean it jumps from 7100-9000 RPM at a stop light? The engine shouldn't be revving that high.
And if the Check Engine Light is coming on, then obviously there is something wrong. It could be as simple as something to do with emissions, but my suggestion would be to take it somewhere that has a code reader and can tell you want code its throwing.
As for what Octane it needs, 91 is completely fine. Even fairly highly modified cars can and do run on 91 octane.
I would be cautious of this car until you can get those questions answered.

I presume he means 710-900.
But if it is revving 7100-9000...I wouldn't buy it lol |

it took off good but sounded funny to me but didnt think of anything till i saw this post
just letting u guys know :) |

| i would definetly get it checked out before you make a purchasse even on new cars i like to get it fully inspected before i buy, because u never know what little things could be wrong on a car like that, that really add up. good luck on the purchase sweet looking car. i hope it works out for you. |

why do people rush to conclusions. at idle if it dips down to 700rpm and back up to 900-1000 normal rpm its probably a spark plug or wire. i had the same problem and it turned out to be just that. bad spark.
if your worried, take it to a shop and get the codes checked. if it is just emissions it will show up in a second and anything else missed will show up as well. i would recommend getting the compression test done at the same time. |

| was the car fully warmed up when the idle was fluctuating between 710-900? Mine will bounce a bit while its in the final stages of warming up because the computer can't quite decide if its still in warm-up (higher idle) mode. |
|

| Prudz_lude |
| even if it was and had bad spark it would still idle like described even at normal operating temp |

| definately a nice car! dont rush into the sale though without doing more research! Get your codes read, and speak to your mechanic specifically about the issues you had during your test drive. |

Does he still want $30000 for it?

check engine light could be just something dumb like an o2 sensor or emission sensor on the cats..( or lack of cats)
idle blurp might be just a shitty tune or crappy engine management unit )split second box or something?) |

edit: or a bad camshaft sensor.. as per that thread you posted heheh |

im that guy who worked on this car from eurasia...! this car has a AA tuning rotrax supercharger kit on it... installed by a bmw dealer in vancouver, the dme was reflashed for the kit, however there is a huge issue! it runs rick at idle, ( big injectors) the dme cannot lean it out enough for emmission reasons so its shutting down cylinders, hense the rough, really rough idle its putting the motor into a " limp" mode.. this is one of its problems, the other is that it goes extremly lean on boost, it maxed out the air/fuel guage in the car, thought it odd but wouldnt think it was a valid source of info but the egt's were maxed out too..!! i couldnt beleive how poorly this car was running, i actually took it to the dealer and scanned it...the adaptions were reset and everything cleared, the owner didnt seam to care that it wasnt fixed, just that it didnt idle rough anymore... this car looks the part, but a standard E46 323i is actually faster...
just thought ide give everyone the actual facts on this one!! |

| Wow if hughX2 really did work on this one, sounds like you got a nice inside word on the car. Wouldn't AA have a fix for these problems as thier kits are pretty well thought out. I would have thought they would have seen this kind of thing before on test cars. |
|

| hughx2 |
| yah, i called them they said they have no problems with the kit/ software, and it should be running fine... so they said they might of just been blowing my off but thats what i was told... this is not an isolated problem alot of the supercharged bmws in town on this era have many of the same prblems, im really trying to figure it out.... most time people just dont want to leave them for the time its needed to work thru these problems!! even the big buck dinian kits are causing problems!! ill nail it down soon, its only a matter of time and money!! |

| sounds like these things need a better engine management system than just a reflash |

| trying to crack a bmw dme.. it would be easier to break into fort knox!! i had a m roadster come in, very fast!!!! it had a piggy back fuel managment system on it, it ran great!! had a problem with the last guy forgot to tighten up the s/plugs, hahah.. but same model 2 weeks later came in same management kit and the dme was randomly shutting down cylinders becuase it was running too rich!!! i would say go with another managment system but thats just going to compond the problems !! and the stock dme does so much for those cars drivability...currently i think the problem lies in the " upgraded" software... it just plan out doesnt work, or they messed up something.. an aftermarket ecu might be the answer but you have to consider the amount of controls it will need, with the double vanos, electric throttle control, etc!! not impossiable just alot of tuning to work out the bugs.. oh funny side note, the owner of the e46, anctually wanted a quote to remove the kit.. haha apparently, "its too fast..." hahahah i think he should know thats its really slow for what it is... if anyone has any SOLID thoughts please feel free!! |

Update: Monday the 28th of May
It seems to be an O2 sensor. At least that was the code that shot back. Alex from Modern will be working on the car. Maybe some of you know him. he has done several projects in regards to supercharging BMWs... mostly E36s but he has some extensive knowledge when it comes to superchargers.
So no sweat, the car is fine... the Supercharger is fine... the rough idle is being caused by the o2 sensor which is a common occurence with E46s... car should be running fine once i get all that panned out... a costly fix but hey, it comes with the car...
I am still learning about the car and such so hopefully in due time I could work on it myself...
thanks again for all the feedback...
Cheers!!! |

You should see how expensive o2 sensors are for bmw's.. that and the fact that there is 2 in the back.. and 2 in the front of the exhaust. Model dependant of course. |

O2 sensors are pretty generic. There shouldn't be anything relating to the running of the engine at the back end of the car. The only O2 sensors that your car shoud have will be close to the engine. Either off the headers or downpipe/collector.
If you are paying more than $100 per sensor, you are getting soaked, and $100 is top level. |

So.. what exactly are you implying in your post? That you think you can get bmw o2 sensors for $100 max? and that there is only 1 next to the downpipe? |

O2 sensors may be a cheap fix on generic vehicles, but I called Bavaria and the two sensors go for 230 plus tax/per sensor.
So yes i think it is going to be a fairly expensive fix. But I am getting a deal on them. 160 each.
There are 4 altogether... 2 front ones and two near the cat...
rythex- yes you were right dude... should have had an online bet going... haha

Holy fuck!:eek:
I'm glad I drive a Neon!:lol: |

| Maybe it's just emissions that's screwing up the O2 sensor, maybe a cheap fix would be to put a non-fouler on it? |

it is actually a common issue with the e46 series... I am not sure if it is strictly the e46 series, but it could be an issue with the other classes as well...
Basically to sum up, it comes with driving the car itself, so it would be no different than other e46 owners... |
