2000 BMW 323i Check Engine Light Problem-10 codes!!! Help!
Hello, I recently bought my BMW. The Check engine light came on. I had it tested, it came back with 10 faulty codes. I just replaced my spark plugs and wires. Power seemed to be restored. I went to erase the engine codes and drove around for about 10 minutes and it popped back on again with the same 10 codes as before.. I need some serious help?! My friend that's a mechanic thinks its an o2 sensor or a vacuum leak, maybe both. I also contacted BMW and showed them the codes. They assured me that normal driving will not effect the problem or make it worse.. Is this true?

I would first check for a vacuum leak. Common areas of intake leaks are: 1. The crankcase vent valve located under the intake. 2.Check the intake boot at the throttle housing. You will find that there is an elbow where a small hose goes to your idle valve. Using your hand feel in the elbow area for a hole in the rubber. Your tech can use brake cleaner and spray the intake to check for leaks or use a smoke tester. 3.Possible failing Mass Air Meter.At idle, in park, and a/c not on the meter reading should be appr. 18-22 hz

1. Check the fuel lines, ASA FPR first. 2. Check all the hoses. Check for leakages. 3. Reset the codes and go test drive. 4. If everything is ok for the next 80~100 miles or so, work on getting a set of Densos.
A misfire doesn't imply you need new sparks right away.
this could be due to low oil. you need to check your oil level. if it is full i would do an oil change with a bmw filter. there is a difference in filters. the service engine soon light will have to be diagnosed. meaning pull codes to point you in the right direction. great car though. happy holidays
you can buy a cheap scanner that will put this light out,i have a mechanic working for me that stands on the roof ,tweeks the radio and has one foot on the brake whilst turning on the lights and he puts out nearly every service light you can think of but he wont show anyone least of all me,but if it its a 99 model iam sure you can put the light out by using a 12v electrical screwdriver with the light inside and a cable comes out the end with a clip .then going across the pins on the special BMW connector block it will go out with the resistance of the bulb across it ,but ??big but ?does it have an OBDII connector or the round BMW type because we dont have OBDII on pre 2005 cars here in spain .Now we do and guess what ??its all encrypted software used ...makes me a dinasaur
