Code PO340 "Camshaft Position Sensor Circuit Malfunction". Now that does not mean that if you simply replace the sensor your problem will be solved. It can be simply loose, cut, or corroded wiring. It can also be something entirely different. This is where diagnostic skills come in.

Bmw 2882/3 fault codes present

You most likely have an engine vacuum leak or a defective mass airflow sensor or low fuel pressure. Read the codes with a OBD2 code reader and see what the standard codes are.

2002 bmw 325i engine light is on

All I know is that it is a 9 year old BMW. Probably has a little over 100k miles on it, right?
I would give better than 50/50 odds that a check engine light is telling you that your oxygen sensors are approaching the end of their service and are getting slow to respond. If you read the codes (which many auto parts stores will do for free) and the code says 'Catalyst efficiency low', the problem is old oxygen sensors.
You can replace oxygen sensors yourself if you have ramps to raise the car up.

Check engine light is on service codes p2231 p1418 are active . 2004 bmw 325i m56 engine


The code you reported does not seem to have relevance for BMW. Often generic OBDII codes do not have meaning and in this case the fault code does not correlate with any reference tables that I am using at this time. If you can have the car scanned with the BMW proprietary software and revert with those codes, it might shed light on this issue.

Let me that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Checkenginelight came on tonite on my 2003 bmw 325i I also tighten my gas cap to be sure it wasn't that was causing the light to come on.

What you need to do is have a shop pull the CHECK ENGINE LIGHT CODES from tne cars computor. Once codes are known the diagnostics proceures must be perform to determine what of the engine circuits caused the light to come on. Once repairs are done then the CHECK ENGINE LIGHT can be reset.

Check engine light comes on but car runs great 2002 bmw 325i and

The check engine light could be any number of things and the only way to find out is have the codes scanned. The brake light issue is common on E46 3 series. It is an issue were the brown ground wire that goes into the lamp housing melts at the connector causing a loose ground connection. The connector needs to be replaced and also add additional grounding wires to prevent further issues. And for fuel additives either use the cheveron techron, or the bmw fuel additive(the bmw stuff is the exact same thing, so just use which ever is cheaper).
