I have bmw 318 08 reg problem is indicating engine fault. Loss of power can u solve this problem.

Hi Anon
To find out what the problem is, you will have to get the code read as this will indicate what the fault is, when the engine management light comes on it could be 1000's of different things, so each error has its own code, you will have to take it to a garage or dealership to enable them to connect a diagnostics reader to your vehicle, reduced power is telling you , you can only drive it slowly as there is a fault and it is not 100% sure what the fault is ( car computers are not intelligent they just know something is wrong ) so it is saying reduce your speed until the fault is fixed. hope that halps

The "service engine soon" light


A code P1092 for your vehicle says the fuel trims are trying to add fuel and the limit has been reached and this throws this code. More specifically Pre-Catalyst Fuel Trim Too Rich Bank 2. A rich condition could be caused by several things. You could have a faulty fuel pressure regulator, a leaking fuel injector or a clogged air filter. I would check the air filter to see if it needs replaced and have the code reset. If it comes back on then you will have to go to a technician and have them pull the actual BMW fault code with their scanner.

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!!
