Diagnostic trouble Codes P0300 BMW 325i 2002

SOURCE: 2003 BMW 325I Power Steering

when looking at the engine with the hood up, look to the right hand side for something that looks like this (#1 in the pic): http://www.realoem.com/bmw/showparts.do?model=ET37&mospid=47720&btnr=32_0957&hg=32&fg=20

it will be black in color, but don't confuse it with the oil filter housing. power steering reservoir will have a unique cap (#2 in the pic) that can be removed with your hand. the one that has the large nut on top is the oil filter. remove the cap and put in the correct fluid.

hope this helped.

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).

The motor is replaced from under the hood, you have to remove the cabin ai filter housing. It is can be a hard job. Most dealerships will charge 3 hours labor to do it.

all the codes you have are all related to the fuel trim, this problem needs to be looked at with a european capable scanner for futher tests sorry.
