For 2002 BMW 325I a yellow oil light comes on when engine first starts and sometimes at random times then turns off a few minutes later. All oil levels are good. Not sure what this means and how to fix it?

Scan for codes--see what is applicable

The first trial. Switch on ignition. The engine oil pressure warning light for thered light. Start and run the engine, warning lights, half a minute later re lit, butthe Yellow state. Repeated tests a few times are so. Turn off the engine. Pull out the dipstick check the amount of oil, the normal. Self diagnosis to connect to the GTl diagnostic instrument, choose 3 E46 chassis models, click on the"test" button, the scanning of the electronic control system of the whole car.After click two times right. Enter the fault code list interface, can be seen in the"KOM combination meter" project. The store has a fault code.then use the obd code reader to check out it.

The first thing to do would be to check all fuses. Sometimes a very random blown fuse can cause this. Also unhook the battery for one hour to reset all systems, and try a jump start if you have not just to be sure it isn't a battery issue. Also try locking/unlocking the key driver's door a few times using the key in the door. If the fuses are good and the battery reset does not help, nor a jump or key in the door, then there are a few other things that can cause this such as bad key - try another one, bad brake light switch, the switch is above the brake pedal, shifter not fully in park (auto transmission only) - try moving it around a bit, bad transmission position switch, bad clutch switch, dead starter/solenoid/relay or bad ignition switch/cylinder/start button.

Sounds like a shorted or sulfated battery to me.

That light for oil temperature and level , sensor on the bottom of oil pan may be going out , it's common.

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).

It needs a new fan control. $80 online and 20min. labor. I just replaced mine in the same car.
