Where is the gas cap release on a bmw 325i

Your question did not specify what "filler cap".
The above response from FTjoe is for the power steering filler cap.

The following RealOEM link is for the engine oil filler cap (Item 4) which is square and black and is on top of the engine. It goes through the plastic cover into the cylinder cover

Lack of every having a tune up will do this. Fuel pump, filters, bad gas, oil cap or gas cap loose or missing, vacuum hose off or hole in it.

Should be under steering wheel left or right side,need OBDII scanner to reset.

The blower motor relay is located in behind the climate control center mounted to the ac box.The window relays are located in the power distribution center under the hood number k-5 and k-7.

I am not to sure but It sounds like you may need to check under the seats for pinched wires if it was on a relay it would probably still work you need to look at the lights on the shift console to see if they light or have power supply first

Push in on door and it will pop out. Make sure the car is unlocked when you do it. If your asking about the emergency actuator release for the door it is in the right side of the trunk. Pull on the green tab.

remove rear seat and look for plastic big round cap

Clean out the blockage in the engine gas recirculation and or idle by pass.Sounds like a blockage or the idle bypass has failed
