Question about BMW 330

1 Answer

Shortly after filling my tank with gas, the check engine light went on. I thought it was probably the gas cap, so I pulled over to tighten the cap. The cap wouldn't budge! There was a gentleman nearby, and he couldn't budge the cap either. I drove the car home and put it in the garage, still not able to open the gas cap. The next morning, I was able to open the cap, so I removed it and resealed it. This was 2 days ago and the check engine light is still on. Do I need a new gas cap?

Hi,
You definitively need a new gas cap. Cap apart you may have a vacuum leak or other vacuum related problems.
You can try resetting the engine light by disconnecting battery cable for two minutes, however the car computer module should be scanned to read error codes and find out any eventual fault related to your recent problems.
Regards.

My check engine light came on shortly after filling my gas tank. I did put more gas in the tank after the gas pump clicked that it was full. what could be the problem


If your check engine light came on shortly during or after filling the tank, and then goes off later, thats quite a relief. It really happens, and lucky for you dont have to bring your vehicle to a shop if the light persisted. Here are some tips regarding this issue: turn off the ignition switch before opening the fuel tank cap. Turn on and start only after the caps are properly closed. The scenario is that, whenever we refill gasoline on the tank, the pressure and the vacuum inside the tank are being upset, sometimes creating some kind of signal glitch which may be misinterpreted by the engine control module, and thus shortly illuminate the check engine light. I hope this lightened you up. Have a safe trip. : )

My check engine light came on shortly after filling my car with gas. I tightened the gas cap, now how do I reset the Check Engine light?


Well in the newer cars you cant have the car running when filling the tank.

Take it to either advance auto or autozone and they will have a scanner. Tell them you dont know what the code is. Watch how they hook it up.

They will let you borrow it, but for what they say are "liability reasons" they wont clear your codes. Just hook it up and use the scanner. Really easy, menu driven device. And it will save you a bundle compared to what the dealer wants I'm sure.

Check engine light came on after filling the car with gas, after going from shreveport la. to dallas tx.after tightening the gas cap it went off what should I do?


A loose gas cap will cause the check engine light to come on as it is part of the evap system. Tightening the cap is the solution, which you did.

Everything is fine...now worries.

Tighten Gas Cap Error Message


seems that your vent hose on the tank is plugged so the tank is over pressurrizing sending the error code and not allowing you to fill it all the way unclog the vent tube and this will solve the problem

Check the fuel system relay and or shutoff valve. Probably the relay located under the hood. relays will not contact properly sometimes. especially if you hit a bump and the relay loses connection. Another solution may be that your fuel pump is just about to go. it is making it's last efforts.

Check engine light


Sorry your going to have to change the gas cap. You can try  spraying WD-40 to the rubber seal on the gas cap to get you some more months out of it, the seals get hard and don't seal any more. Good luck

Check Engine Light Comes on Intermittently


The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.
