    Thread: Gas Cap to Engine warning light

    1. 06-15-2010 09:59 AM #1
      My gas cap warning light came on this morning, I thought I would fill the car in case the cap is loose. After the car was refulled to the max, the car just started, spluttered for a few seconds as if it was going to stall, then after a quick rev it ran fine to the office. The gas cap light went out, but just before I got to work the check engine light has come on.

      Is this a sensor breaking down or something serious?? I only have 16k miles

      Had the identical process happen on Saturday morning. While on my way to fuel up my gas cap light came on, then after fuel up same thing. Start up rumble then it died, but everything was fine after the second start up and has been good since. If it gets persistent I will take it in. 23k mile.

      Have either of you had the gas tank recall done?

      Yes I have, almost a year ago with no issues. I am not sure why this little glitch happened but I haven't seen any ill effects from it or performance loss.

      Me too, I had the recall done September (or there abouts) last year, since then the fuel pump needed replacing in January. I don't think this is associated with the gas tank recall......If two of us have this problem, there must be others??????????

      I haven't had a check engine light so for now I am going to rule out any codes being stored in the system. But if it happens again I am going to take it down to the service center and get it checked. Until then I will keep motoring on.

      I've had this happen as well, and have also had the gas tank recall performed.

      I notified my tech at the dealership during the mechatronics unit replacement that the gas cap indicator will come on, sometimes followed by a check engine light. He responded with, "oh yea that will happen, it should reset after 5 or so cycles.... let's keep an eye on it"


      Either the gas cap seal is allowing a vacuum problem ( i hear the sensors are extremely sensitive ) --- but the techs' said they tested the gas cap with no problems found.... OR there is some issue with the fuel evap system allowing for a leak elsewhere...

      Sometimes I drive weeks at a time with no lights on... but this typically occurs after a fuel up. Also maybe related, after every single fuel up the car will sputter when starting at the station.. I have to give it a bit of gas that time and it is fine until the next fuel up.

      The sputter you guys are talk about happens to me in the opposite way. everything that I need gas the car has a hard time starting up and after a fresh full tank it will start up perfectly. I think this has to do with the fuel pump cycling the fuel.

      Just this morning had the gas cap warning light come on. Left car running, opened and resealed gas cap, light still on. Turned off, then on engine and went away.

      Wehrmacht what info are you looking for? tighten your gas cap.


      it should go away shortly.

      if not, you have a faulty gas cap and or need to bring it in for further inspection. if your car is still stuttering after the recall.. you need to bring it in.. it needs attention.

      I have had 2 gas caps replaced and the recall done, and still get the Cap-light to check engine, then clears on it's own. My cap light came on Monday, and I took a trip to the dealer and a small leak has been detected, that is the code reading.

      Now where is the leak? my friend and I are working on it, which means I am going to throw my own money at it, and if I find the remedy VW WILL reimburse me on a warranty issue and I can pass the fix on to the forum.

      I recently had the gas cap replaced - it was loose and could not be tightned. I placed a soft sponge between the cap and filler door. Thick enough to keep pressure on the cap when the filler door was closed. This corrected the problem (light went off) until I found time to go to the dealer for repair. A simple way to find out if it indeed your cap


      Cheers

      Within 5 mins after starting the car in the morning I would get the gas cap & check engine warning light. The only way I could get rid of the check engine light was to fill up the tank and the light would go away. Just loosening the gas cap and then retightening it wouldn't get rid of the light.

      When I took it into the dealer it was found to be the Evap Purge Valve. This is what was on my repair order: During inspection traced fault code P0456 tank ventilation system leak detected. Performed smoke test and verified leak from the purge valve; replaced listed part as needed. Rechecked and road tested OK now.

      All this occurred after I had done the gas tank recall. I haven't had a faulty warning light since this last repair.

      You must take me for an automotive-idiot... the issue is clearly not so simple. I know how to rebuild top ends of straight 6 BMW's, let alone screw in a damn fuel cap. Thanks for a value adding response...

      Thanks Drew... I'll look into that.

      whatever your name is, I think you took this the wrong way.. or my text is not as eloquent as I would imagine..


      I was only trying to help the gas cap issue has been around for years... and screwing it in helps.


      and yes, the issue is that simple.

      good luck with your ventures sir
