The gas cap on my 2004 passat will not open - 2004 Volkswagen Passat

if you can get it on a lift id check from your tank and follow all the lines up to your block, checking for leaks. does it smell like burnt gas or raw liquid?

IS YOUR PROBLEM SOLVED?

PROBABLY FAULTY SWICH BUT NEED MORE INFO

That would most likely be caused by the gas cap not being tight, the gas cap being worn, or an evap problem with your fuel system.

run the fault codes and look for PCM bus communication problems
could be a bad ground problem

replace batteries in remotes and reset system.(once you have changed batteries if you get a problem get back to me...)

they just guessed it was a gas cap. gets expensive when you play the guessing game. They are not suppose to sell parts based on codes. Parts stores have been warned against this. It could take up to a month to turn the light off on some cars. If the problem doesnt clear up then you may have another code come up but since the light is on already you wont know it

biggest reason for a check engine light coming on is gas cap not properly seated. I think you have you own answer. (((SMILE)))

if you can some how manage to get it opened, spray some lubracant on the button inside the door. if not you'll need to replace the release cable.

Hi

If my memory serves me right, the solenoid which pulls the cable to open the gas cap door is in the trunk on the side wall. Just gain access to it and then operate the plunger by hand. If you have one of those net storage bins fitted then you may need to remove that first as it could be behind it.

If you want to diagnose the problem, you need a volt meter to trace if, and where the voltage is missing.

Very best regards
