My 2000 1.8 Turbo has been difficult to fill with gas. The gas door release won't open the door. I can hear the servo try, but the door does not release.
I dismantled the molding inside the rear wheel well in attempt to get to the source but it wasn't the right spot. I could see the cable and housing go into the gas filling area, but couldn't do much from that angle.
I removed the molding inside the trunk by the hatch release, then the molding next to it. I had to remove the molding that goes up the rear pillar first. Some peices have screws and others pop right off.
After I removed all the molding, I could see the servo (off white) and the cable. I removed the servo and pulled the cable back into the trunk compartment. I pulled on the cable and discovered it was not sliding very easy. I pumped some WD40 into the casing, let it soak a while, then worked it some more. I ended up taping a funnel to the cable and housing, filling it with WD40 and let is soak in. That did the trick. The cable moved a lot easier.
I resembled everything and am crossing my fingers that it will continue to work.
This is an hour or so job.
