Trying to hunt down elusive P0442 code on my '98 Golf III.
As of yesterday I swapped out the gas cap, but if I remember correctly, this did not resolve the issue previously.
I have visually inspected as much of the vacuum tubing as I reasonably can. I ran the car and sprayed nearly ever inch of vac tubing that I could see with carb cleaner and didn't hear any stumbling or alternation to idle. I think this is a good thing.
This is the only persistent code on my car and I need to get it inspected.
I've done a lot of reading and know that I should check the Leak Detection pump and perhaps the Purge valve. Where can I find these on the car? Several months ago I had intermittent no starts and the garage I took it to said they cleaned/blew out the purge valve, but my code continued to persist, and they didn't fix the no start either. No start ultimately turned out to be a flaky alarm.
One source said LDP was under right rear fender by gas fill tube. That didn't pan out. There's a vac hose on the front side of the gas fill tube, and it looks like it connects to a vac port that enters the rear side of the fill tube by the gas cap.
Anyone have a picture of definitive location for LDP and purge valve for a '98 Golf III mexican made?
