This was in the moderation queue as it was posted in the FAQ section. Moved to the MKIV discussion forum.

If you don't mind me asking, are you sure you did the diagnostic check correctly? Ime, every time I've seen the red triangle with the exclamation mark, I've been able to read a code.. Codes come up for a large variety of reasons. Anything from a vacuum leak to a bad sensor could be causing it. We really need the code to do the troubleshooting...
