Question HOW TO and do-it-yourself threads

This page has grown quite large in the last few years. It's main purpose was to put all the helpfull "how to" posts in one section for easy reference. It is becoming more difficult to find things, even in this one thread. So I have edited the thread & divided the "How to's" into categories to make things a little easier to find. I will add more subsections, like Engine maintenance, Performance, ETC. As well as maybe divide the links into models (A4, A3/B4, etc.). But I want to clean it all up first, then get into the little details. I just don't have a lot of spare time this week.

Please, if you have any suggestions for where I placed any of the items, feel free to contact me and I will make the appropriate changes. But please do so through IM's. And to keep this thread user friendly & easy to navigate, please only post links to how to's that you may have done or seen. Please do not post questions or feedback in this thread.

NOTE: This is a work in progress as it takes a long time to do the editing & fixing the links. I hope to have it all done in a few days.


First & foremost, don't forget to look at the ARTICLES link at the top of this page. It has great writeups on such things as timing belt procedures and nozzle swaps.

There is also a section of FREQUENTLY ASKED QUESTIONS that should be looked at.

Now here are some of the How to's compiled by our members:

Early 1999 cars have a different n75 and n18 connector. Here's a link for part numbers to change the connectors to the later style to be able to buy the less expensive units.
