Tech Articles

Welcome to the AudiWorld Tech section. Since 1996 we have written and collected articles containing specific information about do-it-yourself maintenance and other hard-to-find how-to tips. While we generate our own technical articles from time to time, AudiWorld Tech articles are generally based on the experiences of our readers. If you have performed specific upgrades or modifications to your Audi or have information that you believe should be shared with others, then you are strongly encouraged to submit that information for a Tech article. Submit articles by e-mailing to

Also, be sure to check out the topic specific Technical pages:
General Audi, Electrical, Engine, Interior, Exterior, Wheels and Brakes (also covers suspension) and Miscellaneous. Note that while this page is updated often with recent submissions, the topic specific pages are archives, content is generally not removed.

Readers are advised that Tech articles are for informational purposes only. No liability is assumed by either AudiWorld or the author for the use or interpretation of information contained within an article — all decisions based on the data or information are the responsibility of the individual user. See the AudiWorld Terms of Use for more detailed information.
