Understanding Track Style Wiring Diagrams, Important Stuff!

What the heck is a "Track Diagram"?
Audi's "Current Flow Diagrams" or track scheme of wiring diagrams is truly one very large view of the electrical systems and components incorporated on a particular vehicle. However, since it would be physically impossible to view all the tracks on one display or page, they have broken this large system into smaller component related divisions. For example, "Battery, Starter, Generator and Voltage Regulator" may be found on "Tracks 1 - 14", and "Brake Lights and Backup Lights" found on "Tracks 293 - 308".

It is very important to understand that track usage may appear to be duplicated or contain omissions; this is not a mistake!.
For example, while "Tracks 1 - 14" under "Engine Specific - Main Wiring Diagrams" may be used for "Battery, Starter, Generator and Voltage Regulator", the same term "Tracks 1 - 14" can also be used for the optional equipment diagrams "Cruise Control" and "Heated Seats", since they represent three separate diagram schemes.




"Current Flow Diagrams" or "Track" style wiring diagrams show the powerflow through all wires, connectors, switches and motors beginning at the top of the page, usually the fuse/relay box, down the page to "ground" at the bottom. If a particular Current Track does not provide all of the "Power to Ground" information about a system or component, continuations and splices, etc. will be shown.
