The Standard Ignition RY-579 is a replacement relay listed as a computer control relay, fuel pump relay and main relay. It is an electrically operated switch that lets a low-current control signal turn higher-current circuits on and off. It fits many vehicles, among them the 1998-2005 Volkswagen Passat, 2004-2009 Volkswagen Touareg and 2002-2004 Audi A6, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
- Built for under-hood conditions: A high-quality composite housing is designed to protect the relay against harsh temperatures and demanding under-hood environments.
- Certified quality: Made in TS16949 and ISO9001 certified facilities.
- From an OE ignition manufacturer: Standard Ignition is a global manufacturer of original equipment ignition products and maintains quality control across the whole manufacturing process, from componentry to the finished product.
If a failing relay is behind a no-start, a fuel pump that doesn't run, or intermittent stalling, this relay replaces it. Diagnose the circuit first, because wiring, fuses or the pump itself can cause the same signs.

Frequently Asked Questions
What does this relay do?
It is an electrically operated switch. A small control signal energizes it, and it then switches power to the higher-current circuit it serves, such as the computer control or fuel pump circuit.
Will this Passat relay fit my 1998-2005 Volkswagen Passat?
Yes. The RY-579 is listed as a direct-fit replacement for the 1998-2005 Volkswagen Passat. See the "Vehicles it fits" section for engine details.
Is the RY-579 also a relay for the 2002-2004 Audi A6?
Yes. It fits the 2002-2004 Audi A6 and the 2004-2009 Volkswagen Touareg, along with many other vehicles shown in the "Vehicles it fits" section.
What signs may mean the relay needs replacing?
Signs include a no-start, a fuel pump that doesn't run, or intermittent stalling. Wiring, fuses or other parts can cause the same signs, so test the circuit before replacing the relay.
How is the relay built?
It has a high-quality composite housing designed to protect against harsh temperatures and demanding under-hood conditions. It is made in TS16949 and ISO9001 certified facilities.
