Detailed Description

Standard Ignition RY-771 is a computer control relay designed for BMW vehicles that require a 4-terminal relay with spade terminals. It is commonly used in electrical and body control circuits where reliable switching is needed at 12 volts and up to 30 amps. This part number is also referenced as RY-771, making it easier to match against service information and replacement catalogs. Compatible BMW applications include 2000-2007 BMW X5, 2004-2007 BMW X3, 2001-2006 BMW 325Ci, 325i, 325xi, 330Ci, 330i, 330xi, and M3, plus 2001-2005 BMW 320i and 1997-2000 BMW 528i.

What It Helps Address

• Intermittent relay operation in BMW electrical circuits
• No-start or accessory power issues caused by relay failure
• Loss of control to a switched electrical load
• Heat-related relay contact wear in 12-volt systems
• Faulty relay switching in BMW 3 Series, X5, and related models

Installation Notes and Tips

Verify terminal layout, amperage rating, and connector style before installation. This relay uses male spade terminals and does not include a connector or mounting bracket, so the existing harness and relay cavity must match the 4-terminal configuration. Confirm the vehicle application against the exact BMW model and year, including 2012 BMW 760Li, 2006 BMW M5, 2006 BMW M6, and 2000-2003 BMW Z8 where listed.

Quality Assurance

Standard Ignition supplies replacement electrical components for service and repair applications. RY-771 is built to match the specified relay format, electrical rating, and terminal configuration for the listed BMW fitments.
