Detailed Description

VEMO focuses on OE-style electrical and emission control components, and the V10-76-0017 follows that approach with the connector style, wiring layout, and thread specification needed for the rear right post-catalyst location. This oxygen sensor is listed for 2002-2004 Audi A6 Quattro rear right, 2002-2005 Audi Allroad Quattro rear right, and 2004-2009 Audi S4 rear right applications. The part number V10-76-0017 also cross-references Delphi ES20177 and Walker Products 250-24493 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect post-catalyst air-fuel feedback readings
• Emission test failures tied to sensor performance
• Damaged connector, wiring, or sensor thread issues
• Replacement needs for OE number 078 906 265 AA

Installation Notes and Tips

Verify the rear right position and OE number before ordering. Confirm the connector shape, 4-wire configuration, and M18 x 1.5 thread match the original sensor. The thread is pre-greased, which supports installation, but the sensor should still be torqued to the vehicle manufacturer’s specification. Check cable routing and exhaust clearance during installation on Audi S4, Audi Allroad Quattro, and Audi A6 Quattro models.

Quality Assurance

VEMO supplies OE-style emission control parts built to match the listed application details, including connector type, circuit count, and fitment references for confirmed Audi rear right use.
