Removing and installing seat occupancy recognition (USA) — AUDI

🧭 Before you start

Disconnect the battery, remove the passenger seat and mount it on VAS 6136, take off the backrest, cover and padding. Free G452 from its bracket and lift the mat, padding, sensor and J706 out through the seat pan without unplugging anything. Fit the new kit the same way, smooth the fabric layer, clip the mat, attach G452, bolt J706 at 2.5 Nm, refit cover and seat, then run the airbag function.

Fits: Audi A6 C6 (4F, 2004–2011)

Don't miss

• The service kit is pre-calibrated; never unplug connectors (3) and (7) or any kit component.
• Do not bend or kink the pressure hose or the sensor mat while working.
• Reuse the old solid foam insert; it is not part of the service kit.
• J706 bolts take 2.5 Nm.
• Run the Airbag function in Guided Fault Finding after the seat goes back in.
