Fitment

Fits for:

Audi A6 C8 (4K) 50 TDI / 3.0 TDI
Audi A7 4G / 4K platforms (diesel SCR variants)
Audi A6 Allroad C8
Engine: VAG 3.0 TDI diesel engines with SCR (AdBlue / DEF) system
Position: Exhaust NOx sensor (commonly SCR downstream / Sensor 2 depending on setup)
OE / Cross References: 4K0907807G / 4K0 907 807 G / SNS770 / SNS770A / A2C14212100-03 / 4K0907807E / 4K0907807AJ / 4M0907807AK / VW/Audi NOx sensor family

FAQ

Q1: Are 4K0907807G and SNS770 the same sensor?
A1: Yes. 4K0907807G is the Volkswagen/Audi OE number, and SNS770 is the Continental NOx sensor reference used in VAG SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Audi A6 C8, A7, and related 3.0 TDI diesel models equipped with Euro 6 SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: Typically used as SCR downstream (post-catalyst / Sensor 2), but exact position depends on exhaust configuration and ECU setup.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends data to the ECU, which controls AdBlue dosing to reduce emissions and maintain SCR efficiency.
