FAQ

Q1: What is this NOx sensor used for?

A1: It measures nitrogen oxide (NOx) levels in diesel exhaust and sends data to the SCR system to control AdBlue (DEF) injection and reduce emissions.

Q2: Is 5WK96756A the same as BMW OEM parts?

A2: Yes.
5WK96756A is a Bosch/Continental reference number used as an OE-equivalent NOx sensor for BMW diesel SCR systems.

Q3: Is this an upstream or downstream sensor?

A3: This listing is typically used as the upstream (pre-catalyst) NOx sensor, but exact position depends on vehicle model and exhaust configuration.

Q4: Which engines use this sensor?

A4: Mainly BMW M57, N47, and N57 diesel engines across 3 Series, 5 Series, X3, and X5 platforms.

Q5: What are common failure symptoms?

A5:

• Check engine light
• SCR/AdBlue system warning
• NOx signal error codes (e.g., efficiency faults)
• Reduced engine performance (limp mode)
