FAQ

Q1: Are A0111536128 and SNS3042 the same sensor?
A1: Yes. A0111536128 is the OE reference used in Mercedes/VW-related SCR systems, and SNS3042 is the corresponding NOx sensor module designation used across multiple OEM platforms.

Q2: What vehicles use this sensor?
A2: It is commonly used on Volkswagen Crafter and other commercial diesel vehicles with SCR (AdBlue) systems, often sharing components with Mercedes-Benz-based platforms.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream or downstream NOx sensor depending on exhaust configuration. Many SCR systems use identical sensors in multiple positions.

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