Fitment

Fits for:

• MAN TGX / TGS / TGA / TGM / TGL (Euro 5 / Euro 6 SCR / AdBlue diesel applications depending on configuration)
• MAN heavy-duty trucks with Continental / Vitesco SNS3059 NOx system
• Engine: MAN D20 / D26 diesel SCR systems (depending on emissions setup)
• Position: Exhaust NOx sensor (typically inlet SCR or outlet SCR depending on vehicle layout)
• OE Numbers: 51154080029 / SNS3059 / A3C00370600-03 / A3C0037060077 / 51.15408-0029

FAQ

Q1: Are 51154080029 and SNS3059 the same part?
A1: Yes. 51154080029 is the MAN OE number and SNS3059 / A3C00370600-03 are Continental/Vitesco references used for the same NOx sensor family in Euro 5 / Euro 6 SCR systems.

Q2: Where is it installed?
A2: It is installed in the exhaust system to measure nitrogen oxide levels for SCR (AdBlue) emissions control.

Q3: Is this inlet or outlet sensor?
A3: It can be used in either position depending on SCR configuration; MAN uses the same sensor family with different harness lengths and mounting positions.

Q4: What does this sensor do?
A4: It monitors NOx concentration in exhaust gases and helps the ECU control AdBlue dosing for emissions compliance.
