Mercedes Sprinter Upstream Oxygen Sensor – Bosch OEM | BlueTec OM642 3.0L | #0065424918 (2010–2022)

DESCRIPTION:

A failing upstream oxygen sensor on a BlueTec Sprinter doesn't just trigger a check engine light — it disrupts the entire emissions control system, including SCR and DEF dosing logic. The ECU depends on real-time upstream O2 data to optimize combustion and emissions performance. When the sensor drifts or fails, fuel trim suffers, emissions fault codes stack up, and engine efficiency drops. This is the genuine Bosch OEM upstream oxygen sensor specifically designed for 2010+ BlueTec NCV3 and VS30 Sprinters with the 3.0L OM642 V6.

What This Part Does

The upstream oxygen sensor monitors exhaust gas oxygen content before the catalytic converter, feeding the ECU precise lambda data for air-fuel ratio management and emissions system control. On BlueTec diesel Sprinters, it also plays a direct role in supporting the SCR emissions reduction system — making sensor accuracy more critical than on non-BlueTec applications. A failed or drifting sensor causes the ECU to lose accurate feedback on combustion quality, leading to fault codes, reduced efficiency, and potential emissions system cascade faults.

Common Symptoms of a Failing O2 Sensor

• Check engine light with oxygen sensor or lambda fault codes
• SCR or emissions system fault codes occurring alongside O2 codes
• Reduced fuel economy
• Rough idle or hesitation under load
• Failed emissions test

2010+ BlueTec vs. Pre-2010 — Critical Distinction

This sensor (0065424918 / Bosch 17200) is specifically designed for 2010+ BlueTec Sprinters with the OM642. Pre-2010 T1N and early NCV3 Sprinters require a different sensor — part number 0035427118 / Bosch 17019. These sensors are not interchangeable. Always verify your model year and engine code before ordering.
