I have a 2008 Sprinter with a V6 3L diesel engine that is where I fitted that. The C280 is a gas engine no? I had the older 2002 Sprinter that had the 2.7L inline 5 that is a different engine with different exhaust system.

Hi Glenn, An air–fuel ratio (AFR) monitors the internal combustion engine and is the same as the oxygen sensor. My question is, do you need the Upstream (before the catalytic) or the downstream (after the catalytic)? This part is for the Downstream (After Catalytic Converter Or Center) compatible with the 2006 Mercedes Benz C280 4Matic 6 Cyl 3.0L Engine Designation: 272.941, FI, Naturally Aspirated, GAS. NOTE: This part is NOT for the Luxury Submodel.
