Answers to the questions our specialists get most often. Not sure? Send us the VIN — free 4-hour reply.
The OEM part number is the only reliable answer. Find it in your vehicle service manual, on the part itself, or by decoding your VIN. Search that number in our catalogue — if it appears on a listing, that part fits. If it does not appear, contact us and we will cross-reference it against the Bosch / Denso / VDO database for free.
The manufacturer's own identifier for a part — Bosch 5WK96667C, Mercedes 0009053403, Cummins 4962852, VDO 4551030096. Different manufacturers use different formats, but the number uniquely identifies the specification. Product names are not — two parts can share a name and not fit the same engine.
Our catalogue is a mix. Where a listing is a direct OEM replacement, the listing shows the OEM number and the word "OEM". Where it is an aftermarket part cross-referenced to an OEM number, we say "Cross-reference" and name the manufacturer. We do not sell counterfeit parts and we never misrepresent a part's origin.
Some NOx and DEF sensors require ECU coding after installation, especially on Mercedes-Benz, VW Group and Cummins platforms. If the listing requires coding, it is marked. Ask us before ordering if you are not sure whether your vehicle's ECU will accept a non-genuine sensor without a DTC.
