A2: Yes.

  • 04L907807CF = OEM VW Group part number
  • 5WK96737 = Continental aftermarket reference
    They refer to the same NOx sensor used in MQB diesel SCR systems.

A3: It is installed in the exhaust aftertreatment system, usually after the DPF or SCR catalyst depending on configuration (upstream or downstream NOx sensor).

Q4: Which engines use this sensor?

A4: Mainly VW Group 1.6 TDI and 2.0 TDI Euro 6 engines across MQB platforms (Golf MK7, Passat B8, A3 8V, etc.).
