Hello,
I have a question regarding the second O2 sensor on the cat. In my facelift EK9 from november 98' I see a second O2 sensor on the cat. This sensor is not connected an I have no DTC. But I have some trouble with the CO test. eventually I pass but with a lot of effort.
After some research I learned that the OBD2 EK's (facelift) have x2 O2 sensors on the cat. the primary is connected via the engine harness and the secondary is connected with the cabin harness. But when I look under the car I can't seem to find the hole + connector. Also when I disassemble the central console in the car I cant find any loose cable or connector above the tunnel.
My question is do facelift EK9's have a secondary O2 sensor?
