NOx sensor wiring - for retrofitting Golf sensor

[VETRA]

Hello everybody!

I have a permanent error on the NOx sensor (Signal too low) on my 2001 A2 1.6 FSI. So, I am looking to replace it.

The original NOx sensor (8Z0 906 261) is >400Eur if I am lucky to find one available in stock...

VW Golfs of 2003-2008 had the same (BAD) engine and their NOx sensors (036 906 261 D) look very similar - except for a shorter cable and a different plug.

Our sensor:

Golf's:

 

The connectors look the same, so i would guess the pinout is the same - but this is just a guess...

 

So I am thinking to take out my NOx sensor, cut the wires and solder in the sensor from Golf.

The issue is  - I am struggling to get the pinout of the Golf's sensor.

VW Golf (BAD) diagram:

The exact pin-by-pin assignment of the G295 sensing element on VW GOLF 2003 – 1.6 l/81 kW, engine code BAD is not published in VW service literature, because on the BAD 1.6 FSI system the G295 NOx sensor and J583 NOx control unit are treated as one assembly. The service wiring diagrams only show the vehicle-side connector T10v (10-pin) at the J583 control module, not the internal sensor wiring.

 

Has anybody here done this already? Do you know the Golf's NOx sensor G295 pins assignment? Is it identical to ours?

Thanks alot!!

Give it a try, the internal wiring will be most likely the same because its a Carry-Over-Part used in many vag Cars. I would pin it according to the cable colours.
