Lambda Sensor-Emissions Control System warning light
 

Hi

I have an Audi A3 1.6 may 2003 (newer model).
Changed my ABS control unit,now i have a Emissions Control System warning light,garage ran diagnostics,showing fault of intermittent front probe,cleared fault,came back same day,still on now.Told i need to change Front Lambda Sensor,have been trying to source the part second hand,but having problems trying to find the 5 WIRE-with the BLUE wire not the RED.
Dont know why it is so hard to get,everywhere i tried have the red wire?

Would any body have the part number please.

Kind Regards

Are you certain that it has to have 5 wires? It seems the majority refer to the 4 wire plug.

Anyhow this website seems to list both 4 and 5 wire ones:
