Desculpem lá tar em ingliu, mas já tinha feito, por isso fica o copy/paste.
So, I have a problem with my O2 sensor. Not sure what it is though.
I have this error on VAGCOM:
16515 - Oxygen (Lambda) Sensor B1 S1: Signal too low
P0131 - 35-00 - -
And checking on AUTODATA, I can find this:
16515
Fault Location
Heated oxygen sensor (HO2S) 1, bank 1, voltage low
Probable cause
Wiring short to earth, HO2S
We went to check the wiring, all connected correctly, (pin on the ECU plug corresponds to the pin on the Lambda plug, so everything is wired correctly).
I get these readings on VAGCOM for the lambda:
What can be wrong here? Where to look?
If the lambda sensor is not the correct one (from another year 1.8T, or something with a different part number), could it be the problem?
Let me know your thoughts.
Thanks!
