Sensor 1 is dead. Sensor 2 is good.

Check new log. I replaced pre-cat sensor.

Lambda 1 does not work well. There should be a beautiful sinusoid from 0.05 to 0.9 volts, here is a mess.

It is log from VCDS and it refresh data with little late. Don't know. I put new NGK lambda. It wasn't cheap.

Ill give it a shot
1 What engine?2.0?what year?
2 Stock ecu or tuned?
3 Any fault codes?
4 How much oil does it burn?

Let not cheap, but not working as it should.
Maybe the measurements were cold and it has not warmed up yet?
If it’s hot, then the sensor is bad.

1.6 16V
ECU with EGR off
No fault codes
Does not burn oil. Compression is very good.

1.6 16v what engine code?
What year?
LAmbda sometimes reads wrong because airflow or map is not working well.Injectors clocked and stuff like this.
