Changing Lambda sensor

Running too rich.

Running too rich.

Sure. But chicken and egg. Too rich because the G62 failed (where did we just hear that) OR the O2 sensor died and the ECU didn't have the correct feed back?

No codes in this story?

No codes in this story?

Like:

2342 (Blink Fault Code), 00525 VAG1551/2 Fault Code Number
Oxygen Sensor (G39)
Sensor Wiring or Sensor defective Heat resistor in sensor defective, Signal wiring shorted to ground, Fuel tank empty, Ignition system component failure, air leak at mass air flow sensor, air leak in exhaust pipe before catalyst, poor ECU ground wire connection at intake manifold.
Symptom: Emissions not within specifications, increased fuel consumption, rich exhaust, spark plug fouling,
Carbon Monoxide (CO) percentage above 3%

Or Another indirect O2 issue code is:

2341 (Blink Fault Code), 00537 VAG1551/2 Fault Code Number
Oxygen Sensor Control Limit exceeded,
fuel pressure too low or too high, intake or exhaust leak, defective ignition system component, intake air leak after air mass sensor, O2 sensor is faulty (Like having a bunch of burnt oil on the tip)

David, the only fault code i've had for the past few months is 00561 : Max/Min adaptation not reached. I'll have to wait and see if it returns.

The car seems much smoother now. Gear change is smoother, and the engine doesn't bog down as much when moving off in 1st gear... Not the side-effect i was expecting.
