Hey guys, on my v6 BWS engine Passat CC (MY12), I'm getting engine warning light. Car is approx 100,000km old. Plugged in VCDS & got following:
8218 - Post-Catalyst Oxygen (Lambda) Sensor Correction; Bank 2
P2098 00 [237] - Too Lean
MIL ON - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 1
Mileage: 101826 km
Date: 2085.14.28
Time: 14:01:42
Engine speed: 2213.50 /min
Normed load value: 43.1 %
Vehicle speed: 110 km/h
Coolant temperature: 96 °C
Intake air temperature: 39 °C
Ambient air pressure: 1000 mbar
Voltage terminal 30: 13.099 V
Unlearning counter according OBD: 40
Oxygen sensor bank 2 sensor 1: specified value: 1.0000
Oxy sensor 1 bank 2 char curve offset: -0.03503
Oxygen sensor 1 bank 1 fast offset adaptation counter: 255
Oxy sensor 1 bank 2 offset spec value: -0.00211
Test of oxygen sensors bank 2: Delta-Lambda: -0.00003
2947 - Oxygen (Lambda) Sensor Signal B2 S2
P2272 00 [096] - too Lean
Intermittent - Not Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 3
Mileage: 100435 km
Date: 2085.14.09
Time: 18:34:01
Engine speed: 2226.50 /min
Normed load value: 49.8 %
Vehicle speed: 111 km/h
Coolant temperature: 95 °C
Intake air temperature: 37 °C
Ambient air pressure: 1010 mbar
Voltage terminal 30: 14.135 V
Unlearning counter according OBD: 33
Rear cat conv temp main cat conv model value: 601.73 °C
4120 - Oxygen (Lambda) Sensor B2 S1
P2198 00 [237] - Signal too High (Rich)
MIL ON - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 1
Mileage: 102005 km
Date: 2085.14.28
Time: 15:52:41
Engine speed: 2194.00 /min
Normed load value: 32.9 %
Vehicle speed: 109 km/h
Coolant temperature: 95 °C
Intake air temperature: 42 °C
Ambient air pressure: 1000 mbar
Voltage terminal 30: 13.122 V
Unlearning counter according OBD: 40
Oxygen sensor bank 2 sensor 1: specified value: 1.0000
Oxy sensor 1 bank 2 char curve offset: -0.05902
Oxygen sensor 1 bank 1 fast offset adaptation counter: 238
Oxy sensor 1 bank 2 offset spec value: -0.00204
Test of oxygen sensors bank 2: Delta-Lambda: 0.0000
I had another "Too Lean" error 8218 a couple months ago that I cleared.
Is this a sensor fault, a Cat issue or something else? I wouldn't expect a O2 sensor to fail at only 100,000km (but I do have a long Japanese car history)
