Do I need 2 or 4 O2 sensors?
I have a 2.8 30V and I was wondering if the codes that I pulled require me to change ll four or just two of the O2 sensors. I am asuming that since I have a 2.8 there are 4 O2 sensor, but please correct me if I am wrong. The codes where P1198 and P1199. Thanks

1.8T = 2 sensors, 2.8 = 4 sensors (locations inside)
VAG the car and it will give you the location of the failed sensor:
1.8T
B1S1 = sensor in FRONT of the cat
B1S2 = sensor BEHIND the cat
2.8
B1S1 = sensor in FRONT of passenger side cat
B1S2 = sensor BEHIND passenger side cat
B2S1 = sensor in FRONT of driver's side cat
B2S2 = sensor BEHIND driver's side cat
Cheers,
1.8T
B1S1 = sensor in FRONT of the cat
B1S2 = sensor BEHIND the cat
2.8
B1S1 = sensor in FRONT of passenger side cat
B1S2 = sensor BEHIND passenger side cat
B2S1 = sensor in FRONT of driver's side cat
B2S2 = sensor BEHIND driver's side cat
