I was driving along today and the engine light comes on.
When i got home i did a scan and this was the only fault:
16522 - Oxygen (Lambda) Sensor B1 S2: Signal too High
P0138 - 35-00 - -
Readiness: 0000 1000
I've seen generic codes say Sensor 1 for the pre cat and sensor 2 for the post cat, And I've seen vagcom show bank 1 for the pre cat and bank 2 for the post cat.
Can someone tell me what sensor Bank 1 Sensor 2 (B1 S2) is ?
