Location of 02 sensor B1 S2

I own a 2011 TDI which has thrown a P0136-003 code. It says it is a B1 S2, which I think is Bank1 Sensor 2. Where is this sensor located physically? Thanks A link to a picture would sure be nice or You Tube

It is the Lambda sensor in the exhaust pipe under the car, the only one down there. In the pipe directly ahead of the exhaust control flap. The #1 lambda sensor is up in the DPF/cat assembly near the firewall.

If you are using a generic scan tool, though, you may not be getting the correct information anyway.

Thanks oilhammer for the location. I will see if I can find it. I scanned it with my Ross-Tech VAG/VAS, so it should be the 2nd sensor. I will remove it and test it. Thanks, Terry
Ps. Sorry guys about posting this in the wrong area.

If you are using VCDS, you're golden. No problem then.

If I had one in the shop I'd take a picture. But it isn't really hidden or anything. It is angled up, so it sort of is up in the tunnel area.
