Sensor 3 flue gas temperature block 1

[GeorgeB2000]

Good evening dear colleagues and Audi owners, on my Audi A6 c7 2014. 3.0 bitdi quattro the yellow engine appeared on the dashboard, and I put obd 11 to see what error I get and I discovered a P242B, I understood that it is an exhaust gas temperature sensor, and I would like if any colleague could tell me where it is located and a code on the part to change it, thank you!

Either way check near the manifold, cat, or other places along the exhaust or even dpf.
