Engine light on (exhaust system)

[Xavier]

Hello everybody,
I'm from Portugal and I have a Leon FR from 2021, 2.0 TDI, 116 cv.
Currently have 35000 km (21747 miles) and the yellow engine light turned on, I scanned the errors with OBD Eleven device and the failure code it's P013300 - sensor 1, bank 1 - very slow signal.
I'm afraid because the guaranty time already finished and I don't know exactly what is the issue. I think that the problem it's the O2 (Lambda) sensor but not sure, so I ask your help, if someone had that problem could please help?

Many thanks,
Have a great day!

Seat give a three year warranty in Portugal, so you should still be covered?

Engine management light on for me too. I guess because of the excessive oil consumption a year ago from new . it must have had a down stream effect ( egr or dpf) . Off to the garage again. It’s under warranty so here’s expecting seat actually cover it .

In my case, the issue was fixed replacing the lambda sensor, outside the warranty by myself.

Looks like it is a pressure sensor on the glow plug. Output implausible P03AA00
