Throttle Bodies error

[saint70]

I had engine light on dash board other day and decided to use OBD2 tools for inspecting error.
Comes up with "P0121 Throttle/pedal position sensor/switch a circuit range/performace problem".
One note: I have passat B7 tdi and i am not sure if passat has Throttle Bodie at all
Car drives well and no problem with accelaration or any issue.
I wonder if someone can help me why engine light comes up...
i forgot to mention, all issues started since software update done (

In case someone wants to know what happened....
Throttle body gone. Replaced with brand new one. Car drives very smooth, no rough shutdown feels.
Cost including installation: 800$
