3.0tdi please help..!!!

Hi All

Just need some clarification on EGT sensors for a 3.0tdi CDUC engine.

Vag reads the following when engine cold.

Sensor 1 - 32c
Sensor 2 - 222c
Sensor 3 - 31c
Sensor 4 - 32c

Sensor voltage 1 - 930mv
Sensor voltage 2 - 0mv
Sensor voltage 3 - 930mv
Sensor voltage 4 - 930mv

So this would dictate that I have a problem with sensor 2 only problem is where is it ?.

Sensor 1 Pre Turbo
Sensor 2 ?
Sensor 3 pre Cat Dpf
Sensor 4 post Cat Dpf

I tried the Egr temp sensor but didn’t change anything on vag but did give an error code when disconnected.

Is sensor 2 just a vacant slot so to speak ?.

Any help would be great
Thanks
