Location of Exhaust Gas Temperature Sensor No3

[YellowVrsToo]

EGT Sensor #3 has failed on my 2010 Octavia II VRS Diesel. VCDS reports "Exhaust Gas Temperature Sensor; B1 S3 P242A - 000 - Malfunction" and I get the flashing coil and "Engine fault- Workshop". Despite lots of searching (including BriSkoda) I'm having trouble finding out where it is. Can someone help, please?

Er - thanks AMD87 but it's a diesel.

Probably item 15 here: https://skoda.7zap.com/en/cz/octavia/oct/2010-663/9/906-906015/

As opposed to items 10 or 12, which logic suggests would be temperature sensors 2 and 1 respectively?

I would expect AMD to know what he's on about though, and if you look at this diagram, it does refer to a cat in the title: https://skoda.7zap.com/en/cz/octavia/oct/2010-663/2/253-253063/

 

Hope I'm picking the right engine code diagrams for your car.

Sorry must have misunderstood, my bad.

Thanks for your help guys. Found it - almost, but not quite, inaccessible - on the front of the DPF (?) behind the oil filler tube. Changed it and no more flashing coil! Engine fault light still on, but I guess that will go away in time. If not I'll get the VCDS out again!
