S3 8L Lambda erorrs - Newbee Q's

Hi all

I have had the EML come on and does so after 5  or so startups, and it will clear but obviuosly comes back.

The basic error codes are slightly different but basically  Oxygen (Lambda) Sensor specific.

16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit P0130
17861 - Exhaust Gas Temp Sensor 1 (G235): Open or Short to Plus P1453
17510 - Oxygen (Lambda) Sensor Heating: B1 S1: Short to Plus P1102

can anyone advise what part I need change, and if that's the actual issue. I was told the car had recently had a O2 sensor, but new to S3's

I can see the lambda probe on the exhaust behind the cats, but wasn't sure if 1. there is another sensor, and 2. which sensor the errors relate.

many thanks
