A3 1997 Flatspot Intermittent

[any_mgzt]

I have an annoying problem with an intermittent flat spot on my 1.8 1997 A3. Hooked it up to VAG COM and it showed several faults as below:-

Cleared all faults from the ECU and drove the car for a while, checked again and the O2 fault came back, so my question IS where is the O2 sensor I cannot find it?

I have a copy of the VAG COM interface and it runs well with the original VAG COM software £10 in total form EBAY.
