Where are the oxygen sensors on an Audi A3?

There are many oxygen sensor related codes. These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are. For instance, an oxygen sensor at bank 1 – sensor 1 would be: Bank 1- Side of the engine with the first cylinder in the firing order.
