Audi TT mk2 3.2L upstream O2 sensor replacement (Easy)

Found a way to access the upstream O2 sensor without having to remove the intake manifold and exhaust cover. A little tight but doable.

I've got a Bank 2 Sensor 1. On a UK car (RHD) is the convention the same, or is it the other way round?

[@TAG-theasiangarage]

@@The_Voice_of_Reason748 I believe it would be the same

[@alexizaguirre7961]

Can you link where you bought them? I cant seem to find anywhere that has them.

[@adrianfry8059]

Do you have to have the codes reset once the new one is installed, or will the engine light disappear if the fault was actually with the sensor? Thank you

[@TAG-theasiangarage]

It should reset itself after a while, but it doesn’t hurt to reset it with an obd.

I have audi same 3.2 got code p0156 do u know which sensor that is bank 2 downstream ?

[@TAG-theasiangarage]

Yes. A simple Google search would show that too I believe.

Did it sort your engine light out? I have a 2.0 model and the after cat one needs changing according to obd
