I got my a3 as a project at first I had over 30 faults but that was due to a dying battery shut down most of the electrics..and a running fault due to cam sensor.
I've got its running a lot better service the engine and so on
now I'm down to two fault which I'm unsure if there's a undying fault bring up both fault please see pic below my car running lean, first fault feel pressure sensor and number down to nox sensor at first I thought the nox sensor needs replacing but the code relates to bank 1 not back 2...on the exhaust manifold there a small egr take off with black suit both side...next thing I could think of doing is fuel filter (maybe blocked) and replace the Lil gasket on the manifold for egr. ...could the hpfp be at fault...I'll add the car runs fine but there a very slight miss fire on tick over...I don't claim to be a know it all I'm just handy with a spanner it's bugging me big time it's a lovely car I'm just afraid if I drive it ill damage it....tia for any help on my issue
