    Hi folks, my wife’s A3 1.8tfsi 2008 ,58 reg has a fault with it, it’s bringing on the light with code P0171 system to lean, I checked for vacuum leaks in hoses but can’t see anything , it seems to be using more fuel and exhaust tips are black which would make sense if it’s running rich , it has a very very small misfire on idle but so small it’s hardly noticeable . I clear the code and it comes back on about a week to 2 weeks later . My small code reader has freeze frame and live data on it so I have posted the freeze frame pictures below , I don’t know what I am looking for so can someone please be s savour and help me
