After having my last S3 for 6 odd years I had a break but recently got the itch to spend money and time fixing old cars so bought another one! Tis a lovely pre facelift example in really good condition. Overall it drives really well...
However! I've put my bluetooth obd2 thing in with torque app and found it's only boosting to 9psi and maf reading of 130g - 160bhp - there's no codes with vcds and vac shows -22 on idle so I'm assuming no leaks, I can't find any anyway. So my question is where to start, might well be a tired maf giving low figures but would that fix the low boost or should I look at the low boost first and see if that cures the low maf figures?! Where would you start?
It's good to be back apart from that
