Hi guys just scanned my s3 for fault codes and I've had 11 faults come up and they are as follows

17937 - camshaft timing adjustment: short to plus
             P1529 intermittent

17705 (p1297)

17608 (p1200)

16487- mass air flow sensor (g70) signal too high
           P0103 intermittent

17704 (p1296)

16684 (p0300)

16685 - cylinder 1 misfire detected
             P0301

16688 (P0304)

17863- exhaust gas temp sensor 1 (g235) implausible signal
            P1455 intermittent

I've just picked up a turbo for it as the current one is at the end of it's working life (making a loud humming noise) any help on these though?

Cheers lee
