Diagnostics on Porsche
Called out to a fellow local garage to assist with a faulty porsche that kept on throwing cam and crank correlation codes out. The main dealer had failed to diagnose the fault we scoped the cam and crank signals and found this. Red signal is camshaft bank 1 and blue signal is camshaft bank 2, green is crankshaft signal. The Blue signal was 11 degrees retarded so timing needs attention.
