Have a 2016 Audi A3 1.6 TDI CXX engine code. The car is making a loud pinking noise, earlier on it drove fine started jerking slightly around 2k rpm, when revving was making a loud pinking/knocking noise (very noisy injector sound). The car idles perfectly smooth, just went outside to move it and I now have a flashing glow plug light and the pinking/injector noise is constant (very loud). I have an error code P019200 (Fuel rail pressor sensor A circuit low input). Anyone have any ideas. Car has done 78k so hasn't done huge miles at all.
