Hello everyone , A3 8P 2.0 TFSI BWA owner here
I've been having issues with my car sputtering , revs dropping , loss of power. The issue stems from loss of fuel pressure OR electrical fault, I'm not sure. Car almost never gives a check engine light or stores any codes but sometimes it does. It gives me P0192 Fuel Rail Pressure Sensor "A" Circuit Low Input (G247). This happens perhaps once or twice a week. Other than that car runs and pulls nicely. I have changed the Fuel Rail pressure sensor and i have taken the car to an electrician to replace all the wiring for the sensor. Made no difference. I have checked all fuses and relays and also the fuel pump control module. On it i saw its from 2018 so its been replaced recently and I figure should be ok. The pump itself is from 2006 so maybe that's the problem? What I really want to know is if the code which I'm getting is a result of electrical issue from the sensor to the ECU or is it a problem with the fuel system? What do you suggest i do next? I was told to perhaps take the ECU to be opened up by a specialist to check for corrosion?

Managed to catch the pressure drop (car didn't throw a code this time)

For anyone interested I'm gonna replace the in tank fuel pump and report back

So I replaced the pump , that wasn't the problem , ended up removing the intake manifold and saw that the previous electrician didn't replace the wires properly. Just cut off the old one , stripped the wire and twisted them by hand.... I soldered the wire properly and I haven't had the problem since. Cant trust anyone these days
