My Audi was stalling every time I stopped. Now it’s sitting in the driveway can’t stay running for more than 5 seconds. I changed all 4 injectors, coils, plugs, hpfp, and pcv valve. it cranks and has spark but won’t stay running. I got codes p0506 p2188 02178 p2279 before I replaced everything.
I don’t know what else to do I need any help you have

 

I don't know if you every solved this, but the codes point to a fuel issue on bank 1. I googled all the codes and wonder if your Mass Air Flow (MAF) is plugged or failed? Either that or it sounds like a fuel rail issue (part of the fuel injection) which is way outside my scope of knowledge.

 

low compression. Just finished rebuilding the motor dropping it in this weekend
