Cruising about 180 miles round trip last Tuesday (all freeway 70-90mph) and my EPC light came on. Once it was on, noticed the car still had power but wouldn’t pull above 4k rpm. Got home, shut it off, started driving again, EPC light was now off, but the engine light is on solid. Pulled the codes with my standard scanner and had Audi/VW specific codes
P129B- Fuel Pressure regulator
P1077- 02 sensor too lean bank 4
P1075- 02 sensor too lean bank 3
Assuming possible HPFP might be on its way out… i’ll pull vagcom codes later
thoughts?
