2018 Q5 EPC Light and Misfire Codes (P0301, P2293)

Hey everyone, I'm having a major issue with my 2018 Audi Q5 2.0T Premium Plus. The EPC light came on yesterday, and the car immediately went into limp mode. It's running really rough, almost like it's misfiring badly.

I managed to get it home and scanned it with my OBD-II tool. I'm getting codes P0301 (Cylinder 1 Misfire Detected), P0300 (Random/Multiple Cylinder Misfire Detected), and P2293 (Fuel Pressure Regulator 2 Performance).

Has anyone experienced this combination of issues? Could it be a bad fuel pump, or something else entirely? Any advice on where to start troubleshooting would be greatly appreciated before I take it to the dealer.

ClearTheCode guidance (Audi · Diagnostics & codes)

Summary: For 2018 Q5 EPC Light and Misfire Codes (P0301, P2293), work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
