I've fixed quite a few Audi P1093 faults, which is a Fuel System 2 issue, usually indicating a fuel supply problem in the right bank of cylinders. Common causes include insufficient fuel pump pressure, clogged fuel injectors, or aging oxygen sensors leading to a mixture that's too lean or too rich. While driving, you might notice sluggish acceleration, rough idling, or even a sudden spike in fuel consumption. I must warn you: don't ignore it, as prolonged neglect could damage the catalytic converter or the engine. My advice is to first check the fuel pressure—if it's low, replace the pump; dirty injectors can be cleaned with professional cleaner; and if the sensor is faulty, replace it. Prompt repairs can save you a lot of money and ensure driving safety.
