P2293 on Audi
Fuel Pressure Regulator 2 Performance
P2293 on Audi vehicles indicates fuel pressure regulator 2 performance. Au7o has documented this code across 1 Audi model — most commonly on A4. This code means the engine computer has detected that the fuel pressure regulator 2 isn't performing as expected, so the system can't maintain the correct fuel pressure under varying conditions. On many direct-injection and high-pressure systems, regulator 2 controls the high-side fuel pressure, and the computer compares commanded pressure to what the fuel pressure sensor actually reports. When the measured pressure drifts too far from the target, it sets this performance code, which can cause hard starting, rough running, hesitation, reduced power, or stalling. Causes typically include a faulty regulator or high-pressure pump, a fuel delivery restriction, or a pressure sensor problem.
Common Causes of P2293
- •Faulty fuel pressure regulator (regulator 2)
- •Failing high-pressure fuel pump
- •Faulty or out-of-range fuel rail pressure sensor
- •Clogged fuel filter or restricted fuel supply
- •Weak low-pressure (lift) pump feeding the high-pressure system
- •Leaking fuel injector bleeding off pressure
- •Wiring or connector fault to the regulator/pump
- •Air or contamination in the fuel system
P2293 on Audi by Model
Audi A4(1 issue)
- 2005-2007 A4 2.0TFSI Cam-Follower / HPFP Diagnosis - TSB 2013147/122005-2007
Audi TSB 2013147/12 applies to 2005-2006 A4 vehicles with the BPG engine and 2007 A4 vehicles with the BWT engine when the MIL is on and P2293 is stored; P0087 or P1093 may accompany it. Audi’s procedure checks fuel pressure and wear at the cam follower, intake camshaft lobe and high-pressure fuel pump. The documents do not publish a universal inspection interval and state the covered condition does not cause stalling.

What does P2293 mean on Audi?▼
P2293 stands for "Fuel Pressure Regulator 2 Performance." This code means the engine computer has detected that the fuel pressure regulator 2 isn't performing as expected, so the system can't maintain the correct fuel pressure under varying conditions. On many direct-injection and high-pressure systems, regulator 2 controls the high-side fuel pressure, and the computer compares commanded pressure to what the fuel pressure sensor actually reports. When the measured pressure drifts too far from the target, it sets this performance code, which can cause hard starting, rough running, hesitation, reduced power, or stalling. Causes typically include a faulty regulator or high-pressure pump, a fuel delivery restriction, or a pressure sensor problem. On Audi specifically, this code is documented across 1 model.
What causes P2293 on Audi vehicles?▼
Common causes on Audi: Faulty fuel pressure regulator (regulator 2), Failing high-pressure fuel pump, Faulty or out-of-range fuel rail pressure sensor, Clogged fuel filter or restricted fuel supply, Weak low-pressure (lift) pump feeding the high-pressure system. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2293 on a Audi?▼
Repair costs vary widely depending on the root cause and specific Audi model.
Which Audi models have P2293 documented?▼
