P2293 on Audi
Fuel Pressure Regulator 2 Performance
P2293 on Audi vehicles indicates fuel pressure regulator 2 performance. Au7o has documented this code across 3 Audi models — most commonly on A4, S7, TT. 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. Typical repair costs on Audi range from $150 to $6,000, depending on the specific model and root cause.
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 The documents do not publish a universal inspection interval and state the covered condition does not cause stalling.
Audi S7(1 issue)
- High-Pressure Fuel Pump (HPFP) Failure Causing Hard Start and Power Loss (4.0T V8)2013-2018
The 4.0T TFSI V8 in the S7 uses two cam-driven high-pressure fuel pumps (one per bank). A failing HPFP cannot maintain rail pressure, producing long cranking, no-start (especially when warm or cold), stalling, rough idle, and reduced power, typically with low fuel-rail pressure codes. German S7 owners report the Hochdruckpumpe as a replacement item alongside the PCV/oil separator. The cam follower that rides the pump tappet should always be replaced with the pump to avoid damaging the new pump and camshaft.
Audi TT(1 issue)
- Cam Follower Wear (Damages Camshaft and HPFP)2008-2014
The 2.0 TFSI engine in the Mk2 TT (2008-2015, particularly 2008-2009 base and 2009-2014 TTS) uses a cam follower (bucket tappet) that rides on the camshaft to drive the high-pressure fuel pump (HPFP). This follower is a wear item that can get completely ground down over time, typically by 60,000-100,000 miles. When the follower wears through, it damages the camshaft lobe and HPFP, causing catastrophic engine damage requiring camshaft replacement ($2,000-$3,000), HPFP replacement ($800-$1,500), and potentially complete cylinder head rebuild ($4,000-$6,000). Symptoms include loss of power, rough running, metallic ticking, and fuel pressure faults. This is a KNOWN DEFECT requiring preventive inspection and replacement.

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 3 models.
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 on Audi range from $150 to $6,000, depending on the specific model and root cause.
