P2293 on Audi by model: symptoms, diagnosis and fix
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. Audi publishes no inspection interval and states that this condition does not cause stalling.
Common Symptoms
- Check engine light on with code P2293
- Codes P0087 or P1093 may also be stored
How to Fix
Verify BPG or BWT engine fitment, record the MIL faults and measured fuel-pressure behavior, then follow TSB 2013147/12. Inspect the cam follower and cam lobe and replace only the follower, camshaft and/or high-pressure fuel pump selected by the bulletin’s conditional tree. The 10-year/120,000-mile extension is historical and generally expired, so coverage is not guaranteed; do not buy a parts kit before diagnosis.
Sources for this issue (2)
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, stalling, rough idle, and reduced power, typically with low fuel-rail pressure codes.
Common Symptoms
- Long cranking before start
- No-start condition
- Stalling
- Power loss / limp mode
- Rough idle
- Check engine light
How to Fix
Diagnose with live fuel-rail pressure data before condemning the pump, as a faulty low-pressure sensor or in-tank pump can set the same codes. Verify low-pressure (in-tank) supply is within spec.

Frequently asked questions
What does P2293 mean on a 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 it is documented across 2 models: A4, S7.
What are the most common causes of P2293?
The most common causes of P2293 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P2293 on a Audi?
Published repair estimates on Audi range from $700 to $2,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
