P2293 on BMW
Fuel Pressure Regulator 2 Performance
P2293 on BMW vehicles indicates fuel pressure regulator 2 performance. Au7o has documented this code across 2 BMW models — most commonly on 3 Series, 5 Series. 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 BMW range from $500 to $1,200, 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 BMW by Model
BMW 3 Series(1 issue)
- High Pressure Fuel Pump (HPFP) Failure2007-2010
The N54 twin-turbo engine's high pressure fuel pump can fail, causing long cranking, rough idle, and power loss. BMW extended warranty coverage and released updated pump designs.
BMW 5 Series(1 issue)
- N54 High Pressure Fuel Pump (HPFP) Failure (Safety Critical)2008-2012
The N54 twin-turbo engine's high pressure fuel pump fails prematurely, causing sudden engine stalling, long cranking, and dangerous power loss while driving. BMW used defective HPFP designs with faulty internal roller tappets that wear out by 50,000-80,000 miles. Pump failure leaves car stranded and creates safety hazard when engine dies on highway. BMW extended warranty coverage to 10 years/120,000 miles after NHTSA complaints exceeded 987 reports. This is THE most common N54 failure. Updated revision pumps (part numbers ending in higher letters like "F" or "G") are more reliable. Affects E60 535i (2008-2010) and F10 535i (2011-2012 early). Bimmerpost ranks HPFP as #1 N54 problem - failure rate near 60% on original pumps.

What does P2293 mean on BMW?▼
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 BMW specifically, this code is documented across 2 models.
What causes P2293 on BMW vehicles?▼
Common causes on BMW: 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.
