P0191 on MINI by model: symptoms, diagnosis and fix
The N14 engine's high-pressure fuel pump (same issue as early BMW N54) fails prematurely, causing long cranking, rough running, and stalling. The internal cam follower wears down, reducing fuel pressure to the direct injection system.
Common Symptoms
- Long crank time
- Rough idle
- Stalling
- Loss of power under acceleration
- Fuel pressure fault codes
How to Fix
Replace HPFP and inspect cam follower for wear. Updated HPFP has revised internals. Check fuel pressure with scan tool - should be 50+ bar at idle, 100+ bar under load.

The N14 engine's high-pressure fuel pump (HPFP) is an extremely common failure point, with failures documented as early as 40,000 miles. The HPFP fails to maintain adequate fuel rail pressure, causing hard starting, extended cranking, stalling, and reduced engine power. MINI issued a service bulletin acknowledging the premature failure. If not addressed, low fuel pressure under boost can cause lean combustion conditions that damage pistons and valves.
Common Symptoms
- Extended cranking or multiple attempts needed to start engine
- Engine stalling at idle or during low-speed driving
- Reduced engine power warning on dashboard
- Rough running or misfires under boost
- Check engine light with fuel pressure-related codes
How to Fix
Replace the HPFP with the updated design part — MINI revised the pump internals to improve durability. The replacement costs $400-800 for the pump plus $200-400 for labor. When replacing the HPFP, also replace the low-pressure fuel pump relay and inspect the fuel pressure sensor. An aftermarket upgraded HPFP from Autotech or similar can handle the increased fuel demands of a modified JCW.

Owner tips & cautions
- TipIf your JCW cranks for more than 3-4 seconds before starting, get the HPFP tested immediately. Driving with a failing pump risks lean-condition damage to the engine under boost that is far more expensive to repair.
The direct-injection engines in the Paceman use a high-pressure fuel pump that can fail without warning. HPFP failure causes immediate stalling or inability to start. The issue is related to internal cam follower wear and is shared with other MINI/BMW turbocharged engines.
Common Symptoms
- Engine stalls suddenly
- Long crank with no start
- Check engine light with fuel pressure codes
- Reduced power under load
- Stuttering during acceleration
- Fuel smell from engine bay
How to Fix
Replace the high-pressure fuel pump and inspect the cam follower for wear. The cam follower should be inspected every 50,000 miles and replaced preventively if worn past the service limit.

MINI GP models with turbo direct-injection engines have documented HPFP failures that can cause long crank/no-start, limp mode, and reduced power. The pump can lose pressure internally or fail electrically, often showing up under hot restarts or heavy load. Owner reports and NHTSA complaints across R56/R60-era MINIs (including GP2’s N18) frequently describe intermittent stalling and repeated fuel-pressure faults.
Common Symptoms
- Long crank or no-start (especially hot)
- Sudden loss of power/limp mode under boost
- Engine stalls at idle or when coming to a stop
- Rough running/misfires with fuel pressure faults
- Check Engine Light with fuel rail pressure codes
How to Fix
Replace the high-pressure fuel pump and perform fuel system adaptations/coding as required. Common MINI/BMW HPFP part numbers vary by engine and production date (verify by VIN), including BMW/MINI 13 51 7 616 446 and related supersessions; replace the HPFP mounting bolts and inspect the low-pressure supply and fuel filter/regulator where applicable.

Frequently asked questions
What does P0191 mean on a MINI?
P0191 stands for "Fuel Rail Pressure Sensor Circuit Range/Performance." This code sets when the fuel rail pressure sensor's signal is out of its expected range or doesn't match what the computer expects for current conditions. On direct-injection and many modern engines, this sensor reports fuel pressure in the rail so the computer can precisely control fueling and the fuel pump. When the reading is implausible — too steady, erratic, or inconsistent with commanded pressure — this code is set, sometimes with hard starting, hesitation, or reduced power. It generally points to the sensor or its wiring, though an actual fuel-pressure problem can also trigger it. On MINI it is documented across 4 models: Cooper S, John Cooper Works, Paceman, GP.
What are the most common causes of P0191?
The most common causes of P0191 are: Faulty fuel rail pressure sensor, Corroded, loose, or damaged sensor connector, Open, shorted, or high-resistance sensor wiring, Actual fuel pressure out of range (weak pump or regulator), Restricted fuel filter or supply line, Loss of reference voltage or ground from the ECM/PCM, Faulty fuel pressure regulator or control valve. The specific cause varies by vehicle.
How much does it cost to fix P0191 on a MINI?
Published repair estimates on MINI range from $500 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.
