Book a DiagnosticCall (423) 702-9900

Turbocharged MINIs use a high-pressure fuel pump that can fail over time, causing long cranks, stalling, and reduced power. At Inline Autohaus in Chattanooga, we diagnose and replace failing MINI fuel pumps to restore reliable starting and performance.

Symptoms We See

  • Long cranking before starting
  • Stalling or rough running
  • Reduced power or hesitation
  • Check-engine light with fuel-pressure codes
Affected models:
MINI Cooper S, JCW (N14, N18 turbo)

Why It Happens

The high-pressure pump feeds the direct-injection system, and internal wear causes it to lose pressure. As pressure drops, starting and running suffer. Replacing the pump restores correct fuel delivery.

How We Fix It

  1. Fuel-pressure testing and scan to confirm the pump
  2. Inspection of fuel delivery
  3. Replacement of the high-pressure fuel pump with a quality part
  4. Re-test to confirm reliable starting
Parts we use:
