GDI Injector Circuit Malfunction - Cylinder Specific

on 2007 Mini Cooper 1.6L I4 · FWD

What this code means

A GDI fuel injector has an electrical circuit fault. GDI injectors require high-voltage driver circuits for precise fuel delivery at extremely high pressures.

Symptoms

  • Check Engine Light
  • Misfire on affected cylinder
  • Rough idle
  • Loss of power
  • Exhaust smell
  • Catalyst damage risk

Common causes

  • Injector coil failure
  • Injector driver circuit fault in PCM
  • Wiring damage to injector
  • Connector pin corrosion
  • Injector stuck open or closed

Diagnostic steps

  1. Identify affected cylinder from freeze frame
  2. Test injector resistance
  3. Check injector driver waveform with oscilloscope
  4. Inspect injector connector
  5. Swap injectors between cylinders to confirm

Repair notes

Replace faulty GDI injector. Use OEM injectors - aftermarket injectors may not meet flow and spray specifications. Perform injector coding if required.
