Ford Focus Mk2 1.6 TDCi 110bhp — Swirl Flap Motor Failure

Root Cause
The swirl flap actuator motor is an underpowered unit that can burn out after years of constant use. The flaps themselves can also seize in position due to carbon build-up on the spindles.
How To Fix
- Read codes — P2004/P2006 confirm swirl flap position fault
- Try cleaning the flap spindles with carb cleaner before condemning the motor
- Replacement motor: £80-150 (OEM Pierburg unit)
- Alternatively fit blanking plates if flaps are beyond cleaning (£30)
- Full replacement at indie: £200-350
