Buying Tips for 2009 Renault Megane Mk3

  • Check keyless entry and all door-handle buttons because handle microswitches fail with age
  • Verify the electronic parking brake engages and releases smoothly on repeated cycles
  • On 1.5 dCi cars, solid service history matters more than mileage because turbo, EGR and injector condition follow maintenance quality
  • Listen for interior blower issues and suspension knocks because both are common annoyances
