Buying Tips for the 2018 Ford Focus Mk4 (C519)
- ✓EcoBlue diesels should only be bought after a fully warm drive with no AdBlue, NOx or repeated regeneration warnings lurking in the dash or fault memory.
- ✓Check the SYNC system and 12V battery behaviour carefully because battery-drain complaints and module wake-up issues can make these cars seem randomly unreliable.
- ✓Scan the car if possible, because active grille-shutter and other body-module faults do not always announce themselves with a clear dashboard message.
