What to check on a 2018 Citroen C4 Cactus before buying
The three areas where failed first tests most often had a fault, 2023–2025.
- Lamps and electrics. Ask someone to watch while you work the brake lights, indicators, sidelights, dipped and main beam, and the number-plate lamps.
- Wipers and windscreen. Worth checking that the wipers clear the screen cleanly, that the washers work, and that there are no chips or cracks in the driver’s view.
- Tyres. Worth checking the tread depth across the whole width of each tyre, and the sidewalls for cuts, cracks and bulges.
