Buying a used Citroën C4 requires special attention to… technical items and maintenance signsTo avoid unexpected expenses and future problems, this checklist serves as a complete guide for evaluating a car before purchase.

7.1 Exterior and Bodywork

• Bodywork: Look for differences in tone or ripples, which may indicate dents or repainting.
• Doors and hood: Open and close to check alignment and clearances.
• Visual suspension: Check if the car is level; a car that is lower on one side may indicate suspension problems.
• Tires: Check for uneven wear, which may indicate misalignment or loose suspension.

7.2 Engine and Compartment

• Engine oil: Check the color (light yellow is normal; dark brown indicates a need for replacement).
• Leaks: Check for oil, brake fluid, and water in the engine compartment.
• Timing belt: Ask the seller when it was last replaced; it shouldn’t be worn or cracked.
• Battery: Check the validity and condition of the terminals.

7.3 Brake and Suspension System

• Brakes: Test the pedal to make it firm; noises or a low pedal feel indicate worn pads or old fluid.
• Suspension: Test the tires on speed bumps; sharp noises may indicate worn shock absorbers or bushings.
• Alignment: Check if the steering wheel is centered; if it pulls to one side, it indicates misalignment.

7.4 Gearbox and Transmission

• Manual: Smooth gear changes, without jerks or difficulty.
• Automatic (AL4/AT6): smooth gear changes, without jerks or delays.
• Fluids: Check the level and color (dark fluid or a burnt smell indicates the need for a change).

7.5 Electrical System and Panel

• Warning lights: Check all lights when starting the car; lights that turn off correctly after testing indicate normal operation.
• Sensors: Check the air conditioning, power windows, locks, and sound system.
• Battery and alternator: Test the load; a car with recurring electrical failures may indicate an alternator problem.

7.6 Air Conditioning and Comfort

• Turn on the air conditioning: the air should cool down in a few minutes.
• Test ventilation and airflow from all outlets.
• Check for noises in the compressor; strange odors indicate a dirty cabin filter or mold.

• Owner’s manual: Ensures maintenance records are kept.
• Maintenance notes: Check the service history, including oil changes, filters, and fluids.
• Vehicle tax and fines: Check for regular payments and any outstanding debts.
