Before you buy a used Citroën C6.
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.
The essentials.
- 2 documented, sourced faults across its 2 engines.
- That is not much data: if no other faults show up here, it does not mean it has none.
- 1 official recall on record: ask for the chassis number (VIN) and confirm it has been done.
- According to the data we have, the engine with the fewest documented faults is the 3.0 V6 (Petrol).

Official recalls: ask before you pay
A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.
- Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
- Ask an official Citroën dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
- Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

Suspension and steering
Look out for: Wishbone bushes worn after just three years; the inner shoulder of the tyres wears when straddling speed cushions; a difficult alignment that few garages get right.
Ask them to check: Check the bushes and inner tyre wear; have the alignment done by an experienced garage.
DPF / EGR / turbo / flywheel
Look out for: Particulate filter warning and power loss; rough idle from a dirty EGR; vibration and knocks when starting or in low gears (dual-mass flywheel); smoke or hesitation from injectors at high mileage.
Ask them to check: Read the DPF status and additive level, check the EGR and cooler, check the dual-mass flywheel at start-up and measure injector balance rates.
