Official recalls: ask before you pay

We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.

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.

On the test drive: what to look and listen for

0 of 3 checked

Timing / lubrication

Oil-bath timing belt degradation
Look out for: Oil pressure warning, hard brake pedal or reduced assistance, oil consumption, blue smoke, squeal at the front of the engine, turbo whistles or loses power.
Ask them to check: Measure the belt through the oil filler opening with the manufacturer's tool. Confirm whether the vacuum pump campaign was done.

Automatic gearbox

EAT6/EAT8 jerking and torque converter
Look out for: Hesitation or a jolt between 1st and 2nd, torque converter shudder in traffic, harsh or delayed shifts and a gearbox fault warning, especially on 2017–2019 3008s.
Ask them to check: Check oil level and condition, update the gearbox software at the dealer and, after an oil change, record it with DiagBox and reset the adaptations.

Bodywork

Interior door handles that deactivate with the engine running (308, 408, 3008, 5008, C5 X, DS 4 and DS N°8)
Look out for: With the car switched on, one or all four doors cannot be opened from inside.
Ask them to check: Check the campaign by VIN at the dealer; meanwhile, test the interior handles with the car switched on.
