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.

  1. 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.
  2. Ask an official Peugeot 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.
  3. 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 4 checked

Exhaust and emissions (AdBlue)

  • Look out for: Emission system fault message and a “starting impossible in X km” countdown, AdBlue/UREA warning and engine light.

    Ask them to check: Diagnose with Diagbox or equivalent: AdBlue pressure, flow test and tank temperature.

Timing system

  • Look out for: Rattle from the top of the engine, loss of power; in severe cases the chain breaks and the engine fails.

    Ask them to check: Ask the dealer whether the car is in the campaign (free inspection and replacement if needed) and whether the 8 mm chain is fitted.

High-voltage battery

  • Look out for: Usually none. In severe cases, smoke, overheating or a battery fire.

    Ask them to check: Confirm by VIN that the battery recalls have been done and look for rust on the battery box.

Automatic gearbox

  • 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.
