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.

  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 Renault 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 2 checked

Timing / injection

  • Look out for: Chain noise at high mileage; loss of power and emissions warnings in town use; injectors that will not come out when removed.

    Ask them to check: Listen to the chain from cold, check injection and emissions codes, and before removing injectors have extraction tools ready. Keep oil changes up to date.

Known weak points

  • Look out for: Heavy rust on the subframe, window frames and rear suspension (the rear wags over ruts); a car that suddenly will not start because of a failed body control unit (UCH/BCM); on the 2.0 dCi, an emissions warning and loss of power from a full particulate filter.

    Ask them to check: Check the underside and rear suspension; ask about the ECU update; check campaigns by VIN.
