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 Mercedes-Benz 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

Taken from each sheet's symptoms and checks. You can tick off what you have already looked at: it is saved only in this browser.

0 of 3 checked

AdBlue / DPF / EGR

  • Look out for: AdBlue or emissions warnings with a start countdown; particulate filter warning; power loss or rough idle from a dirty EGR.

    Ask them to check: Read AdBlue and NOx sensor codes with Xentry, check the particulate filter regeneration history and how the car is used (short trips).

Timing system

  • Look out for: Rattling on start-up, the engine warning light and camshaft-timing fault codes; in serious cases, engine damage.

    Ask them to check: Listen to a cold start; read the engine fault memory; ask for the service history with on-time oil changes and ask the dealer what fix exists for the adjusters.

Engine

  • Look out for: Mild-hybrid system warnings, loss of EQ Boost and weaker acceleration; turbo overheating if the auxiliary pump fails; at high mileage, carbon on the intake valves.

    Ask them to check: Read the 48 V system fault memory; check campaigns and bulletins by VIN; stick to the oil-change intervals.
