Petrol-specific checks on the Mercedes-Benz S-Class

  • Cold-start behaviour. A genuine cold start reveals knocks, smoke and rough running that a warmed-up engine hides.
  • Timing chain or belt. We listen for chain rattle on start-up and check belt service history, because a skipped interval here is one of the most expensive engine faults to put right.
  • Carbon build-up. Direct-injection petrol engines are prone to intake carbon; we look for rough idle, misfires and the symptoms that come with it.
  • Oil consumption. We check oil level and condition and ask the right questions about top-ups, since heavy consumption points to worn rings or seals.
  • Cooling system. Water pump, thermostat and coolant condition are inspected for leaks and overheating risk.
