Check a car before buyingSearch a fault codeCompare models

Common problems

  • N47 timing-chain noise on earlier cars and poor service history.
  • B47 EGR cooler, DPF loading, and sensor-related emissions faults.
  • Oil leaks around filter housing, valve cover, or turbo oil lines.
  • Automatic gearbox shudder or delayed engagement when fluid service is ignored.

Symptoms to take seriously

  • Rattle on cold start or at the rear of the engine bay.
  • Reduced power, smoke, or frequent DPF regeneration.
  • Coolant smell, oil residue, or uneven idle.
  • Harsh 2-3 shifts, vibration on lock-up, or delayed reverse.

Checks before buying

Confirm whether the car uses N47 or B47 and check invoices by mileage/date.
Scan engine, gearbox, ABS, and emissions modules before and after the test drive.
Inspect EGR, DPF readiness, boost data, coolant level, and oil leak evidence.
Budget for fluids, filters, thermostat/cooling work, and any missing gearbox service.
