Buying Tips for the 2018 Renault Megane Mk4

  • ✓On EDC cars, do a full low-speed test rather than just cruising because hesitation and clutch shudder usually show up in traffic
  • ✓Blue dCi diesels should be scanned for stored NOx or AdBlue faults even if the dash is currently clear
  • ✓1.3 TCe petrols are worth checking for slow coolant loss around the thermostat housing after a long drive
  • ✓Make sure the R-Link or Easy Link system, digital dash and parking aids all work properly from a cold start
