Common Problems with the
2002 Renault Megane Mk2

Launched in late 2002, the Mégane Mk2 shook the family hatchback class with avant-garde styling, a 5-star Euro NCAP rating, Renault Card keyless ignition, and a refined line-up of 16V petrol and dCi diesel engines.

What changed for 2002

  • •Radical Patrick le Quément 'shaking that ass' styling with architectural vertical rear window line
  • •First vehicle in the compact family class to achieve the maximum 5-star Euro NCAP crash-test rating
  • •Introduction of credit-card-style Renault Card ignition key and aviation-style aircraft handbrake lever
  • •Launch engine line-up featuring 1.4 16V (98hp), 1.6 16V (115hp), and fuel-efficient 1.5 dCi common-rail diesels

Common MOT watch-outs

  • !Snapped front coil springs and cracked spring top mounts, particularly over UK traffic-calming humps
  • !Headlamp beam pattern failure caused by misaligned H7 bulbs inserted through cramped wheel-arch access flaps
  • !Worn front lower suspension arm rear bushes and anti-roll bar drop links failing roadworthiness checks
  • !Diesel exhaust emissions failure caused by worn injectors or soot-clogged EGR valves on early dCi units

Buying Tips for 2002 Renault Megane Mk2

  • Test both key cards repeatedly for remote locking and engine cranking; replacement cards require specialist coding
  • Check front footwell carpets for dampness caused by blocked scuttle drain grommets which drown the cabin fuse box
  • Verify operation of all electric windows; plastic regulator clips frequently break and drop glass into the doors
