2001 Renault Megane 2001 Renault Megane

You can just change one .. but I recommend changeing all 4 together as the break down in sequence so if you change one .. then 2 days or 2 weeks later you will be changeing another then another etc. do this simple test ... start the vehicle let it sit ticking over .. go under bonnet and unplug the little wiring connector to #1 coil .. the vehicle should stall out (stop running) do this test for all 4 one at a time .. if the car stays running when one of them is unplugged thats the bad one !! hope this helps .. let me know
