Hi, Dont quote me on this, but i had problems with my laguna 2 , 3.0L V6. Started fine, drove it for a while then it just died on me. I got a friend (Renault Mechanic) to do a diagnostic test and he found that one of the TDC sensors was not working, The engine management system seems to stop any power going to the spark plugs, if this fault occurs.If the TDC Sensor on a Megane1 1.4 16v is failing/failed what symptons would be most obvious?
Uneven engine tick-over?
Lack of power?
