    Hi
    My megane mk3 makes this distinctive tapping noise on idle, it doesnt sound right, It comes and goes every 20 seconds or so. Timing belt was changed last year at 100k km, i have checked the glow plugs (resistance check) and they appear to be fine. If any renault guys have heard this before on the 1.5dci engine id like to know what you think.

    Im not a Renault guy but that sounds very like diesel knock possibly caused by a faulty injector. A leak back test is in order would be my advice
