    Default C5 Rattle

    Hi All,

    Have developed an unwelcome rattle seeming to be coming from 'deep within'.

    The video below best characterises the problem.

    That's distinctive. I bet someone here will know it. I wonder if it's the sound the alternator clutch makes if it's about to fail.

    HDi? What year? If it's an HDi, I'd guess either the alternator pulley one-way clutch is frozen or the 3 part damper is about to fall apart. It depends on what your car has. For the HDi, it should have either a fixed alternator pulley and a 3 part damper OR a one-way clutch in the alternator pulley and a 2 part damper. As the noise has suddenly started, it shouldn't have an incorrect mixture of bits. If the alternator pulley is held on by a nut, then it's most likely the crank pulley at fault. Does it have a plastic cap where the nut would usually be? If so, then it's probably a one-way clutch inside the pulley. It sounds more like a 3 piece crank pulley with failed rubber bonding. If the crank pulley falls apart, your timing belt is at risk and that can ruin your engine. Better to seek proper inspection/diagnosis by a mechanic.

    thanks a lot for the feedback.

    It is indeed an HDI- I will have to get back to you on model- I think 2003/4.

    I will start looking for a solid mechanic- if you can recommend any in Brisbane- let me know!

    Thanks again!

    Euroserve in Newstead would be my first call.
