05 1.6 VVt Megane II - rattle on startup - Snakey
I have a 2005 Megane 1.6 VVt which has recently started to occasionally make a strange 'rattling' noise on startup. The only thing I can it sounds like is a bit like a football rattle!

When the noise occurs the car will generally start (sometimes takes a second attempt) and then runs fine for remainder of the journey (apart from some initial hesitation when cold - a trait of these cars I believe?)

The cars under warranty and is going back to the garage, but knowing Renaults poor dealer reputation I reckon knowledge is power and would be interested if anyone else has had a similar problem? A little bit of web searching brought up mentions of a dephaser pulley - all a bit too 'Star Trek' for a car!

Usually dephaser pulley or TDC Sensor.
Often when the pulley goes, MPG plummets.

Thanks for the info. MPG seems to be OK (around 38 on average) and the car runs fine otherwise.

I'll see what the garage try and fob me off with!
