Re: 50 seconds of rattle on startup

Thanks for the info. The noise actually stops a few seconds before the revs drop - hopefully it's audible here, the dropoff is about 45-50 seconds after startup:

Re: 50 seconds of rattle on startup

Hi,

It doesn't rattle after it's dropped down to 800RPM, even if you push the RPM up afterwards.

Is the timing chain or tensioner something that is supposed to be replaced every X miles/years, or are they supposed to last the life of the engine?

Thanks,

50 seconds of rattle on startup

Hi, Car is a 2012 2.0 TSI, 101k miles, just bought. On startup from cold, for about 50 seconds the RPM goes to about 1200, then settles back to 800. During this time, there is a rattle from the offside of the engine that goes away once it drops to 800 RPM. Any thoughts on what this might relate to? ...
