Clk w209 coupe engine rattle

[ash1212002]

<div class="bbWrapper">I've noticed in the morning not sure whether its all the time or only on occasions when I start the vehicle there is a rattle which clears after a few seconds<br /> <br /> I have read on the forums/google this could potentially be due to the timing chain being stretched or something to do with the oil, I was under the impression the earlier clk's were only affected<br /> <br /> a local merc specialist has recommended I replace the chain as a preventative measure, and if I do not bother it will cost me long term as I will then have to change the gears etc<br /> <br /> Can anyone put my mind at rest whether the rattle is due the timing chain or whether this is a characteristic of the vehicle, reg bf57vxd<br /> <br /> Cheers</div>
