I have a new colt, and when it's cold, the engine makes a rattling noise. It occours shortly just before the RPMs drop to idle. It's not a ticking sound, more like a handful of nails was dropped in the engine? After 3 to 5 minutes it goes away.

I´ve already made an appointment with the garage, as it´s covered by the warranty, but DAMN im itching to know what makes my car acting like this after only 5000 miles.

If anyone can answer me, bear in mind, that i´m danish, (the explanation as to why this post is so faulty written) and a simple answer would be greatly appreciated ![:@][:@]

 

Mercedes Benz Chain Driven engines thats why!

 

I just picked it up at the garage, and it turned out to be bolts on the manifold that needed tightening.
