Hi people. 6 months ago i have got my 2014 W205 220d with 62k miles, nothing wrong with it, car drives and behaves as it should however, from a while i started hearing a ratteling noise every time i accelerate it, when on idle the engime sounds smooth but every time i start accelerating to drive it, the noise starts.
 
Is it not just the grumbly diesel engine ? My 250cdi E class coupe sounds decidedly grumbly when cold and when sat in traffic but you get used to it at motorway speeds.

I’ve driven 3 others now and they are all the same

Hi. Thanks for replying.
I Know what you refer about diesel engine "normal" rattle sound. This one is different, is a ticking ratteling sound

As it's a new noise and not one you'd expect with this engine, IMO there is something going on
Often these nosies are associated with timing chain/or tensioner - faulty exhaust/fittings.
I recall seeing a youtube vlog on some diesel car a few years ago it was a diesel engine and it rattled on acceleration,
IIRC it was something that was associated with the engine valves, springs/ tensioners/adjusters not sure, can't recall but that gave a rattle on harder acceleration.
Start with the simple bits get the car looked at, just tell them what you told us but not what you think it is unless they cn't think of anything and see what they say.

I much appreciate your reply. Will get it checked.
