Engine-noise ??
Does anyone know if this noise from the engine is normal ??
the engine is an M273 and definately not a diesel engine..
Sorry for the unsteady images ,but I tried to capture the rattle a good as possible.
If this is not normal what do you guys think could cause this?
To my personal opinion this is a timing-chain or something,but I could be wrong and this sound is completely normal etc..
Another clip :
The engine has only 82000Kms on it and not throwing any 1200 or 1203 fault-codes such as yet..

It is not misfiring or idling unround ,just a rattling noise that is worrying me , no check engine or codes, so far..
There seems to be a material issue in the timing-sprocket in the early M273- engines ..I did some research.. eventually it will start throwing codes 1200 and 1203 ..if this is the cause of my noise, I just do not want to wait until this happens might be too late.
I was hoping anyone on the forum recognizes this noise ..
Sure ,I will let you guys know ,as soon as I know more, hopefully this week..

Well ,here is the promised update:
got my car back from the dealer today.
They took my complaint very seriously and have done extensive research on the car.
I was allowed to have a look in the tech report what they have done on the car etc.
They have replaced one of the timing-chain tensioners, checked the timing-'chain-stretch' they also have 'de-aired' the automatic gearbox,as well as several software checks and updates.+ very importantly : their warranty that all is well :-)
Now I have it back without any costs and they asked me to be back if I have anymore worries.
Such a great service from this dealership here in The Hague in Netherlands!
Have driven the car an hour or two only,today and sounds like that noise is gone, but since it was intermitting its difficult to be definite on the conclusion..
So far really happy that I got extended warranty and this very MB-dealership, hopefully problem is solved.
