My 270cdi makes more noise when cold, especially below zero degrees centigrade, and minor vibration which clears after it warms up, this takes about 10 miles.

I have also quietened motor noise by insulating a few weak spots in the 'firewall'; it only takes a hole the size of a pin to transmit considerable noise.

Having said all that, of course, I cannot tell how much vibration you are experiencing. I would report it as it is under warranty.

thanks for your reply
Another thing to think of is fuel, these engines are quite sensitive to fuel quality.

I find supermarket or unbranded diesel a false economy, it might not be properly winterised, it may not have the proper level of additives to keep the injectors clean and I find the mpg falling from 28 to 26 (miles per imperial gallon) at least.

Try a different brand of diesel and see if your vibration is less.
