New owner help please
 

Hi guys

New to a volvo this is my first time owning one.
Iv got a 2008 V50 se 2.0D
It goes very well when cold but when it warms up seems as if its losing power like a turbo not kicking in. Runs fine but just dont give that kick.
Does not smoke etc but is a little miss fire on idle every 10 or so seconds but thats it.
Any ideas guys many thanks

Any idea please thanks
