Few days ago I noticed a burned smell. It smells like burned oil or something similar. This smell comming only after 5-10 minutes drive when engine gets almost normal temerature, and dissapering after 2-5 min. Happen from time to time (once a 3-4 days). You can feel this smell inside and outsiede car. Somewhere from engine area, but difficult to find it exactly. No red lights, no warnings.
What it can be? Smell from DPF? Unfortunatelly my guarantee is gone few weeks ago and I starting to be little bit woried.....
Any ideas?

There was a recall to change something on the car about a year or two ago so yours might not have been done  Former Mod/Member, with the most post & Chicken George Arch nemesis
