Hi,

The item you are describing is the EGR valve, it is a valve that recycles some of the exhaust gasses back into he engine intake to reduce the missions.

These units run at extremely high temperature and can fracture and leak gasses, it sounds like this has happened in your case, in my view you must have the part changed immediately as the hit gasses emitted from this are a fire risk, as can be seen from the burnt heat cover and engine cover.

I hope this provides some advice to you, please remember your deposit doesn't pay me for my advice, please rate my answer. If you have any further questions on this subject please don't hesitate to ask.

Best regards
