Does anybody know how often you have to get this serviced. PVC 2005 Murvi Morello. Can't see any record in the paperwork of it ever been serviced. Seems to be a slight smell of fumes when on although carbon monoxide alarm didn't go off. Got a price yesterday from a Eberspacher agent in the North East, £200, bleeding hell I wanted it servicing not a price for a new one. Paul.
