Mercedes W204 CDI Rattle Sound On Cold Start up
Was looking for some advice / guidance regarding the engine sound i hear on cold start every now and again not always on every cold start and only happens on cold start never warm starts on my w204 c200 cdi c class , 2012 , I hear this rattle sound it varies the exact sound , however i have uploaded it i have had timing chain checked it is fine and oil fliter replaced last year along with air fliter and fuel fliter , my machanic thought it might have been the engine cover not put on right bu this now does not seem to be the case..
any comments welcome
