Thanks again Neil. My car is going to see the doc this Saturday. Hope he can find out what is wrong with it and has a simple and cheap solution. Unfortunately over here, its always an expensive solution and you don't know if it is the correct one too! I find that they always discover something is wrong even if there isn't any and want to replace things. Otherwise they will get you a long list of "failing or failed" parts which are questionable for us people who are not in this repair game.
More opinions and assistance are awaited from other Benz owners and techs, thanks.
