Please could someone help me with the Removal and fitting of cam chain and adjuster on the 2011 C180 CGi my wife has. It has done 46000 miles and has developed the dreaded rattle on startup and twice has not started on the first turn of the key. I have been in touch with a local Mercedes dealer who by the way was a nice chap. He said because my car has had two owners, my wife being the second. Mercedes would not even consider any form of help for the problem we have. Two years out of manufacturers warranty is too long in his opinion, and I tend to go along with that. So I am very handy spanners as I actually owned a garage a number of years ago so I would like to do the repair myself. First thing is I would buy a workshop manual to help me do the job but I only have macs at home and at work and the manuals are only windows based, so I can not read them. Next thing is I have heard that the cam adjuster has been modifies and so has the chain. So do I get genuine Merc parts or do I go for Febi Bilstein. The Febi parts I take it are copies of the original parts and not any modified Merc parts. But the Mec parts have failed and maybe could fail again. I think I am very confident in changing the chain, but the tensioner I find a little baffling. Also is it OK to use the split link supplied with the chain to join it. All the old Mers used to have the chains joined this way. Can anyone give me details of how I should go about changing the adjuster and guides please. Do I have to take the lower part of the cam cover front off to do this?. Any help will be greatly appreciated.
