Help! I have an engine light on and after inspection I need to replace my catalytic convertors. I replaced my O2 sensors and that didn't help. I cant find any aftermarket parts for my car(2010 E550 coupe, Base). I found the left side cat on MBparts online but trying to look for a more cost efficient option if I can. If all else fails then MB will be last option. Thing is it's only the left side and the right side is discontinued. One muffler shop gave me aftermarket parts numbers but I believe its for the 4Matic (Left-645156, Right-645157). 1 seller on ebay says it wont fit my car cuz it is the for the 4Matic. I tried using Cataclean and so far it didn't work. I will try it one more time and go for a longer drive. Ive searched all over the internet for aftermarket parts and no luck with the right side.

Does the sedan Cats fit? and what are part numbers?
Any cat-back exhaust for sale?
Does the 4Matic parts fit?
Does the 2011-2013 coupe parts fit and are there any part numbers I can use to search.


Any options or ideas will be greatly appreciated MB world!!

Post your vin number, maybe someone on here can look it up for you.

Just a quick note, your 207 is actually based on the 204 C Class sedan. So if any sedan parts work, I'd look there.

With that being said fitment of certain bolt on parts can still differ. Has anyone out there successfully installed C sedan aftermarket parts? Im not really in a financial position right now to buy parts to test if they fit. Thank you for the response i will try to look further into this, Thank you!
