Hello All....So my 2007 CLS 550 has started running rough. Took it to my mechanic and after a tune up still running rough.
He hooked it up to the computer and it read....

0629 Misfiring (p0300)
0645 Misfiring of cylinder 2: damages TWC (p0302)
0633 Misfiring of cylinder 1: damages TWC (p0301)

Anyone know what these codes are and what is the repair procedures??

Thanks for any help

Just in case you didn't know, you are on the wrong section. Your car is a 219.218's have a smaller TT engine.

Could be a couple of things. Cylinder Coils are bad, spark plug went foul, and many other reasons. Find a shop to check those two cylinders.
