Family friend brought their 10K mile C320 to my home so that I can show them how to change engine oil. They like to be able to change the oil half way between the "flex" service interval.
The hood is hard to open, there is something that catches. The feel is much worse than wife's 98 C280.
The engine is new to me so I look around trying to find that "dip stick". There is none to be found. I did find a tube which is "open" at the back of the engine. I think their engine and air "communicates".
PS: After complaining to the "stealer" regarding the open pipe, the stealer is happy to sell them the cap.
