Hi all, New to this forum so please excuse my lack of knowledge on its use. So, the story is, I have just bought my son a 2005 C220 CDI which doesn't have a dipstick just a red plug on the dipstick tube. I have been told that you can either access the oil level menu via the dash controls or you can purchase a dipstick. After much searching I have not managed to find out if this is true but if anyone could point me in the right direction I would most grateful...shaun
