Hiya.
Had a Mercedes in for a service today. I think it was a 200 class. 2 litre 4 cylinder, automatic. I found a dipstick tube for the autobox, but it had what looked like an anti tamper proof plastic top. I managed to remove it, but no dipstick was attached. It didn't look like it had broken off. It also says 'MB Workshop Only' - Or something similar. Do they have a tool to dip the oil at MB workshops to stop anyone else checking it? I had to send the customer to the local MB dealer, which I don't like doing!
