Hi guys, I have a few questions here.
I have a 2003 clk500 with about 58k miles on it. I have developed a slow tranny leak from the pan that has been leaking for a few weeks now and my plan was to just change the filter and put a new gasket and fluid in it anyway. Just yesterday my check engine light came on. Now if this would have happened on the hondas and nissans I have owned before I would know it is usually an emissions prob since that is most commonly what CELs are for. But this being a mercedes I was not sure if it could be related to my trans or anything else. So now that I have prefaced my situation here are my questions. Hope you can help.
1. Does the Mercedes dash have a diagnostic in it that will tell me the code and problem without a machine. Or do i have to go to autozone and have them pull a code. Where does it plug in?
2 I have 2 fluid tubes against the firewall and I need to know which one is oil and which one is for tranny fluid. I have seen the posts on here and the pictures seem like they are both pointing at the same tube. They both have black caps on them, but there is one that is easily accessable and there is one that can not be reached unless I remove the air filter box. The cap that is harder tp reach is black with a red button looking thing on it. Which is engine oil and which is tranny fluid.
Here's a partial answer - I'm not familiar with your engine.
1. You cannot read diagnostic codes on the dash cluster. The code reader plugs under your steering wheel. Next to the red hood release lever you will find a black plastic cover that flips open to reveal the diagnostic socket.
2. The tranny dipstick tube will have a plastic cap that should have an unbroken seal in place. The engine dipstick tube will just have a plastic cap - mine is red.
You should be able to read your engine oil level at the cluster. The CEL could well be warning for low ATF.
