2015 ML350 4MATIC + 1988 300E
Depends, it can be many different things on the California emissions model like I have.Isn't the CEL for the O2 sensors going bad? Mine comes on and off occasionally..
Well, I reset/cleared it and it has not come back on yet...TechGuru,
Did you figure it out or get an answer to your question? lol
Because my check engine light just came on while driving today. lol
Which light flashed and where did you look up the code?Note I have the Cali version.
I pressed the button by the battery and the light flashed 8 times.
Looked it up and it says "Altitude Correction Capsule".
Ok, WHERE is it? and what should I check?
You have the cali version.TechGuru, tuttebenne and Funky Mad,
I have a 1989 300E. I live in California so I think this car is a Cali version but I could be wrong. Where would you know or find that out anyways?
Okay, I think this is the place forward of the battery, a L shaped covered port, theres a red light which is suppose to flash codes.
Theres also 1-8 ports to put something in. Im sorry if Im not using the right words but Ive never pulled codes off any car before.
Okay so heres a pic or two of the area near the battery.

and here is the round port on the right side of the engine bay if your looking at the car from the front, with many ports to plug in connectors.
there should be a name like RSLFTF (rightside looking from the front)

Where do I start.
-Is there a DIY instrustions year specific that you followed?
(looked in DIY but didnt find, but maybe overlooked)
-Can you make a link or maybe we can add a clean thread of how to do code reading in the DIY section?
Do you know where theres a code page to tell you what the number of flashing lights mean from start to finish DIY procedures?
