hey guys, apart from regular maint and doing the head gasket on this car, I'm still a mb newbie. while driving a very long distance today, I got a check engine light while up in the mountains in the middle of nowhere. the car drove and made it back like a champ though. I was slightly worried about being stranded and being attacked by wolves really!

I did a search and found some posts about later 124 models ailing from the same light. none mentioned how I should pull a code. the vehicle is a 88 300e, hence my name. how do I pull a code on this vehicle?? I read about a black box with a switch and led. press for 2-4 seconds and then what happens? please verify. obd2 and scan tools have spoiled me and made me ignorant. I thank you in advance, I need to get this solved so I can drive with confidence.

you can go to autozone and have them pull out the bad codes for you...it's next to the battery, the black box, underneath is the button...

I prefer to stay out of autozone. ok so I push the button and count how many times the led blinks? thats it? thanks for responding.

I need to purchase equipment for this?
install on-off readout ratio tester? connect impluse counter? if I do, that just sucks.

I found the port. held the button down for 2-3 seconds and #4led blinked 8 times. thats it. I will try and search around. if you know what this means, please inform me. thanks. I will check in the link posted above but those codes are listed as 90 and above. mine is a 88. would they be the same codes?
