Hey all, looking for ALDL port(s) in my 1994 500S 2DR.
The vehicle has lodged a code, and the check engine light has been lit since.
I am hoping my OBD2 reader will pull and clear code, but after searching under every combination of code, reader, port, plug, ALDL, OBD 1 and 2, I have found nothing germain to year and model. I can fabricate any required harness but want to make sure I'm heading down the right path before putting on my boots, and backpack!!

I'll be up a while so hit me!!!!

Neither OBD1 nor OBD2 were present in the 95 S500/S600/S320. OBD2 Started in 95 for the SL series, and 96 for the rest of the lign-up of cars.

You need Car Soft or MB Star to decode, and to clear Limp Mode and other faults...

Here are some links on the testers, but I suggest you get MB Star...

Since you have a W140, the weak point that can destroy the engine in under a minute is the heater tee on the drivers side of the fire wall. The plastic tee is safely good for 70k to 80k miles, and I replace it with a Rein brand(who make the mercedes one), or an actual Mercedes one-No ebay, Euro, or used tee's. If you do not know when it was changed, change that sucker..Here are some stories to motivate you..
