Engine Light
The engine light came on my 2000 sl yesterday
I pulled the battery cable of and it went out It has not come on since Is this code stored in the system? Or am I kiding my self and the problem is still there and will be back Is there any way to read the codes without going to dealer and not spending a fortune ? I bought the new cd for it Did not find the spot were the codes are listed for the engine. I would appreciate any help Is the OBD11 scanner good for 2000 sl500 I am searching old threads also

If there is an emission related problem the light will come back ON.
NOT a good idea to disconnect the battery on SL's.. the computers don't like that!

Have seen ODB2 readers as low as $50 & higher.. any should provide codes.
90% of ODB2 codes are emission related. The rest are trans & traction system related.

I've done a search and can't find the code list from about 4 years ago that I saw posted. I can't even remember who posted it. My '91 300SE has a box on the passenger side firewall with an LED that flashes the codes for the check engine light. I can reset it here too and light goes out, does anyone have the code list, so many flashes means a particular problem. This is in a 91 126 not a '92 as someone thought back then.
Wonderful car I have, I'm just fixing the things that have worn out over the last 16 years, it will still run over 125 MPH (only second time I've done that) and the A/C still works.
