Can Autozone check the codes on my 2001 E320, or is the computer system too complex for their reader. Is their any risk of damage from not using a Mercedes specialist. Thanks in advance.

PCM codes are required to be present at the under-dash OBD-II data link connector since '96 in the US. Those can be read and reset with that port. These codes also trigger the MIL (Check Engine light).

Unfortunately, your car has a bunch of computers that do not communicate with the ODB-II port, and an OBD-II reader is useless for them. So it depends on what's wrong.

Rlg,

I used to run to Auto Zone when I had a check engine light, or to clear a code..as was stated if it's a complex problem you may need the MB laptop.

I also found that if you buy the handheld computer for about 150 bucks....you will never see the check engine light again!

But, you will be a hero to your friends with a "check engine" light on..

I prefer Jeff's idea. Buy your own and learn how to use it. Simple instructions accompany these units. The $100-$150 unit connects underneath the steering area(approximate) and will pull what was mentioned above.

You'll save time and money and have the satisfaction of doing it yourself.

I wouldn't trust Auto Zone to predict a sun rise. Their employees like most of these mass-marketer chains don't know didly about automobiles. They do rent some half way decent tools for some situations and for things like motor oil, etc,. they are OK from a convenience perspective.

Thanks for all your input. I'll look into a DIY unit as mentioned. As of now, I'll probably take it to a good indy. Have a good one!

You've got that right!

Chris

I'll have to use that sometime. I've noticed a high level of wit here on the MB forum.
