I am looking at purchasing a code reader for my two mercedes. It seems that because of the difference in age,
i may have to get two different code readers from what I understand...
First, lets start with what I have- a 1994 S320. Can someone please tell me what kind of code reader I need to look for to work with this car.
The other is easier i hope, a 98 ML320, from what I understand is OBDII compliant. So any OBDII reader should work right?
I dont need to get too fancy with the diagnostics, I just want to be able to check codes and reset engine and oil change lights. I just want to be ahead of the game when I take my cars in...
So if anyone has a code reader(reasonable) that can read both cars, please share. If im going to need two, send me a list...Id like to get one soon, my check engine light came on in my S320, and my SRS light is still staying on for around 40 sec after car is started before it goes off...

Thanks in advance for your help.
