First...thanks for the fast response Arthur Dalton. I can see by the forum that you are one of the gurus here and I am thankful for any and all your help.

Now comes the silly questions. I just went out, turned the key on (not starting the E320), and pressed the button beside the led in the led/sw. The led flashed 5 times and then stopped, but did not return anymore cycles or new codes. Is everything correct or should I literally have the vehicle motor idling.

Again, Thanks in advance.
