How do you reset service light on ML350 with a 164 chassis number?

Need to do service confirmed:

1- Door closed key position 1 (make sure you have the temp. screen up before starting) immediatly after turning to posistion one, press the reset button 3 times. and the battery voltage should come up.

2- page down to serivce data menu. Use plus and minus to select service data and hit page down to select.

3- Use plus and minus to scroll down to "confirm overall service" , then hit page down. It should say service confirmed.

4- Take the key out ant put back at position 2, the service message should be gone

I had the same issues with trying to reset the service codes for my M/B ML350. After looking everywhere and getting no help from the Mercedes dealerships, it turns out, the directions for resetting my service codes were right in my owners manual! I tried it and it worked the first time........I just can't figure out why Mercedes wouldn't tell their owners such a simple solution to a very irritating problem!
