Q: IM608 II Renew 2013 Benz S Class ECU Login System Error?

I’m trying to versionize an ECU of a 2013 Mercedes S Class. It’s an MED17.7 ECU. When I hook it up to the G-Box3, I get a screen that says:

“The system requires waiting when requesting to login the system.

Waiting in progress…

Please keep the system in a powered state. A waiting time of 30 min is needed at most. If you want to cancel waiting, please press Cancel.”

I had it there for several hours, but it does not log in.


A: This is because Autel servers are receiving a significant demand of users who are trying to do the same procedure. What Autel did was they implemented some sort of Q system for that particular function.

You can continue to wait until the calculation is completed or cancel the operation. Just come and do it again at a different time when there’s not a lot of users on the system.

I have one working key and want to add 2 additional keys. I was able to register the key but the remotes are not working. Because there’s something I did wrong.


A: This is because the original working key that came with the vehicle remote also wasn’t working. So if the original key remotes are not working, this tells that you have an underlying condition. The first thins should do is to scan for codes:

  1. Check for codes
  2. Check the (RFA) module
  3. Check the BCM


After clearing the codes, then continue to do key programming.
