Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
The service bulletin is due to poor throttle response in reprogramming the computer.This does not sound to have resolved this issue here.
If you know the fault code number setting with this issue from the dealer when they checked the fault codes let me know here as this will help.
This will not hurt to operate the vehicle like this but there is an issue here that does need addressed and repaired.It sounds like the dealer may be at a loss on this fault.If they have not contacted their tech support I would ask them if they can contact their tech support to see if they can get any help and ideas of what to check and repair for this fault here.
Since this occurs up a steep hill this may be fuel related.An issue that may not be causing any driving issues but may be enough for the engine warning light to come on indicating an issue is present needing looked into and repaired.I have seen restricted fuel filters as well as a weak fuel pump cause the light to come on but no running issues.

Did these codes
102001 from what I see is air mass flow sensor input to high.
120308 charge air pressure to high
If your mass air flow sensor is dirty or reading incorrectly needing cleaned or replaced this will cause the issue you see here.I would focus on having this checked and cleaned if possible or replaced then clear out all codes and make sure engine air filter is clean.
