I can't find any errors with delphi testning.
a new battery sensor didn't solve the problem either.
there is a post about the same problem but I can't see if the problem is solved

Start/stop light? Which one is this?

I am assuming it is the Intelligent Stop and Go indication on his dashboard display.

What colour is the ISG indication? Maybe post a photo here would help you describe the problem better.

It's the A for the isg light, it is yellow all the time, I've changed the battery and the battery sensor, but it didn't help

One or two things in this list need updating, but here's something to consider...

I30 Intelligent Stop and Go (ISG)

I read "somewhere" that some battery management systems need to be restarted after batt replacement and it was done by taking out and in  off one of fuses, supplying batt mon module. Below you can read that batt mon module, like dozens of others, can block ISG
