So it’s been a few months that my 1.8TSI is shutting down while I am slowing down or hit the brake, when the car shut down the battery light is on (I replaced the battery 4 months ago, checked it and it’s all good).

 

looking for help with this issue.

 

and another thing, someone knows which part of the car is it in the picture below?

Do you get any error/fault codes if you connect any diagnostic tool?
