3 Malfunctions: ABS, BAS and ESP. Need help.
When I got home I disconnected the battery (to reset the system).
I also steered all left and then right and back to center and stoppes the car. (to reset the steering angle sensor? )
I also removed all tires and checked that everythings were fine. (everything looked ok )
After these "rituals" the car worked perfectly. For two weeks...
Today this happend again, and I start thinking it might be some serious repairs to do on this car...
But I hope someone in here have some tips and would like to share them with me

I apologize for the bad English.

I changed my brake switch and it didn't make a difference. I realized it was just a couple of fuses

and as a little side note, make sure the little white plunger on the new brake switch is the same length as the OEM one you take out. You can adjust the new one by pushing the white part all the way in and then pulling it out slowly so that you can match the lengths up

The problem has occurred almost every time after a short stop at traffic intersections. When I start driving again and starts to press the gas pedal, it feels as if the car loses power, and then 1-3 seconds later all the lights come on (ABS, BAS, ESC, ESP). And few seconds later the motor stops by itself. Most likely is the car putting itself into emergency mode. This problem have I struggled with for 6 months now. And my local Mercedes repair shop has not managed to solve the problem. They have run diagnostics on the car and tried to guess which part who needs to be replaced.
They have changed the Brake Light Switch and Steering Angle Sensor so far. But the problem is not solved.
Please read this. I need help from you.
Here is the diagnosis assistance system test:

I am not sure they did remove all the faulty codes, but that should be the first thing they try right?
My bad! This diagnosis is taken before they replaced the steering angle sensor.
The steering angle sensor is replaced, and the car is programmed so the car knows it got a new sensor.

I've read about a similar issue if the reluctor rings corrode on the hubs/drive shafts as they send the wheel speed signal to the ECUs. But I can't see any related codes on your print-outs. Sorry, I do not know what to suggest ohter than an MB specialist
On the plus side you should be able to rule out the brake light switch
