Without using diagnostic equipment to read the fault codes you are looking for a needle in a haystack, these are very complex systems, BAS/ABS and ESP are connected and also connected to large parts of the car.

 

Thank´s the codes that came out are:
C 1041 Can massage N47-5 ESP SPS (PML) and BAS control unit is faulty
C 1504-009 System fault steering angel sensor is not initialized

 

OK this is more helpful, given these codes it normally turns out to be the control unit that is faulty. The SPS is not initialized so first try to initialize it and here is how;

The engine should be running, then turn the steering wheel fully to the right and then fully to the left, do this several times. If SPS initialization is the real problem then when you initialize it the lights should go out.

If they do not go out then you need to physically examine the control unit. You can take it out and open it, check for white marks, ie water stains and rusty connections etc.

Here is the location of this module;

 

Thank you for the quick answer. I keep you posted

 

Hello again, I did what you suggested and now I have to wait and kip driving to see if this problem is solved.
Thanks for the help, if something happens I will posted again.

 

Are the lights out?

 

Yes the lights go out when I restart the engine every time that this problem appears.
