vsa light wont turn on when i hold the vsa button and the vsa activation indication triangle /!\

Get a code reader and check your DTCs and any codes that appear let us know. Likely that a module failed or is shorted etc. The triangle being on the dash and refusing to come off means your car cannot activate VSA (traction control) for some reason or another and the codes will help diagnose it.

You might also check your abs sensors. That’s were part of the info. for the traction control system. Good luck
