  • Engine running irregularities or starting difficulties
  • Electronic equipment controlled via CAN-bus not working correctly
  • Transmission shifting with delay, jerking, or not shifting at all
  • Planning to purchase a used SEAT car — diagnostics will help objectively assess its technical condition
