I copied this procedure from an old thread, I somehow disabled the top marker lights. Anybody can steer me to how to turn them back on?
Finally, you will need to get an OBDII adapter. I had mixed result with a cheap ELM327 but the OBDLink MX+ worked flawlessly every time. Plug the yellow cable to the OBDII port of the car and the OBDII reader to the other end of the yellow cable. Open AlfaOBD then go into "Car configuration change" and switch the following values to off:
Turn Signal Diagnostics
Back-up Lamps Diagnostics
Brake Lamps Diagnostics
DRL Diagnostics
If you want to keep your fog light on while turning on the high beams switch the following configuration to off as well: Front Fog Light Drop-out
