edz61, before new cars (not only Porsche's) leave the factory they get a country specific coding dependent on the region the car is sold to. The coding is needed to fulfill different legal requirements or to better suit different habits in different countries. E.g., cars for the US get a coding that could contain things like a beep when the ignition is switched off and the key is not removed before the driver's door is opened. Or different texts and symbols displayed in the instrument cluster's display regarding cruise control and brake related stuff. Cars for the Saudi-Arabia region get that repeating chime above 120km/h to remind drivers of the 120km/h speed limit in SA. Since jimy_q is from Dubai his car originally got SA coding with that annoying speed limit chime.
