DONE it too!!!
I went to the dealer yesterday and told them i want this to be done. I also mentioned that it is doable

. They took the car into the garage and connected it with the FIAT Computer and after 2 minutes the mechanic comes along and asks if i have the personal code. Gave them the code and 2 minutes after BLINKER is on.
Feels very good to know if your car is locked.
Thanx gays
PS: I don't have an alarm system fitted.
PS2: If they couldn't do it [pantjo] i would have come a trip to Greece and visited your dealer
