Sorry to reply late to this, only just come over here from the Multipla forum. My wife has a petrol Idea, brought new last year. We were annoyed to find that, unlike every other car we've owned with remote locking, the indicators didn't flash when armed/disarmed.
After a long talk with the service manager he said "Yes the indicators can be set to flash, but your car has been set up not to do that".
This was the the garage that had just sold us the new car (Ted Johnson, Barnsley), and the guy cheerily told us that it would be 50 quid to alter the ECU to make the indicators flash. We were so annoyed at this that we walked out, never to return, and we've gone to another dealer for all our servicing, and brought our son's Punto Grande from, Fiat Piccadilly, Wakefield- (highly recommended).
We bit our tongues and paid to have the alteration, and now the indicators do flash whenever the system is armed or disarmed.
At the time we were going to write to Fiat and complain, but I'm ashamed to say we never got round to it.
