Hello Noxide! Yes It is so worth going to the fiat dealership to get a diagnostic done as they updated the system and my problem is fixed! I have driven the car 200 miles and reached 70mph - no lights !! yours seems like a similar problem !

Technical HELP stop and start unavailable/warning light/engine light
Glad it's sorted. From service history you quoted, first two done a little later than I would want even if it's 18k in the schedule. I know nothing but I'd have the oil changed at 68k ahead of winter or along with belt kit. Not sure if the 600 mile or fortnightly checks mentioned in the handbook in your case but I've followed religiously with 4 Pandas and been fine but they've all been relatively new.
It seems like my daughter has the same/similiar issue with her Fiat 500.
The EOBD injection system failure light flickering on at around 70 mph, with the triangle warning light and stop/start light coming on. When she switches off-on the engine the warning lights disappear and there is no default code stored in the system according to the local garage diagnostic. The engine seems to be running fine. The coil pack had already been replace the previous month when the same warning lights came on (and stay on) but at much lower speed and the engine was obviously misfiring. The car also had a full service and the cambelt replaced.
Sounds like a visit to a fiat dealership and an update to the ECU software might resolve the problem. Thanks for the hints

Has the car had a timing belt replaced reacently?
Edit just noticed the bit where you said it had a belt replaced reacently
As a flashing light and misfire code at speed is a common sign of the car needing a. "phonic wheel relearn" this should be done whenever the belt is replaced but lots of garages don't know about this procedure

thanks for the TIP
I googled around and saw an example of a "phonic wheel relearn" for a fiat punto, basically let the engine warm up then bring the rev speed up to 4/6000 rpm 3 times while letting it come back to idle inbetween. I wonder if it is the same procedure for a 500 and if it is worth a shot trying first before taking it a dealer/garage?
Strangely the car was driven four times yesterday twice in the morning for 45 mins, twice in the afternoon again 45 mins (about 25 mins on the motorway), the first 3 times the light came on but for the last journey it didn't. This morning it was driven twice (same journey with a 2 minute stop in between) and no light came on.

This seems to me a completely reckless thing to do if you have any reason to suspect the valve timing might not be correct.
Which 1.2 engine is fitted?
If it is the one with variable valve timing did the garage use the special tools when changing the cam belt?
All 1.2 500's have VVT.
The 60HP engine (the one with the safe cambelt) wasn't used in the 500, though it was used in the 1.2 Panda until about mid 2010.
It's a good question, though; the forum is littered with posts from folks who've experienced issues after a cambelt change. It's one of the jobs on a 500 that I wouldn't trust a non-fiat specialist with.

So a quick update about my Daughters car.
It took a couple of weeks before a free slot for diagnostic test was available at the local main dealer. The initial diagnostic (£120) revealed misfiring in cylinders 2 & 3 but they said they needed to make a further investigation to find out the problem.. They carried out a timing check and discovered that the tooth timing was out by one tooth. They gave the option to replace the cam belt with an approved dealer part (extra £110 with a 1 year guarantee) or just to make the adjustment to the generic one installed by the local garage. We choose the later option to keep the costs down, the total cost was £240.
The light hasn't come on since so we think everything is fixed.

Let’s hope your problems are behind you now! On a side note ... you could have just paid €50 for a registered version of multiecuscan got your own leads and disgnosed that yourself then added the rest of what you paid to get a brand new timing belt!
Did they check the water pump at the same time? I would assume they did let’s hope so!
A new coil pack & leads are quite cheap to buy & even cheaper to fit... I did mine myself
