I had the same problem with my brava.my mechanic checked it and said the bulb is gone but it willcost more to raplace it as it is the entire panel (digital Speedo display) which needs changing.interestingly i can still see the readingd if i look in the day light.have a look for the fuse also...if it's expensive to replace...better leave it that way...hope you will be able to sort it...goodluck...pram
As my neighbour and pramodkumart said, you should try checking the fuse and if you want to know what fuse is it, check the www.fiatboo.co.uk site and there you have the fuse scheme. Go to index on this site and find fuses and that's it! I hope you will find the fuse because everything you do is to expensive, FIAT!
It's a bulb gone at the back of the gauges. Sometimes they've been known to just come back on again, especially with a helpful thump.
To remove, drop the steering wheel down as low as you can, remove the 3 allen securing screws around the instrument hood and then two lower ones which you'll see when you drop down the wheel. Now there's also a phillips screw nicely hidden away behind the dash. To get access remove the fuse box cover then get yourself upside down with a torch and you 'll find it.
Then you can manoeuvre the gauge panel out far enough so you can remove the wiring connectors and then you can withdraw the gauge panel.
