Hi. I'm new to this site - my wife owns a FIAT 500 1.2 Lounge Dualogic, registered in late 2012, and has done about 24000 miles. There is a flashing light on the dash indicating a gearbox fault. I have taken it to a local mechanic who has a diagnostic tool. I can't remember the fault code (it may have been PO730), but is says "Clutch Disc Speed Sensor". The fault code was cancelled, but the light came on again a week later. The gearbox will then only select 3 forward gears and reverse. My question is: is it likely that it is just the sensor that is faulty? When driving with the diagnostic tool connected to the car, the clutch disc speed seems to be the same as the engine speed, except when the gear is changing. If it is the sensor - where is it? Is it an external sensor which can be changed easily? Any help would be appreciated.

Hello and welcome.

Sorry it's in such sad circumstances.

This is such a common problem that we've a dedicated thread for it. I've moved this post across - please can everyone continue this discussion here.
