Hi, distributor is a common problem on the Uno. Replaced mine in March this year bought the unit from a spares dealer - non Fiat part. Works fine now. Sadly you can expect it to go since it's close to the engine and the module heats up. In the 5 years I've owned mine I did the module 3 times and complete unit once. Check if it's not only the module before doing the complete unit. Good luck.
