Hello. I have Fiat Stilo JTD 3-doors 2002 and my parking sensors are not working. On dash there is no faults no parking sensors fault or etc. It just beeps when turn rear gear and that is all. Maybe do you know where is the problem with that?
As mentioned good clean is needed that includes the connector as well, use some contact cleaner. If possible check the car for any errors it might be thay there are some but not showing up. If no luck get ne sensors connect them and see it it will work then.
