I have a New 2022 Fiat camper van. It has the electronic dashboard display.
The van as no oil dipstick , Oil level is shown on a digital gauge, last September i noticed the gauge was showing only 2 bars. So topped up with 1l of oil . 300 miles later i had an engine warning excessive oil in engine. Only way to remove oil was via sump.
The van as been stored in my garage most of the winter. Checking it out ready use. The oil gauge still not moved . Spoke local Fiat commercial garage and booked Van in for diagnostic check, they found that the engine oil level was at 75%level and more checks showed oil sensor not working.So now awaiting delivery of new sensor.
I have heard that it is a common fault on the New model ducato.
If you have a New Model check your Oil gauge is working
