Light on dashboard, Fiat Ducato

Check your Fiat handbook. The warning symbols are shown in there. 

It’s probably the 2 year service reminder based on the length of time since your Fiat was manufactured. Don’t ignore it but contact your Fiat Professional garage.

The sensor on the Ducato indicating oil level is notoriously prone to failure. Get the Fiat dealer to run a diagnostic check and if it’s faulty get it done asap under warranty as it’s an expensive fix - cheap part, but big labour costs. 

Just out of interest our (Mercedes) oil light comes on when it's been overfilled at a service etc. We've stopped worrying about it now, it could be something simple like this but check it out first.

Hi all,

Thanks to Tinwheeler, already done that can't find it anywhere.  And SeasideBill and Brue, it's definitely not the oil warning light, that's a red warning symbol lower down on the dash.

I'm going with my original theory that it's to do with some sort of service due indicator, even though it isn't due yet, but who knows when that might have been originally set?

Thanks for your replies.

Best wishes.

The service due on most vehicles is a spanner logo it was on our boxer , same stable

You could be right as your van is 2 years old and the first service must be imminent. However, there’s a good chance it's a warning of low oil pressure or something equally important and you may find the engine will go into limp mode if you ignore it. I’d get it checked by your Fiat garage or, if you can’t get there, call Fiat Camper Assist who will send out an RAC man with a diagnostic kit.

I believe this particular symbol depicts an engine oil warning light sensor malfunction.   Try Googling Ducato dash panel warning lights for confirmation (or otherwise).

It’s not a service indicator. See page 70 of the Ducato Handbook 2019-07 (download available) and you’ll see your warning light listed. It’s the usual suspect - ENGINE OIL LEVEL WARNING LIGHT SENSOR FAILURE. Sometimes exactly the same problem triggers the amber generic warning light instead. I know more people than I should with the exact same problem. Insist on replacements under warranty and keep your finger crossed the replacement is more reliable. The ECU fault log will confirm the sensor is at fault. Unfortunately a lot of stuff needs to be dismantled to replace sensor, so expensive fix! You won’t go into limp mode.

Hi Tim

Did you get any progress on this? My 2019 150 engine has done the same, now out of warranty, just took to Fiat and they want £860 to replace the sensor. I will try and get Fiat to do as a gesture of goodwill as the fault has occurred intermittently, the van is 3 month out of warranty and only done 8K miles due to covid. Your experience with this fault would be interesting to note. Thanks 

This fault is common, Fiat have replaced some sensors under warranty but it’s down to goodwill if that doesn’t apply.  I think you could argue that Covid ‘down time’ is a factor here and your warranty should therefore be extended as the fault would otherwise have been apparent in normal use. Good luck.
