Looking for engine wiring diagram.
2011 2.2 engine
Dash Thermostat gauge issue.
Gauge has delayed movement. When engine is up to temp, gauge on sits above bottom reading.

Any advice/help welcomed.

There are several Ducato workshop manuals in the forum downloads section here: https://www.fiatforum.com/downloads.php?categoryid=22

You may need to try more than one of them to get the correct one for your vehicle.

Many thanks. I’ll look through them.

Orville you probably have the ford puma engine in yours. I had a ducato 2.2 100hp in a burstner and it developed the opposite issue to yours in that the guage launched itself to max on start up which caused it to shut off. Disconnecting the cylinder head temp sender made the ecu think it was cold all the time but would let it run. Replacement of the sender was the cure, but it was a total arse to replace.
If you know a bit about electronics then you can test your guage by jumping the sensor connector with a 1k ohm variable resistor with different settings.
