Yes there looks to be an ECU on the wing behind the glow plug control box. I was a bit miffed when I spotted it as the whole idea of getting this van was to be electronics free after the hassle I've had with my 2016 Citroen relay! Before the Relay I had an 2002 Expert that had over 250k on it and it never missed a beat.
It definitely seems temperature related. I was thinking of changing the MAF sensor next incase this was sensing temperature as well.

Hi, new to the group so bare with me.
2004 Fiat Scudo 1.9D.
First thing in the morning when turning on the ignition l have no glow plug light and it won't start.
If I hotwire the glow plugs it will start but smokes horrendously!
If I drive it for a bit then stop and restart the glow plug light comes on and it runs like normal. If I don't start it first thing and leave it parked in the sun till midday it will probably start like normal, but not always. After the initial start it will start like normal even if left on site all day. When the glowplug light doesn't come on and I start it the temperature gauge doesn't work either.
So far I've replaced the temperature sensor and glowplug control box.
Anyone else had this problem?
