Hi,
Does anyone have an idea why when warm the 2.5 diesel rpm doesn´t like to fall down as quick as when cold.
When cold: https://www.youtube.com/watch?v=YIlDrfz79E0
When hot:https://www.youtube.com/watch?v=v1qjaT2xaRw

It idles fine and starts fine when cold. When hot it takes a bit longer to start. Does not have any stutters also.
Might be some sensor that works fine when cold and fails when in operating temperature?
Might be fuel injection pump?

There is a slow drop on both of mine which is how it's supposed to be I think, but it depends how slow. I can't view your vids on my computer.

Mine takes about 4-5(sometimes longer) seconds to drop down from 2000rpm. I do not think this is normal as it does this sometimes. I just had a 2 week break from that issue and now its back.

That's a bit slow

I suggest you put it on diagnostics. Wammers would know but I'd guess the fuel quantity servo in the FIP is playing up.
