Hey guy's. I have a question.
My Hyundai 2013 66 kw CRDI sometimes start's trembling on idle.
Usually after some time then engine start's getting worm.
RPM goes down to 700~.

Maybe someone had the same problem.
Thanks a lot.

Check handbook re idle rpm and compare to actual.

when it happens have you tried to increase rpm slightly by pressing gas pedal?

If so, does it smooth out and at what rpm?
Is that rpm as stated in handbook?

If yes then i would say idle speed requires altering.

If not tried, try it and see if it makes a change.

Unclear!
Does the tremble occur when cold?
Does tremble disappear when warm?
What RPM on hot motor?
How many Kms has the car done?

At cold start RPM settles at 900 and it has no tremble.
When worm/hot sometimes it stays at 900 and sometimes it goes down to 700.
And then it goes to 700 it start to tremble, no problem at 900.
Car has 140k km

Normal Warm to Hot RPM is 680-700 rpm from memory.
High revs when hot could indicate an air leak.
the roughness or trembling as you call it could be anything from fuel air mix to an injector .
Have you scanned for error codes?
Cleaned EGR and MAF ?
Check vacuum lines for cracks.
Check throttle position sensor
