Engine judder between 1500 - 2000 rpm

Car is a 2013 Hyundai IX35 1.7 diesel with -88k miles.

Between 1500-2000 rpm, the cars judders/kangaroo's if you are not accelerating but maintaining a constant speed/rpm. There is no issue before 1500 or after 2000 rpm or while accelerating normally or at motorway speeds. Car is likely needing a new clutch soon, but not I'm sure if that is a symptom of the judder issue?

Just curious of people thoughts or suggestions to check out, before I give up and take it to a dealer.

Thanks for reading.
