Truck was probably doing a regen of the DPF. Mine sounds the same way if itís doing a regen and I turn the truck off.

After shut-down, my '16 sounds like R2D2 is under the hood...and mad about it.

All kinds of clicking and servo noises.

On my third DMax.

When my 2019 is doing a regen the rpm's will be just above 750 when it is normally around 600'ish when stopped at a light or in the driveway. If you get out of your truck the exhaust will be hot as hell and blowing harder too.
