Vw MK4 Bora 1.9 TDI ALH ticking sound

Hello everyone,

I have a problem with my Bora MK4 1.9 TDI. The problem is a ticking sound coming from the engine bay. The ticking intensify with rpm . It is present both when the vehicle is not moving or moving.

The timing belt with all pulley ,serpentine belt has been changed 3 months ago.
I changed the dual-mass flywheel with the clutch 1 month ago.
Oil was changed with all filters 3 months ago.

Here are some video with the sound :

In the second video i put a microphone in engine bay and i go for a ride.
The ticking noise is present all the time but at 2:46 when the car at low rpm is cleary and at high rpm at 3:05

I went today at the local service which changed my timing belt and they said that this ticking noise didnt came from timing/serpentine belt.

What could be the problem?

It sounds to me like the valves need adjustment.
