Default IPD HD CBV spring replacement

There already was a spring in the CBV but how can I get it out to replace it with a heavier spring? There are 3 options so im assuming its changeable.
Help is much appreciated

Just remove the CBV - 3 bolts. The spring is inside the CBV pushing the diaphragm against the turbo. Is there something that I'm missing from your question?

He removes the the CBV in this video, the spring is inside the cover he is taking off.

Thanks for your reply.

Maybe I should be more specific: Indeed it's easy to take off the metal cap from the turbo but that's not the issue. The IPD set comes with 3 springs which you can install between two plastic parts that click into each other. Mine already had a spring installed from the manufacturer which I want to replace by the blue (heavier) spring. I can't find anywhere how you can detach the two plastic parts to change the springs.

Does anybody have an idea?

Ah, now I get it.

Here are IPD's installation from their website if it helps: https://www.ipdusa.com/files/product...LL%20GUIDE.PDF

Looks like the 2 parts just snap together? Maybe someone has the item and can chime in here.

Can't they just be gently pulled apart?

Tried that for about 2 hours, until I was seriously worried breaking it. Anybody any experience?

That was my experience with the kit provided for P80 cars. Maybe I also used pliars to squeeze the little tabs a bit.

Default Hey I got the same kit, and same prob!

It's actually pretty easy to separate, I poked some tweezers inside the hole and squeezed the center plastic pin while wiggling.
I guess that would be obvious if you were the one who clipped it together :<
