Good Used Parts Sources & Replacing Individual Intake Manifo

[RiftCygnus]

Hi everyone. I posted a while ago asking about an issue with my drivers side intake manifold runner flaps on my 2011 Audi A6 3.0T just randomly deciding to go crazy after driving a while. And it's not always consistent, as in it'll happen a few drives in a row, disappear for a few weeks or a month, then come back randomly.
I had a P2019 code two to three months ago accompany the symptoms, but it has since gone away without me clearing codes and hasn't come back since. Even though the symptoms are still present.

I had it sent to a Euro car shop and they tried driving it for a few days and found nothing. They checked for codes and found nothing, and also checked the sensor data for the intake manifold and found no abnormalities. So whatever this is, it's very finnicky and only comes out at certain times.

So what i'm thinking of doing is just ordering the parts i think may be causing the problem and have the shop replace them. But before I do that, I wanted to ask some questions.

My first question is, is it possible to replace the parts like the lower intake manifold runners' position sensor and vacuum actuator individually without having to take the turbocharger off and swap the entire lower intake manifold?

For the second question, i'll preface that i'd probably buy the sensor and actuator brand new OEM, as i'm sure it'll be a lot less expensive than an entire OEM lower intake manifold assembly. But IF I decide to put in another lower intake manifold assembly if the sensor and actuator can't be replaced individually without taking off the turbocharger, where would be a good source to buy a good quality intake manifold assembly?
From what I checked, an OEM lower intake assembly is around $1k. And from what it looks like on Amazon and such, aftermarket versions of the assembly are reviewed as and look kind of junky. So my thought is to possibly go for a used one from a low mileage vehicle from a reputable Audi salvage yard/recycler.
Does anybody know if there are possibly any good quality aftermarket intake manifold assemblies or reputable Audi salvage yards/recyclers?

Hi try eBay in Europe the Germans seem to have a plentiful supply of low milage used parts.

Don't be surprised if you get very few replies. We are not ignoring you, however most members are British and have no knowledge of American parts suppliers and car breakers (aka recyclers).

Cool man. Thanks for the heads up on that. I'll check it out.

It's not a problem. I figured that was the case, but even just getting input on the ability to replace individual parts on the lower intake manifold is helpful. Any kind of input is helpful, so i'm just throwing it all out there.
