It appears ECS & others have made a clear distinction that TSI parts are NOT compatible with TFSI cars. We all know that isn’t always the case. Which brings me to these intake manifolds. On the one hand, you have those designated for TSI applications (A3, Q3, VW CC, EOS, etc). The most updated version pictured below clearly states that it won’t fit with a B8 A4, both fwd & Quattro. To add insult to injury, it’s listed at only $175??!!
On the other hand, when searched under my correct B8 A4 2.0t Quattro, here’s my option(s)..
And can someone explain to me how is it that the version designated for our cars cost nearly 3 times as much!! This is akin to highway robbery!!
Anyways, you get my drift. So, if any of you wish to shed some light here by outlining similarities & differences as well as comparability, I’M ALL EARS!

I have very similar problem, but with worse price difference. I am tired of it and want opinions.
I live in EU and have a 1.8TFSI A4 B8 2009 non-quattro. The 1.8 TFSI (mine is CDHB) is basically a spec-ed down version of the 2.0TFSI that you guys have in USA. So 1 year ago I got the Implausible signal error from the position sensor and bad fuel Trim error (because of vacuum leak) at the same time. I visited several diagnostic places plus the dealership and all said - broken intake manifold. They all showed me the Humble Mechanic video, there it is leaking around the flaps control lever. The dealership price was (converted to USD) ~900 dollars for manifold and work. They sell the entire KIT only. I decided to check by myself and the help of a friend mechanic. We disassembled the manifold and saw that it has a different lever than the one suspected for leaking (in the humble mechanic video is black mine is white). There was no play and no air leak. The manifold seemed pretty clean from oil and stuff, we cleaned it. We removed the sensor and saw that the green plastic thing with the rectangular hole for the flaps shaft is worn and decided to replace the sensor (with one new from ebay that had the audi logo and appeared that is for my car and a lot other models), so that there is no play on the sensor end. So we did that and AFAIRemeber the error disappeared but the vacuum leak error stayed. So after another long story it appeared that the vacuum leak is from the PCV. Changed the PCV and the vacuum leak error was gone and the MIL too.
But after some time I noticed that when cold-started (was winter here) there is a slight roughness in the car and goes away after a minute. So I did a diagnostic and a new Flap Position sensor error was there - Stuck Open. So we knew the drill- removed the manifold bough a new cheaper sensor with the same number but no Audi logo (from amazon) and replaced it again. No change the error was still there. We disassembled everything again and started moving the flaps manually while monitoring the sensor readings with VAS. the flaps were moving 0-100% while the readings 43-82%. We decided to remove the sensor and see if there is a play in the rectangular hole- there wasn't. We moved the sensor manually (not the flaps) and the readings in VAS were 0-100%. Then we noticed that the sensor has about >90 degrees of travel, while the flaps shaft and the flaps have ~45 degrees of travel by design. So we decided that either the sensor had to be adapted or we got a wrong sensor both times. Unfortunately, we threw the original sensor away and I cannot compare the last letters behind the number. We might got those wrong, maybe the sensor is for the updated manifold. We found intake position flaps adaptation prompt in VAS for this sensor but it just doesn't work. It reads the Required 0% Real 42% values and says that it cannot continue. I asked the dealership and they said that there is no such adaptation- you have to replace everything. I am very skeptical that such small thing should require entire manifold. So as I live in EU some parts have different numbers and I cannot find aftermarket manifold with the same number as mine, anywhere. The dealership don't give me their numbers, but even if they did their number is for the KIT.
The manifold looks just as the one you have on the photo and as the one all US A4 B8 TFSI ones have. I have a way to get one from USA and pay some import fees and still will be a lot cheaper than 700$ here.
Could someone share some thoughts? I can later provide pictures and numbers. There is a video I made about the travel difference

Can you share your 2.0TFSI manifold and sensor part numbers? I really want to risk with the 174$ TSI version, that is available everywhere in USA, just because I hate how the dealership is robbing us. According to my mechanic 2.0 and 1.8tfsi versions have the same design but different codes and part numbers.
as well as the car running too lean.
