Ok, I performed a search on the subject and found a few posts regarding deleting the SAI. Unfortunately none are specific to our R32. The closest, was a 2.8 VR6 DYI.
What does it do? It is used to lower emissions especially during cold start up. Allow the Catalytic converters to warm up faster.
1. aesthetics, cleaner engine bay
2. more room to work on engine
3. less weight (avg. system including pump, hoses, and switches aprox. 7 lbs.)
2. not passing state inspections
Has anyone any input?
I was thinking of questioning Jeff at United Motorsports to see if he could override the fault(s)/readiness code.
Has anyone done this on a NA motor?
PSU, have you done this?
I read the 1.8T versionm the resistor at the air pump plug, according to the author, only prevents the CEL for a missing SAI pump missing. The delete will prompt a improper flow CEL, that the author didn't provide a remedy. The author still has 2 CEL faults due to the SAI improper flow, and PCV delete.
Were you able to do so without faults??

Just red the "IE 24V SAI Block Off Plates In Stock and On Sale!" post on the MK4 R forum. I initially didn't read the whole thing, thinking it was only regarding the selling the block off plate. There is actual good information. Apparently some of the UM tunes already have the SAI disabled. I suppose I could test mine by unplugging and seeing if it throws any codes.
Now I don't know if there is anything different or specific on the Mk5 R?
Just have UM flash the car and they can stop the CEL from coming on.
I used an IE MK4 R32 SAI delete kit and then made my own block off for the passanger side combi valve to the head. I am working with pete at IE to make a plate for that too so expect them to offer complete kits in the near future.

So, removed the SAI. I chose not to use the resistor in the plug, so CEL is on. I have an appointment with Jeff at UM coming soon to sort this out. Not much in weight savings, maybe 10-15lbs. Car runs smooth as always. Engine bay looks slightly less congested.
Any weight saved (especially from the front) is great!
I'm interested in this as I am contemplating an HPA 20th and this subject came up here:
HPA tells me there will be no codes / issues with passing emissions with their ECU tune for their kit, so apparently it must be tune-able-out-able.
I am thinking about doing this. I have the UM tune does anyone know what it cost to get UM to remove the CEL? or is it free, and you just need to contact UM? I should probably just contact UM anyways lol
