    Thread: SAI delete??

    1. 05-09-2012 10:52 PM #1
      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.

      Why delete?
      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.)

      Issues?
      1. CEL
      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 remember doing this on my 1.8t. Fairly simple you can buy diodes to bypass the CEL. Try searching in the 1.8t technical forum

      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??

      When I performed the the SAI delete, i used two resistors one for each wire if I remember correctly. I didnt not have any CEl on the dash, but im not sure if i had hidden CEL that didnt show up on the dash but did when you scanned it

      incorrect flow... classic VR6.
      insert cheap credibility statement here...

      So Josh, powerdubs replied and confirmed that Jeff from UM should be able to delete the faults. I am now awaiting to hear from Jeff to see if and when he could do this.

      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.

      Thanks for sharing! This is definitely on my list to do.
      Looks cleaner!

      Ordered my SAI block off plate today. Hopefully make this happen in a week or so.

      United confirmed that they would be able to sort out the CEL/ faults. Sweet!
      Also ordered gasket to remove combi valve from the other side of the head. I'm hoping that my friend will be able to make a block off plate. Can't wait to clean that stuff out!

      you just need to make something simple like this until IE releases a pretty one.

      Yuup, thanks! My friend has access to a cnc machine, so it may actually be a nice piece? We will see. Thanks again.

      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:

      http://forums.vwvortex.com/showthrea...highlight=20th

      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

      Its a separate option for the SAI Delete... I think I paid $50.00 additional to the ECU Tune.
