SAI (Secondary Air Intake) bypass with APR software

[noone]

Ladies and Gents with APR tuned 9N3 GTI's.

I had asked Guy from APR to look into the coding of the SAI codes encountered by some when bypassing the SAI system. For whatever reason, this issue appears to be more prevelant on APR tuned cars than some other softwares. This is to say, that using the blanking plates, resistors, etc does not make the code go away, and the light on the dash is not doing any damage, but prevents indication of a real issue (and is unsightly).

Guy has been kind enough to delegate some resources to this matter and has advised he will be offering a SAI bypass version of the tune in the near future (technically available now, but it is yet to be distributed as APR does in batches I assume).

At this time the cost has been advised as $250, which given the work required to code out and I believe APR will stand behind the coding and support their software and that the dealers uploading the code require a piece of the action, seems reasonable to me.

Regardless of the costs or how many people go down this path, I'd like to thank Guy for looking into this for us.

I've chosen not to add this to an existing thread as I think it would get lost in amongst the conversation for future Polo enthusiasts.

Feedback / comments / interest welcome.

Thanks Noone,and thanks Guy...good to see dev work still being done on the 9n's

im still confused as to why its only some which are affected and not all?

We all are, across the globe...

For what it's worth, this worked for me, and may be worth a try on problem cars (ie, it's cheap). The original 300ohm air pump resistor from IE resulted in a code. So upped resistance to 400ohm, got a code part of the time. Upped again to 470ohm, and now no code for many weeks/kms. Touch wood.

Cheers.

Yeah, I've been without the code for weeks, kms, seems to come back sooner or later.

I have the code pop up and will be first in line when this comes out. Feel free to take my money!

Still code free 30,000ks it's all about the resistance

I just dont see it. Has anyone with APR software been able to get around the code?
Has anyone with CC had ongoing issues with the code.

Something in the code me thinks, happy to have another go as its just a few resistors, but I don't see this being the solution for all Polos.

I played a bit with resistors, and the CEL still came on...it my also have something to do with the ecu codes ? I'm also getting a CC code soon, so will let you know post that.
