I just got back from passing my emissions tests and have a little info that might be useful to someone. Before I had the idea of deleting all my emissions components I was already throwing code p0420. For whatever reason I ended up deleting EVAP, n249, vacuum reservoir, SAI and also coded out my rear o2 sensor. After I had everything deleted I was still having trouble setting readiness for my catalyst and EVAP. The way I was able to get all readiness set was to reflash with the stock bin file and let everything run through the tests and fail, I then flashed the modified bin file without resetting the CEL and everything immediately showed as passed with vcds and also the android torque application.


All set to "0"

For EVAP - CDTES, CDLDP
for rear 02 - CDKAT, CDKATSPF, CWDLSAHK
for SAI - MSLUB
   

I have all relays still plugged in so I don't get any MIL's. I might end up reverting some components back to factory but I haven't decided 100% which ones yet. If I wanted to remove N249, N112, N80 and P299 relays I think this would be the solution:

Factory 518ak: AA   FF   00   30   E3   F8   30
Modified:          AA   FF   00   33   E3   FB   FC

Hello ! Help me find the address USMIN ?

Been working closely with someone else from the forum on this matter for some time.

Basically setting readiness is quite easy with a little bit of custom code. 

Check in the FR for EVSUP_1.  If you would like to find it in IDA then with ME7info you will find the RAM address for readiness byte.  One byte back will be EVSUP_1 every time.  Now with this RAM address you will be able to replace the instructions for this with a call that points to your code.  In the FR you will see how to appropriately set your bits to get whatever readiness you would want.  Simply move EVSUP_1 to an open registry (in this case it would likely be rL4) and set rL4 to whatever combination you need.  I.E if you want to set every monitor to ready then you would put all 1's (11111111) or FF in hex.  With some basic understanding of asm you will in short time with 3 lines or less be able to set evsup_1 to whatever you like. 

Happy Hunting

can anyone walk me through how to find these two in my m-box so i can set them to zero? Or is there a reference guide anywhere on how to find these addresses in the hex editor?

I have a problem that's kind of the opposite of what most people are doing.  I'm finishing up an AWD conversion on a 1.8T Jetta using TT/R32 parts and there is an extra EVAP solenoid on the charcoal canister I need to get working.  All the mk1 TT quattros have this extra valve and I either have to enable it in my ECU or just buy a TT one I guess.  There's no mention of the N115 valve in the S4 wiki at all, just the N80.  Anyone know if there is another bit pair somewhere to enable/disable the N115 valve?

So that modification to ESKONF got me halfway there.  That just enabled the DTC which I was afraid of, but it does confirm that I have the right pin!  If I connect the valve to that pin it clears the codes, but it doesn't turn it on the valve during the leak test.  I found a bit called CLATEVE2 in the 06A906032DR XDF on here (at 0x10792) and tried setting that to 3 just like CLATEVE.  That also didn't work.

I guess the next step is to try a TT ECU file or something...

Edit: Tried a TT file from an AWP 8N0906018L (it was way more similar than the AL), works perfectly now!  Thanks for all the help on this forum!
