Hey,

I want to delete the SAI on my AUQ Golf (06A906032HN).
According to the wiki I've set CWKONABG, MSLUB, MSLBAS to 0 and changed the last 2 ESKONF bytes to FB and 3C (11 11 10 00 and 00 11 00 00)
As I understand the ECU now thinks A) no secondary pump and valve installed B) there is no airmass expected

therefore it should pass emissions without sai DTCs right?
Can someone with more experience tell me if it's right like that?

cheers

If your only intention is to delete the SAI;

00 11 00 00 (30) is stock value

00 11 11 00 (3C) to delete the SAI solenoid valve (n112)
CWKONABG = 1
CDSLS = 0

I don't think you need to touch MSLUB and MSLBAS when you have the hardware removed.

""However, if your SAI pump is dead or failing, it will cause cold start issues. In addition, it will only show SAI unsupported, and NOT truly passed. To fix this, unplug the pump from the relay and modify

MSLUB
MSLBAS
The values in this table are calculated airflow for a given battery voltage and are displayed in kg/h. To disable (or rather fool the ecu into accepting no flow as normal) you must set these values to 0. It will also have the happy side effect of causing the readiness tests to actually run and pass.

If you choose this method, make sure to set CDSLS and CWKONABG back to stock.

If you wish to remove the relay completely as well, you must also disable circuit diagnosis in ESKONF by setting the appropriate bitpairs SLV (N112) and SLP (J299) to 11 and possibly also set CWKONABG to 0.""

I understand I have to deal with MSLUB and MSLBAS as well as setting the SAI to not installed via ESKONF and CWKONABG.

Or will the ECU with changed ESKONF and CWKONABG not care what values are in MSLUB and MSLBAS?? In this case it wont matter if MSLUB and MSLBAS are stock or 0, right?

The method what I told you is what i've been using for SAI deletes and it doesn't give error messages. Too be honest i'm not too sure about VCDS readings, but it should read 'passed'.

So yes in theory it does not care about the values in MSLUB and MSLBAS. Try it out and see for yourself.

I chose to leave the relay in its place, but you can delete this aswell. I don't see the point in doing so. If you do edit ESKONF accordingly.

ESKONF + MSLUB is all that is needed.

Ok.

thank you guys. :)
