Post the DTC list. I think you also need to disable the DTC for the oxygen sensor heater amplifiers.

These are the DTCs:

17931 - Crash Signal from Airbag Controller: Implausible Signal
        P1523 - 35-10 - - - Intermittent
16816 - Main Catalyst: Bank 2: Efficiency Below Threshold
        P0432 - 35-00 - -
16806 - Main Catalyst: Bank 1: Efficiency Below Threshold
        P0422 - 35-00 - -
17831 - Secondary Air Injection System: Bank 1: Insufficient Flow
        P1423 - 35-00 - -
17819 - Secondary Air Injection System: Bank 2: Insufficient Flow
        P1411 - 35-00 - -

So there are people who have d@m files for every cars, and they sell them for a lot of $$?
What about the TunerPro .xdf files? I found some S4 files on Nyet's homepage. From where could he got them?
I tried to search many chiptuning forums, started threads to ask for a little help but nothing. Nobody knows nothing about this ECU, or just wouldn't like to share the info..
You guys are so helpful here (thanks for that), but now I see that without a d@m or .xdf file its hard to find the right memory blocks..
Btw I'll try every tips, maybe some of them will work so please feel free and dont stop to give tips 

I think 14A56 is where fault code area starts, here you can set 0 to ignore cel but it's difficult to tell which byte is the correct one without the dam

I'm looking for the d@m file for this ECU, can anyone point me into the right direction?, it's an Euro 1.8T
