Some news !  

I extracted my original flash file from my ECU (using kess so not the full read).
I used Me7Info to see the definitions (idk exactly what i should call them) and begin to work on a automated script to add the DSG-Farts-Spark-Cut

I'm really surprised, i cannot find definitions for b_zwget neither b_gsch  

HWNumber          = {0261208088}
SWNumber          = {1037369383}
PartNumber        = {022906032CB }
SWVersion         = {5604}
EngineId          = {MOTRONIC ME7.1.}

If someone want to check the .ecu file see attached

To achieve what I want to do, I need to find the address where b_zwget will be stored at runtime. Using ME7info.exe I thought it was going to be easy (not at all  ), I have neither the b_zwget variable nor B_GSCH so I can't write my function because I won't be able to “tell the ECU” what to do when b_zwget starts populating because I don't know where it is.

I've tried to find .kp, .a2l, damos and others but I can't find any that answer my question, the only thing I've found is a golf 5 R32 damos that I pull out of I don't know where  (but which shares the same PartNumber = {022906032CB } as my car)
and which tells me when I open it via WinOLS in the RAM folder that B_ZWGET is at address FDAA and B_GSCH is at F062C.

The “problem” is that I'm not 100% sure of the info because even if the flags are at the same address between winols & the .ecu there are some differences...

From now on, what I'm going to do is directly log the car and look for the address of this damned “b_zwget”, unless someone has the answer to my question and can provide me with the address, but in the meantime I'm going to work on it solo and keep on searching the forum for info because I won't have the car to hand for a few days.

I'm writing this just for the record...

Look at the FR where it's used, find other variable located by ME7Info that is used "close" by tracing this variable you will find your bitfield.

Post that A2L you have Then I can find what you are looking for in your file

and
I think B_zwget is FDAA.7

So you advise me to not bother using b_zwget and directly check migs_w?
