@vw019283 and
@2018gti : Hi to you both!!
First about "flash files" and "Datasets" and "parameters". My understanding is that these are ALL names used by different folk for the same thing.
The basic concept for these modules is like this: At the highest level of discussion - we are talking about vehicles that have a MQB platform build. So, the VAG group (being the parent company for the monolithic conglomerate that sells these cars) uses this platform across a wide range of car brands like Audi, VW, Seat etc. This means that the same module is often suitable for many car brands notwithstanding that to operate correctly on a particular model, the module software needs to be tailored to the brand, model and build year.
The way that VAG minimizes costs across the various brands/models is with "Dataset/Parameter-files/Flash-files"- meaning that the module will often have the same Part Number and Software Number (think about the module software as being the fundamental module firmware) across different brands/models/build-years - but the Dataset will be different to meet the requirements of a particular make/model/build-year - hope this makes sense.
Of course, my description above is a very general summary and some times the final digits in the Part Number and Software number are also important considerations as to the suitability of a retrofitted module
OK -
@vw019283: With no offense intended, not ALL mk7 GTE's were built the same over the many years of production. Importantly for this project, a major change happened to mk7s in about the middle of 2016 - the 09 module was radically re-programmed and the entire module database was changed. One of these important changes resulted in the deletion of the long-code string that existed in the earlier version 09 module. In later model 09 modules, ALL of the long-code software switches (i.e. the Bits in the numerous Bytes) were transferred to the database for the adaptation channels. A consequence of the deletion of long-code from these later modules is that most diagnostic devices either report a zero-string, or no long-code entry at all.
I'm not sure - but my strong suspicion is that the 09 module instructions that you posted refer to the newer module without an active long-code string.
Does a SCAN of the existing 09 module in this car report an active long-code? If so, this is likely the reason for your 09 module difficulties and it's also the likely reason for some of the consequential error messages in the other modules (because the AFS settings in the 09 module are not correct)
Again, my words above are predicated on my limited understanding of information provided about these two similar, but very different projects - so I could be wrong!
