I've downloaded the SP Daten V45 files (thanks to OP) and extracted using WinRAR. The following folders are what I have:
From what I have read, the only folders required are sgdat, daten and ecu, what is the purpose of the remaining folders? The data folder alone has almost 10Gb of data in it!
I cannot get INPA (5.02), DIS V57 or Progman 32 to function 'fully' after following the guides (installing, re-installing etc.) and was wondering if I should be updating more folders as I'm getting errors regarding SGBD being incorrect. My car is an e90 lci.
Any help would be appreciated.
