No idea to be honest. I had Carista module anyway and only used it on my previous Skoda which has been replaced by the van. Used it last year to tweak some settings on the Fabia and not used since (they did give me beta version that time as well after I contacted them regarding some settings, beta lasted for one month, and then reverted back to paid version). This time I plugged the module in my new van and it required me to send a new vehicle report and all beta tweaks are here, don't know for how long tho. I managed to tweak folding mirrors on lock (single click, no need to hold lock button like if you are closing the windows), also it gives an option of Skandinavian DRLs ( rear lights and dash lights on with front DRLs). Gave me a reading of DPF status and option to initiate DPF regeneration if required (didn't used it), reading showed DPF status 29% and the same day van did its own DPF regeneration on the way home and I took a reading out of interest and it was 8%. I remember when I had first time beta, I emailed Carista, and I also know some other members of Skoda forum also got given beta for a month after they emailed Carista support. Worth a try and test some tweaks and provide feedback to them.
