Not sure what the build week is for mine. It was from stock at the dealers and I collected it on November 19th. There’s a post on another forum suggesting that the software number relates to the infotainment system only. Mine had a blackout, but since the last trip to the dealers it’s been fine. It has been said that the problems occurring with the assist systems stem from the steering wheel and associated wiring and that in some cases a new wheel is required. I’ll just keep taking mine back to the garage until finally fixed and hope that VW will see the cost of warranty claims keep rising and perhaps address the various problems rather than leaving it up to individual dealers to muddle through. Love the car, hate the technology!
