How to detect whether already 48V-Mildhybrid or still “old” model

Hello, I ordered my ProCeed with the 136hp diesel engine in January 2020, as my previous leasing contract expires in September. If someone now asks themselves “Why so early?” I have already experienced bad surprises with the delivery times at other manufacturers. Looking back it was probably also right this time because of the Corona chaos. The vehicle was produced in June 2020 and is already standing at my dealer. Now the diesel engineization was changed at the end of April. The 48V-Mildhybrid-Technik. Now the interesting question arises for me, whether my car has already been produced as a Mildhybrid or not. How do I then recognize when I take over the vehicle, whether it is a Mildhybrid or not? Is there a hint in the papers or somewhere a “48V” print in the vehicle (please don’t laugh)? Ohso, just for a moment to clarify: I am aware that I have no claim to the Mildhybrid-Version. eug ordered, this variant did not exist yet, especially since the vehicles have become even more expensive by the Mildhybrid technology. Is just an interesting question, what happens when the technology changes after ordering but before production. Best regards
