Brilliant isn't it. Electronic only. I keep reading that folk don't trust it and now I know why!
I don't like the principle at all for a lot of reasons. We were all told for years to measure the oil cold - basic sound engineering principle - find out how much is actually in there. Not anymore. We're measuring it when its traveling and warming up.
I've not gone out and got a dipstick yet. I can't even see where it would go. Apparently there is a tube with a plastic bung clipped in it. I can't see it. Looking at other forums I've seen photos of an engine cover with a curved cut out where dip stick would go. Mine doesn't have that, I'm guessing my dipstick tube is under my engine cover. Can't say I fancy wrenching the engine cover off every time I need to double check the oil. Vorsprung Durch Whatever.
Did a bit of digging and it seems the dipstick tube is shorter than normal and is under the engine cover. Older TDI before 2010 have a hole in the engine cover and a longer dipstick tube so it's easy to buy a compatible stick and leve it fitted permanently. Less than a tenner from the dealer.
Not sure about a solution for newer engines. Seems the best option is an adjustable workshop dipstick for occasional use. Max Minimum are 488 = MAX, 512 = MIN
