Apparently the idea is not allowed in the Touareg world that there is an aftermarket out there to support... well, whatever. If there is a decent set of mud flaps for a 2011, it stands to reason that there would be a set for a 2020 - maybe. It is new, so the aftermarket can take a bit to get new models unless it is the same as the last one and they already have a product for the previous year's model.
I probably shouldn't mention that I have an aftermarket set on my 2010, because by God, it is a T2. The horror! I paid $21 for a set of 4 from Amazon. They only needed a slight bit of massaging to get them to fit in the original fender liner holes.
Sorry, I don't buy into the thought that I MUST buy items that cost several hundred dollars because the vehicle originally cost $50K +. I didn't pay $50K for it - I paid $10K. I don't need $200 apiece tires because the vehicle cost $50K new. IDGAF what it cost new. To me, it is a very nice $10K vehicle. I'll make the same decisions on buying aftermarket products or tires or wiper blades or floor mats or whatever that I do with every other vehicle I have now or have owned in the past: Does it do the job? Is it safe? Is OEM the only thing available?
And since a pic and link seems mandatory, here is the only shot I have that you can see the mud flaps in. They are $35/set now on Amazon.

And don't even ask about the cross bars or cargo basket! LOL
