I live in MN. I just bought a 2016 A6 TDI. It seems like every gas station has different signage around their diesel fuel.
1. Blue sticker that says "Biodiesel blend - may contain between 5-20% biodiesel"
2. Blue sticker that says "Biodiesel" and the handle of the pump says biodiesel. Do I assume this is 100% biodiesel?

I don't think there is any "regular" diesel around me.

Am I OK using the biodiesel blend? Is there even any other kind available in MN?

Here is the official MN web page on diesel. https://mn.gov/commerce/industries/fuel/biodiesel/ MN mandates 20% biodiesel so you won't find pure dino diesel unless you fill with No. 1 diesel, at least until next year when they mandate bio blends in that as well. Audi says no more than 10% bio, but will cover warranty issues in states that mandate higher percentages so no worries there. I would not expect anyplace to be 100% bio unless home made, but cannot state that with certainty. Where in MN are you? Fleet Farm and KwikTrip usually have decent diesel. I haven't had issues with fuel when visiting family. I am sure it is heretical but I almost always use No. 2 and have not noticed any issues even in winter at -20.

I'm by White Bear Lake so plenty of Kwik Trip and Fleet Farm options. Thank you for your reply.

I'm actually kind of regretting the TDI purchase, but I'll live with it

Yes, it will be very very tough on you, all that torque on the freeway and filling up every 3 weeks instead of weekly...downright brutal! Welcome to the club
