If you drive Touareg TDI while having 2011VR6NJ nick name on the CT…

Gelled diesel happens with summer diesel (#2) when REAL air temperature readings fall down to somewhere around 17F. Keep in mind that bio-diesels have higher gelling temps than pure petrol diesels. (Properly mixed winterized or winter-blended diesels bought in Minnesota are advertised safe to operate with temps as low as -30F. I use Power Service white bottle additive as soon as temps hit 10F mark – simply because fuel-related surprises are not on my fun list.) Check your local rules/regulations on diesel winter treatment.

Recalling from my RTFM times, Touareg TDI (T3) can use #2 diesel with temps as low as 10F. As most modern diesel vehicles - Touareg TDI is equipped with heating elements installed @ critical points of fuel delivery system (fuel filter is one of them). If your vehicle experienced air temperatures below 10F - diesel gelling might be the case. As suggested by others: use the red bottle Power Service 911 according to instructions.

Good luck!

I had a 2010 VW Sportwagen TDI that was out in below zero temps several times ---- never had a start/gelling issue. Should be the same for the Touareg.

Agree. I had a number of occasions starting vehicle with -20F outside with no problem (no additives). But in MN, as everywhere else in Mid-West, diesel sold from mid-October is winterized or blended for winter. I gather OP is from somewhere on the East Cost, where things are different. With white bottle Power Service Touareg starts reliably in -30F. Couple of times started successfully in -40F when I was ice-fishing in Ontario.
p.S. I keep jump-start unit with me when travel far and /or in wilderness.
