Think the diesel gelled, possible to reliquify?

I looked around the other posts, but could find anything about getting the diesel to reliquify other than putting the Treg in the garage.

So the symptoms: cranks strong, starts in the beginning for 3-4 seconds--dies. After that cranks, starts and dies within a second or two.

Temperatures here the night before the problem dropped to -10 the wind chill.

Makes a whining noise in between.

So, my question is if I can wrap the fuel pump with a heating pad and put a small space heater somewhere to heat something to get her started.

Im trying to back the Treg into the garage.

Ive read everything about the emergency additives, but im not comfortable taking apart the fuel pump.


Thoughts?

Put some power service diesel 911 red bottle in the tank. The other option is place a halogen work light underneath by the fuel lines and also one to warm up under the hood fuel lines. For in the future keep the tank full of diesel and add some anti gelling additive. Also use the additive if you filled up in a warmer region before heading into a cold region.
In the past I've heard of people adding gasoline to the diesel but that was before common rail.
Those old diesels would run on nearly anything.
I don't know what proportion to use.
DO NOT ---- I REPEAT ---- DO NOT MIX GASOLINE IN THE FUEL OF THESE ENGINES!!!

Your fuel pump already contains a heating element. Diesel 911 is a good idea. The halogen shop light is also a good idea.
I get nervous advising anything to this OP for he does not even list a diesel in his sig. His username is 2011VR6NJ. That there does not signify he even has a diesel.
Wind chill means nothing.
What was the REAL temp?
Where did you get fuels last?

I had my MB CDI gel, but I bought a tank of fuel well south of where I live and temps hit -14 (actual).
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.
My work van Freightliner Sprinter so MB inline 5 diesel . I had that gel up several years ago -bitter cold hit unexpectedly and if your fuel pump is making a whining sound, I bet your fuel gelled. Ever since , with the Sprinter I use anti-gel power service all winter.( sits outside).
Touareg is in the heated garage so not often with that.
I've heard some station have some kind of anti-gel added already in their diesel.
As mentioned above, get some Power Service 911 to add to your tank:

Diesel 9•1•1 | Power Service

Also, will temps in your region be warming anytime soon? That will definitely help your cause, as the gelling should begin to subside with above freezing temps.

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.

We hit -20° in VT Friday night into Saturday AM. My T2, with a full tank and additive, would not start. Needed a jump. This is a one year old battery showing 14+ amps. Could it be more of a lack of compression issue than gelling?

Side note, driving home through every varity of Mother Natures muck and mire (and Suburbans on "all season" tires) that could be (and was) thrown at us last night truly demonstrates the prowess of the Touareg on full snows...
...showing 14+ amps.
Do you mean 14+ volts, and if so, while cranking? Starter draw is going to be closer to 100+ amps than 14. Voltage should be 12+ but will drop when cranking and should rise to 14+ while the engine is running and recharging.
Are you trying to start the vehicle before the glow plug light goes off?

Right, thanks volts...

Yes, tried with push button start and separately with the key turn on before cranking.

I'm with Yeti. First thing I noticed. Guy clearly lists VR6.....

As for fuel gelling, I've had diesel gel on my before (never in a Touareg though). My experience was always a lot of whiteish smoky exhaust and a stumbly / bumbly idle. That was before DPF's though. Back then (this was a 1980 Dasher Diesel), a little kerosene in the fuel tank and it was good to go. Now - I don't think I'd do that to a Touareg.

I hope I never have to deal with it. Made it through a couple of really cold nights so far this winter (-15F or so) and fired up fine.

But to the OP - I'd make sure you have a TDI.
