06 Jetta gelling?

[realsteel23]

So I just bought my 06 jetta. It's been -5 degrees or so here for a week. I put hot shots anti gell in it. The same stuff I use in my truck never had an issue. But tonight I was driving the jetta and all of a sudden it started shuttering I thought the dsg went out. Then the glow plug light started flashing. No CEL the car shifts fine but if you gave it fuel it'd shutter. So I limped it back to town. The light went out and ran fine. Was the fuel gelling up?

Could be the fuel filter needs replaced. But a code reader would tell you what code came on.

Look for a boost leak. I can trouble shoot if you want more info.

I noticed the butterfly on the egr is leaking. Besides that I couldn't find a boost leak.

OBD works, start there.

Yes the OBD works I checked it with my edge monitor. I dont have a ross tech cable yet......But the fuel filter has solved the issue

The fuel filter could have been icing up due to water from condensation in the fuel and not actually gelling. Glad you got it fixed. -5F temps are cold enough for icing due to water but still too warm for gelling, assuming the fuel is properly winterized and/or the anti-gel additive took care of any gelling. Even with properly winterized fuel, icing due to water from condensation can get you in trouble long before gelling will.

Avoid water in diesel fuel at ALL costs. Avoiding water in diesel fuel is more important during winter months in cold areas due to condensation being more of a problem. Fuel up ONLY at high turnover stations along major routes that get lots of heavy truck traffic. Go where the big rigs go to fuel up. Also regularly use an additive to take care of any water you can't avoid getting.
