My girlfriend has added a jetta tdi to the household fleet. I don't know anything about diesels.

After having this thing parked at the airport for the past four day it appears the fuel has gelled (plenty of crank, but it won't turn over).

So my question is is this something that will resolved itself once the weather warms up, or is there going to need to be a repair to any part of the fuel system? Do these diesel 911 type products work? Are they harmful to the fuel system?

thanks for the input
