I think my 2003 Jetta has a problem with its fuel temps sensor. It always says 91 deg with the tdi timing checker, thus "engine not warm enought"...could it be related to the fact that i am in very cold weather now ? (much below freezing point). Fuel never read high, even after 1h highway drive.

I understand now that it is under the top cover of the pump...is there any write-ups for that, and where can i get such temp sensor (other than the stealer) ? most current parts store dont list such sensor...only coolant sensors.

thanks !

See dieselgeek.com He has everything you need to change the sensor, dont forget the special socket you need to remove the top cover, he has that also.
