lets see if I can help.
P0380 code sets if the relay is malfunctioning or if the fuse for the glow plug blows if this code does not return right away after it is cleared then I would suspect the relay malfunctioning intermittently. if you have the VIN # XXXXX can find the location of the relay for you
it is a vw Jetta TDI 1997 Vin # XXXXX
If it is a relay then why does it work fine? Can I drive it and reset the check engine light with a bad relay? Is the relay part # XXXXX ?
Thanks in advance.
glow plug relay may not be making correct contact at times this may be why it seems to be operating correctly this code is set when the ecm does not see the correct signal from the control unit.
it is located under the dash on the fuse relay panel location #12 should have a production # XXXXX the top of the relay of 102 0r 104 the part # XXXXX listed is the glow plug control module .note I have seen them also locate this under the hood. near the cowl.
