2003 Volkswagen TDI 4 cyl Front Wheel Drive Manual 90000 miles

Two days ago the engine light starting coming on about one minute after I started up the car and remaining on the whole time the car was running. There were no strange noises and the car is driving fine. I took it to Autozone and they ran a diagnostic on it and go the code " P0670" which their computer said had to do with the glow plug control module and that it the probably cause was " poor electrical connection" or to " check control module for glow plug triggering.&Quot; I called the VW dealer and he said as long as the engine light wasn't blinking, it wasn't a dire emergency which was good because I don't have the time to take my car there and be carless for days. Do you have any suggestions on ways I could check the electrical connections because maybe that's all it is.
Thank you

Most likely is a glow plug that is burned out, if that is the case it will get harder to start as time goes on,
