[Vwdiesel] Burned out glow plugs

Injectors had new nozzles put in and pressure tested at about 2000 miles.  I
guess we are going to see if the relay is cycling during the running of the
engine.  I just can't figure out how all four could burn out like that but I
suppose, since I am not driving it on a regular basis, that my son could
have been having problems all along with slow starts as one plug and then
another burned out but this being Texas and a low temp in the summer is
mid70's to high 80's, he probably didn't notice.  Hayden
