i have a 1999 jetta tdi
it is getting hard to started now that it is starting to get cool out. i checked my glow plugs and they at not coming on. so i checked the fuse and the relay. they are good. so i put a new coolant sensor in but it still is hard to start. so i unplugged the coolant sensor. the glow plugs turned on for 20 sec. the car started right up. what do i do now
