Order of inspection
P0682 Glow Plug 12 Circuit Low
The P0682 code means the glow plug for cylinder 12, or its circuit, is not working the way the computer expects. A diesel with this fault starts harder when cold and puffs white smoke for the first few minutes. It is a low severity code and you can keep driving, but cold starts will get worse.
