Right from the EDR sight, thought I'd share this with the group.
Currently in Denver in 6" of snow and 10 below :-(
There are several vehicle models on which the glow plug position does not coincide with cylinder number, (eg. trouble code P0671 specifies glow plug number 1 but glow plug number 1 is
actually in cylinder number 4).
The only way to be sure which glow plug is faulty is to test all of them. This particular glow plug system on the BHW engine code, supplies 6VDC to the glow plugs.
