Fault code P0671

[Paul43]

Hi guys got I car tonight and the engine management light came on after starting it. Fault code read P0671 . Could it be as simple as a new glow plug or is it more involved. I have a Leon fr+ 150 TDI. Any help would be much appreciated. Thanks in advance

it could be a glow plug
you can check them with a circuit tester for continuity
remove bridge loom and connect one end of the circuit tester to battery positive then the other end to the glow plug
if it lights up then the glow plug should be ok
the bridge looms play up and i would replace that it connects in the plastic trunking behind the battery
