Glow plug coil flashing

[johndeere2130]

Hi,
my 2.0TDI 143, has this flashing coil coming on every journey without any other warnings and no loss of performance,
When i press the set button while stationary, it show a bulb failure, but i can't find a single buld gone!
Has anyone come across this before?

It may be your DPF getting bunged up; or the sensor that senses the DPF getting bunged up going faulty. Either way you need someone with a diagnostic machine to check for error codes or force a re-generation of your DPF.
