Multiple warning lights, no power. 2008 vRS PD170

Evening all, picked up a 2008 Octavia vRS PD170 bus with 150k miles on the clock two weeks ago due to my MK3 vRS CR184's DPF failing, bought the PD to use on holiday while my main car was having a good used replacement DPF fitted. The MK2 PD was running a treat until today when DPF light came on, followed shortly by the flashing coil symbol and shortly after that the EML came on too for an unholy trilogy. Only got a ****ty OBD2 reader with me which showed one code " particulate filter pressure low, bank 1"

Could this be a G450 sensor failure? I'm stuck mike's from anywhere in Norfolk at the minute, is there a temp fix anyone knows of until I can pick up a new sensor? 

All suggestions welcome.

Cheers guys.

Andy
