Dpf help needed!

Post by Martyb5.5 »

Hi my newly purchased b6 tdi 170 bmr engine has gone into limp home mode. A week after buying the dpf light came on and i took it fir a drive it went off after 20 mins. Same happened 3 times in 3 weeks but the 4th time it stayed on and after 30 mins the glow plug light and engine management light came on. I have scanned and the error for g450 pressure sensor came up along with 4 failed regens. My question is should the light have gone out the first 3 times if it failed to regen?
These are my figures below I have ordered the g450 sensor but is my dog knackered also?
