Octavia mk3 vrs tdi the dpf keeps regenerating far to often and still regenerating when soot is at 3g so scanned car today and this popped up had mixed info saying maybe pressure sensor then maybe rail pressure regulator and also maybe 1 on the pump or even the pump so after bit more guidance... 👍🏻👍🏻

Fuel pressure issues are a nightmare to diagnose as there are so many components that can cause the fault 😭 

That's it so wanted to know most common failures as maybe process of elimination

Not sure if this helps at all.....?

Checked fuel filter today and no signs of metal shavings or particles 

You need to do a proper auto scan/road test and get someone who knows what they are looking at to go through it.
