DPF questions

[GreyWolf]

Hi,

For anyone with the 3.0L TDI engine.

1. If you use a monitoring tool for the DPF have you ever noticed a sudden jump (>15%) in soot% for the calculated soot mass?
(If anyone knows how this value is calculated would be great. It appears as per the manual it incorporates air mass flow, lambda, dpf/turbo EGT's & DPF differential pressure sensors)

2. I am curious if I have an intermittent sensor issue. Have you needed to replace Lambda (G39) or DPF pressure sensor (G450)?

Cheers,
