DPF tests in Europe, all Vigo's fail?

[xychix]

In europe (now belgium and netherlands) have a particle counter that will count particles in exhaust fumes while stationairy. Limit is set to 1.000.000.

The assumption is that with a working DPF you'll always be below that number.

A friend of mine gets between 2.000.000 and 5.000.000 every attempt.
My APK (yearly health check for road approval) is valid till december so I've for 11 months to get this sorted. My mate however had only 3 days...

I did a voluntary testrun and also scored 2.000.000

We've tried everything:
MAP / MAF / Fuel Filter / Diesel Filter / Gass To Liquid fuel / DPF cleaners etc.

I know this is likely no issue for the majority of the forum visitors, but if there are any bright minds to think along.... more than welcome.

Replacement of the DPF is costly (2.000 EUR ~ 2.200 USD) and is not always helping (as we've received from the Belgium friends that work with this system for 6 months now.

The questions:
- Does anyone have a good idea on seriously dropping exhaust particles at stationary
- Does anyone have god-like DPF skills and is willing to help out with ideas on how to diagnose the DPF filter.

Hi
Hand it to Toyota and tell them to make it comply.

I foresee a statement of work:
new DPF 4.000 EUR (~4200 USD)
injectos 4.000 EUR (~4200 USD)
all filters and serivcee 500 EUR (~525 USD)

without guarantee it will pass
My results with the dutch dealerships aren't the best. It started when they refused to replace diff and transfercase oil after a week of offroad. Those lubricants where 'for life'.....

But let's not make this about dealerships . Was hoping people have experiences with DPF innerworkings, quality of different brands etc.
