Just wanted to add to this thread.
Yes you need the paid version of
MultiECUscan and the correct cables.
I got this from the Google Multipla Site

Under "Diagnostics" - How to Run Diesel Particulate Filter Regen and Reset
FiatECUScan diagnostic software can manually start a regeneration, and it can reset
the DPF counter by resetting the oil degredation light.
This is possible in the free unregistered version, but make sure you are running the
latest version – currently 3.4.2. Edit---this is incorrect.
If you cannot find the DPF menu, this is how. You don't even need to connect the
laptop to your car to explore the menu.
1. Select Fiat Multipla '02 1.9 JTD. Under 'System' select Engine, and under 'ECU'
select Bosch EDC16C39 CF4. If you select EDC15C7 you won't find it.
2. Press CTRL-F10. This connects in demo mode, so no cable or car needed. When it
says ‘Invalid ISO Code’ press Y (for the purposes of the demo – normally you would
select a different ECU if it says invalid ISO).
3. Press F4 Parameters. Scroll right to the bottom to see all the DPF and oil change
parameters.
4. Press F7 Adjustments, then click on ‘Particle Filter Regeneration’ for full
instructions on how to do it.
5. Under F7 Adjustments, click on 'Oil Change' to reset the flashing oil degredation
light.
Make sure the ignition is on but that the engine is not running.
Did it this evening so happy there is no more flashing oil light.
Not if only I could get the bloody thing to start more easily!!
Anyone in the Cork / Limerick area of Eire who needs this resting, give me a shout.
