the pipes connect to either side of dpf so the sensor can detect a pressure difference in dpf. if blocked the difference in pressure exceeds a certian limit and this triggers the regeneration process.

The fix is an oil & filter change and an ECU update, they say. The service manager says it's an oversensitive sensor relating to the DPF, which reports the oil has become contaminated and is putting the DPF at risk. The ECU update is supposed to reset the parameters for the sensor. Oil drop, filter & update is free, under warranty.
Depending on the vehicle, a certain DPS threshold may trigger a DPF regen cycle, but only if conditions are right. Some vehicles may trigger a DPF regen cycle around 15% capacity, for example. If conditions are insufficient for a DPF regen cycle, the DPF simply continues to collect PM emissions until they are.
I imagine it's in the same place as minelooking from the front, it's mounted on the firewall/bulkhead behind the engine on the right side about 20cm down from the top of the engine (from memory) Mondeo 2.2 TDCI Titanium X Sport (2011 MK4.5), Panther Black | S-Max 2.5T front brake calipers and 316mm discs | Fuel Log
The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. At one point it reports the charge status of the particle filter and monitors its function. At the other point it is used to control the low-pressure exhaust gas recirculation.
