OK – here goes…
Caveat first – I did say “specific” rather than interesting!
Engine management light came on (2009 Mondeo 2.0 diesel). Plugged it in at the local mechanic and it came back as P2002 Diesel particulate filter efficiency below threshold bank 1. Knocked the light out and the mechanic recommended a good run in the car to allow the filter to regenerate. Had my doubts as the car had been on long runs recently so shouldn’t have been that.
Sure enough, light comes back on which leads me to tinterweb and the following forum post

I took it back to the mechanic and sure enough when up on the ramps the rubber hose as described in the link was broken – it had hardened and perished. Looking these up at the local Ford dealer and they want £115 quid for a couple of rubber hoses!!
My questions are: –
1. Have these parts been upgraded as the originals obviously aren’t up to the job of being near such a high temperature part of the car?
2. If not, then have any aftermarket parts been made available instead of Ford parts?
3. If no again, should they be wrapped in foil or similar to protect from heat when re-fitted?
4. Finally, will a couple of lengths of fuel hose or similar be acceptable as the hoses simply connect at both ends with basic clips i.e. are there any gizmos contained within the hose that makes them special and so expensive? They are listed as a “sensor assembly”.
Part number is 1440559 for anyone with access.
Many thanks
