Hi, is this filter covered on the 3rd year warranty ?
its done 27k, and had all services on time, I new one is £920 !
so beware

If anyones particularly worried about the dmf on their Doblo you can have it changed for a solid flywheel at time of clutch change, Fiat have an alternative part number. I had it done to my previous Doblo. You need to find a dealer with half a brain and perhaps threaten them with torture, but they will get there in the end.
Its unlikely to be a blocked dpf filter, if the ecu is not capable of doing a foced regeneration the dealer needs to look for reasons why, there is a service news with approx 20 checks for this fault.
The DPF or rather the lack of one was my particular reason for buying a 105bhp model Doblo. I have had bad experience with a late model Stilo with a dpf and also an Audi A4 which became a total disaster because of the dpf.
Having recently bought a 105hp doblo dynamic (which i am very pleased with) I was pleased and somewhat relieved to read the above post.
Just wondered why there is no pdf on this model when it appears to be fitted on numerous other diesel powered cars?

my 105bhp 06 cargo also does NOT have the DPF fitted.
The 105bhp 1.9 8v multijet in the Doblo has a fixed geometry turbo and therfore no DPF fitted ,the same for earlier 75bhp 1.3 16v multijet versions with fixed geometry turbos.
The later 85bhp 1.3 16v multijet and 120bhp 1.9 8v multijet versions have a variable geometry turbo ( VGT ) allowing for the increases in power both these engine units have a DPF fitted.
So if you are concerned buy the 105bhp 1.9 or earlier 75bhp 1.3 versions.
we wil all soon have no choice as the new 1,6 multijets and current 1.3's have DPFs so keep hold of your old dobbies
Forced regeration, ok, natural regeneration occurs when certain circumstances occur during driving, cruising with a hot engine etc etc. If those circumstances do not happen (short journeys, city driving etc etc) then the system cannot clean that dpf, so after monitoring the pressure in the dpf the warning light comes on and it goes to your dealer.
The dealer checks through everything and then carries out a forced regeneration using examiner. They stick the car outside or up on a ramp (you need as much cold air as possible around the dpf) and if inside fit a remote exhaust extractor (if you fit it directly to the exhaust it would melt). Secure an area around the car so no one gets too close, and start the regeration, the engine has to be hot, no pedals pressed and a load on the engine (lights etc). Examiner revs the engine to 2000 rpm and monitors the parameters to make sure its safe to do a regen. After this check, the engine is then revved to 3000 rpm and regen starts, it takes approx 15 minutes and sparks and soot are ejected from the exhaust. The injection period is extended and post injection occurs which super heats the exhaust and dpf, raising the temperature to between 600 and 800 degrees c, burning off the particulates that are trapped in the filter. After regen has occurred the vehicle is driven hard to flush out as much soot as possible, typically the pressure difference between before and after regen in the dpf goes from 150 mbars to 10 mbars at idle. This pressure difference increases as the revs are raised.

Chris, does this mean that the 105bhp has a bog standard exhaust system which would be (relatively) cheap and easy to replace compared to a DPF?
