was down at halewood the other week on a factory tour speaking to the guide we got onto dpf filter now beenig fitted to all diesels he was sayin in general they are not a problem if maintained properly ie driven i accordance with instructions supplied but he also said that there was an adertive that you can add to the fuel tank has anybody herd of this and does it work  rainy-city

how can LR sell you a car then preach on how to drive it? the car should be designed to suit all driving , city or motorway. If it isnt its their fault

I've heard of it but don't know if it works.
The Freely purely relies on our driving habit and ECU adjustment to replenish the DPF filter which should last a lifetime, whereas most Fords and others have a small tank filled with DPF cleaner that is injected in a very small dose per tank, this fluid can cost up to £800 to replace after anything from 25-50,000 miles.
I believe the LR guy was talking about an additive costing about £30 that is poured into your tank and lasts about 10,000 miles. It supposedly attracts the minute soot particles and allows them to be burnt off to an ash at a lower temperature, whether it works or is worth it, I don't know.

the small tank isnt dpf cleaner its adblue, urea injected into the exhaust to reduce emmisions, nothing to do with dpf. At work

It is CG, Adblue is injected into the exhaust stream and is entirely different. This alternative DPF system has another tank for the fuel. Citroen and Ford use a different regenerator to Freel's, a FL2 has it's DPF close to the manifold so relies on a higher temperature.

Quote:

There's not always space close to the engine though so some manufacturers use a different type of DPF which uses a fuel additive to lower the ignition temperature of the soot particles so that the DPF can be located further from the engine.

The additive is stored in a separate tank and is automatically mixed with the fuel whenever you fill up. Only very small quantities are used though so a litre of additive should treat around 2800 litres of fuel – enough to cover 25,000 miles at 40mpg.

not entiley true yes ecu does adjust the burn slightly but vehicle still has to be driven above 2,000 rpm for approx 20 to 30 mins according to the instruction sheet this is most important if the car is only doing town work otherwise dpf will become blocked if the car is dooing mixed driving motorway/town it should not pose a problem does anybody know if this adative is avalable  rainy-city

That's what I said

•Not compatible with automatic additive systems (PSA FAP, Elyos)

Just driven from Lancashire to Birmingham, gentle drive not in any rush, the Car has not spent 20 mins or more above 2000 rpm, does this therefore put it at risk?
I think the extended drive will have done its job

It's strange as there doesn't appear to be a hard and fast rule to this. My driving in the summer takes in all habits of driving and would seem to fall in with their criteria for regeneration but 6 months of the cooler months I mostly travel to work and local 'B' roads, in my mind not enough to regenerate but I have never (yet) had a problem in my 13500 miles
Perhaps it's software related, ie updates or just pure luck or could it be quality of fuel related

thanks eyorkshire have put into favorites for later  rainy-city

You're welcome Alf, because of the problem I have read up on it and tried to understand it (as much as I can ), but cannot understand why some are not affected and others are when driving habits are similar.

We have had a DPF since new, 4 years ago, and the first three yearly service an expensice (£30 quidish) DPF addertive has been added to the fuel tank. Never questioned it although last year I had to have a new DPF system fitted due to the DPF being FULL and they or I were unable to clean it using LR's stupid cleaning receipe.

Anyhow, this last recent service (4th) was done at our new LR distributor and they quite rightly used the "correct" oil C3 spec. and did not use the addertive. When questioned about this they said they could add it if I wanted, but didnt realy think it neccessary using the correct oil spec (which the last service station has apparantly not). However they did say that by adding the expensive little bottle of addertive it may reduce the DPF problems that may develop by continous town driving. I dont drive much in towns and therefore will decide what to do next service if I still have Freely. 2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

It would appear to me that DPF filters were NOT fitted to earlier models. Is this true and if so when were they first fitted?
ie what was the vin number from which they started fitting DPF filters ? Does any one actualy know.

Didn't the DPF become a standard fit for the UK on MY10 models.
