Hello, I have had a 307 2.0 Hdi (110bhp) for around twelve months and had nothing but trouble with it. Initially the low fuel additive indicator was displaying and the engine management light illuminated. The additive was replaced and the light re-set, however within a day the display message and management light were back on. The garage where I bought it from (and will never buy a car from again) finally decided that the switch at the fuel filler cap which allows the additive into the fuel was stuck open and so they fitted a new switch and re-set the engine management light. All was fine until the day after when the light came back on, and so back to the garage to clear the fault and re-set the light. This escapade carried on for well over a month! Eventually I really could not be arsed keep going to and from the garage and drove the car with engine management light on until last week. In the meantime, a friend of mine who has the Peugeot software checked the car for faults and managed to clear 32 faults that were showing. However, there was one fault that he could not clear and that was to do with the particulate filter. He explained that the filter would probably be blocked solid which makes sense because recently the car wouldn't pull a mugger off my granny as it lacked that much power. I carried on driving for a week after this and the engine management light came on and went off on it's own accord but has recently stayed on permanently. The car is off road now as the MOT was due today and it wasn't worth taking it for test with the engine management light on. I have been told that it is possible to clean out the particulate filter by either keeping the engined revved up constantly until the exhaust is to a certain temperature which is supposed to clear the build up of carbon or it can be removed and washed out similar to an heater matrix. I would appreciate any advise on this?

You'll need to remove filter and wash it out , then with pp2000 reset it as new , plus refill Elroy's if needed and reset counters , I would guess on yours there's two and the original garage only reset one ,

Personally I would get it to a mapper and rip it out

or you could just remove the DPF/FAP and do away with it far better all round
but when I washed mine out I used warm water with some degreaser filter was like new but after a few weeks it was back to faults so I removed it and never had any faults since :thumb:

Pressure washer is the best way to clean these my original filter got to 202K with a couple of washouts.

That's good mileage Windy1603! I traded in my 206 van (with the 1.4Hdi engine) against this 307 last year and that had 208k on the clock!

If I was to do away with the DPF/FAP is there an exhaust section that replaces this or would I need a full replacement exhaust system ?

Also on the subject of the re-mapping involved, can the ECU be removed and sent away to have this done or does it have to remain fitted to the car?

any local exhaust place can make you up a straight pipe to replace the FAP/DPF filter for about £20/40 but if you do this keep the FAP/DPF and you
can sell that for scrap so this could be used to re coupe some money back ive seen places give 50/100 for some filters theres a code on the it so might be more!

getting to the remap you can do this without sending the ECU away buy a lead on ebay and read the ECU file and send it to a tuner and they will remap the car from the file send it back you upload it and bingo the car is remapped :thumb:

so is there a diy way to do this remapping? My filter still works after 220k (km!) but not worrying about it and the dpf fluid and the turbo would be nice.

yes there is a thread here somewhere titled dpf removal under £100 do a search and you should find it,
to the op a knackered differential pressure sensor will give faults as a blocked or punctured dpf

As of April new requirement of MOT is to look for presence of DPF on all cars fitted with then as standard but not the operation.

The electronic test sheet the tester gets from your reg will detail if DPF was fitted as standard, no cut off year detailed in draft manual.

If removed eg with a link pipe instant fail. Should be OK if case in gutted but in place (but talk of lower smoke test limit for DPF cars in near future to part test DPF operation)

Thanks for the info CMax 7 :thumb:

Just my bloody luck, the Government are to tighten up the MOT inspection from February 2014 with regards to Particulate Filter removal (See the link below).
If Roads Minister Robert Goodwill knew what problems and expense a DPF involves when it becomes blocked then he may have a different view on things. Then again a politician would have more money than sense so it wouldn't be an issue for him and again I couldn't see a politician owning a car long enough to experience the faults that occur after time :mad:

What problems and expense? A conservative estimate of 500 quid and you'll get 80000 miles out of it. How much is that per mile?


And UK politicians hands are tied. It's an EU directive and a good one. If we didn't have them then water companies would still be dumping sewage into rivers and seas.

The problem is with my 307 is that it was due it's MOT two weeks ago and the engine management light is on because of the blocked DPF which is a MOT failure.My friend who has the Peugeot Planet could not remove the fault and so the dpf will have to be replaced. I was reluctant to spend £500 plus on a car that has had many other electrical problems recently such as a faulty COMM unit which had to be fixed at great expense, a faulty electric door mirror and drivers door central locking unit. A quick pre-MOT check revealed a track rod end and ball joint required replacement which would have been fine if it were not for the dpf unit problem. I am now left with a car that has no MOT and unless I spend £500 plus, I have a car with little more than scrap value. I wanted to sell this car as we also have a 206 2.0Hdi sw (Without a dpf) and we no longer require both vehicles. Particulate filters are all well and good and being a commercial vehicle technician I fully appreciate the good that the filters do. Unfortunately sometimes the expense of the replacement is far too much expense for the average motorist who owns a car of this age hence the number of people on here who are asking about or have done away with their particulate filters.

Of course it won't. A fault is a physical thing, clearing the codes won't fix it.

CATS2U - about £120 for a new DPF. Just make a big deal when you're selling it and reassure the potential new owner that it won't need doing for about 70k and you'll recoup the cost.

Its like if you went to the doctor and told him your problems and he listened and just sent you away without any medication.

Is the EML being on an MOT failure? There seems to be conflicting stories about that.

where is the car, mileage and service history and what do you want for it?
