As the title says, I have a 1.6 206 hdi, 110, as well as my 406 and it has flashed up the. Dpf needs unblocking. I have been quoted £400 - 450 to remove the guts and delete the dpf from the ecu. Supposedly it is different from the 406 as it has a pressure differential sensor to contend with. I have read it needs the guts removed and the ecu mapped and I have also seen others have simply unplugged the sensor and deleted the dpf tag after removing the guts. Every report says to fill the eolys tank with diesel.
Anybody know anyone who has done it and how?

The 2.2 hdi in the 406 has a differential pressure sensor

Do you know what ecu it uses?

You may be able to remove / pressure wash / thoroughly dry and refit it to gain some breathing space. That's what 2.2 406 coupe owners did before we found out how to delete it from the ecu. May still be a howto on the coop forum?

Not a lot of info on the web re this particular model it may just need a top up of fluid and not removal. I have found the tanks position from service box, next to fuel tank not in boot as some people on web have said, and fluid type. I can get the fluid and a refill kit, £40 for a litre and tubes, the ECU is a EDC16C34. The counter function needs to be reset after refill, I do not have kit to do this, can it be done with a code reader or do you think it needs planet?
A real PITA system.

Unfortunately I think the dpf/cat is not original. On service box it shows as a 2 part assembly but on the car it is a one piece job. When I bought the car the heat shield on the turbo had been removed, read torn off, and was leaking on the exhaust turbo joint. I was told that Formula One had done some work on the car, poor outfit. That's why I'm leaning towards low additive levels as it may have been replaced.

Making the assumption that the 1.6 in the 206 is the same as the other halfs 307 then the remap is a bench flash job so not something your average DIY mechanic should go anywhere near. I was quoted around the £450-550 mark for the remap and gutting procedure, still considering whether to bother as she doesn't like the car and it may be gone soon.

The remove and clean option is straight forward enough but ideally you still want to reset the counter with Planet to stop the warning light and of course top up the fluid if needed.
The DPF on the 307 is straight off the turbo at the front of the engine and you'll probably see a bit of soot around the turbo inlet pipe from back pressure caused by a blocked DPF.

I've cleaned it twice now and normally get 3/4 months out of it before it beeps at me again, ideally you want to whip it off and jet wash the hell out of it, be careful where the dirty water goes as its pretty toxic stuff.
Then I leave it over night to drain, fit it back together in the morning and take it for a motorway blast with every accesory I can find turned on.

Personally I'd say if you're planning to keep the car for at least a couple of years get it mapped, if not jet wash, you'll need at least a couple of years to save the remap costs in fuel costs.

Wonderful Although burning it off into the atmosphere obviously causes no pollution whatsoever

Somewhat off topic, someone posted up another "MOTs are changing and everyone that's removed their DPF is gonna get their hands chopped off" thread on the C-Crosser forum (one can dream ). I kind of pointed out that, at present, they can't tell what's inside the thing, nudge nudge wink wink and got the thread locked by a mod - "blah blah blah illegal blah huge fine blah". Thing is I actually read the DoT stuff and if you remove the DPF, not only is it increasing the emissions to a level above the arbitrary, think of a number and half it, amount the car was licensed to be sold at, you'll also be reducing everyone's life expectancy by 20 WHOLE DAYS!! You selfish bastards I was gonna, umm, invade Poland!

Yep, when I bought it there was soot around the turbo but I think that was down to the clamp being the wrong size, correct size clamp fitted and no more soot. This is the Gti model and uses Bosch Ecu, a friend had his 307 mapped and yes that was a bench job, it was a Siemens.
Anyway I am having the Eolys tank refilled by dealer, £190 inc vat. It was going to cost between £450-380 to defap and if I was to refill the tank fluid was going to be £130 for me to buy and then the counter had to be reset so in the end a dealer refill seemed best option.
Dealer said it was an pointless item but only option is a refill or defap.

Try hdi tuning ltd he quoted £150 for the remap on my 1.6hdi 307 and I was going to gut the dpf myself. You can even post him your ecu and seeing as it a bench job anyway.....
The other thing to consider is you will need a new dpf aswell as the fluid topup as it will be clogged with ash and cause issues sooner or later

Hdi tuning were my first point of call, however they said they were unable to do it due to moving premises and someone being away for six months. Only doing online stock maps.

Yes, I asked them the same thing about doing DPF delete + a small remap to my 407 but was turned away.

Oh barsteward. I was hoping to get mine done soon.

Okay, having had the tank refilled, £180, a new problem has reared it's head. The message on the mfd wont turn off. The poxy control unit behind the fuel filler cap is knackered. Cost, another £140. This brings up the cost of the eolys refill to £320.
Take my advice and get the whole lot removed.
