Brief introduction / De-Fap request...

[Stenasev]

Hi all,

I made one post about 4 years ago when I had a 2000 2.0HDi Saloon. I liked the car but not enough boot space and faulty aircon (I love aircon!) Nothing really wrong with it but only had it about 6 months.
Anyway fast forward 4 years I have just bought a 2003 2.2HDi Estate manual. Much better for space and working climate control! It's a bit of a fixer upper as has dpf limp mode fault as well as airbag and abs faults I knew about most faults when I bought it though. I have bought the obligatory pp2000 + galletto and have just read the ecu file. I am writing this so that I can hopefully PM some kind soul to do a fap delete
I would also like to ask if the information is out there on how to delete it myself (for free). I am quite happy to find it myself as long as I know it's out there! Had no luck so far. Tried ecusafe but must have been a demo or something as both files had same checksum.

Would really like the dpf/fap deleted as this should make the car driveable and then I can work on the other faults...

Cheers for now,

Steve

Steve,
Are you sure it's a dpf related fault as the anti pollution fault message covers a multitude of things.
Mine was a split pipe to the swirl actuator.

Hi Steve & welcome back aboard .

Ecusafe should work, but it's not very intuitive. I couldn't make sense of it at first either.

I'll drop you a PM with some suggestions.

Hi,

Thats interesting. I have only driven the car the 35 miles home since I bought it on thursday. I kept getting the fault message and limp mode. It went briefly after restarting but came back pretty much straight away.
Since I got it home and had a quick look over it I notice the end of the swirl actuator has broken off. Commonish fault apparently. I cable tied it back on but haven't had chance to drive it since.
Will give it another try before I remove the dpf but its going to go sooner or later I feel!

Cheers

Steve

Actuators are fairly cheap and straight forward enough to change.
First of all I'd watch for the actuator moving at around 2100RPM, if it does then the electro valve is ok and its just the actuator. No movement and it could be a split diaphram in the actuator, goosed electro valve or a split vac pipe.
Luckily the pipe is cheap and easy to change, electro valves are about £30/35 IIRC and you can test the actuator in situ by disconnecting the vac pipe at the EV end and sucking on the vac pipe to see if it maintains a vacuum.
Myself, Doggy and a few others are pretty familiar with the 2.2 vac system so shout if you need any more advice and post your location as someone may be near by.

Just remembered you can run an actuator test with Planet but I've not done it for the swirl actuator so not sure what it will tell you but worth a try as well.

I'm itching to start digging into this thing but so busy won't get much chance for a couple of weeks. I checked the swirl thingy today and it doesn't move at any revs. Found a couple of vacuum hoses that go nowhere, i think one is just missing the filter, the other came from the middle bulkhead ev (maybe egr?) Anyway i am definitely looking to simplify the vacuum system as others have done here.
Loaded diagbox on an old laptop, wouldn't connect. Looks like usb port problems even though worked with galletto. Dug out an even older laptop and will try that when i can.

While i think about it, if i get around to digging the dpf out of the exhaust is it considered worth taking the cat out as well? Any pros/cons etc?

Cheers

Hi & welcome (back )

As above: anti-pollution (with limp mode) is caused by all sorts of different things, not just the DPF. However, in any case, the DPF and vac system definitely need work.

Cat: if you can see through it then it's fine (tip from Doggy).

Vac: as I'm sure you've found the system can be simplified considerably. Note that it's very sensitive to leaks and that if your EGR is stuck open then it's still stuck open when you remove the vac supply.

Diagbox: I have a strong preference for PP2000 (which must be run under XP because it doesn't work in Vista or 7). It's much faster software, and does everything you need. Unfortunately, installing it is something of a rite of passage... There is a driver that needs to be installed for the computer to see the hardware. IIRC plug in the hardware, stuff in the CD, and ask it to install the driver from the CD and it finds it... if you're lucky. When plugged in the hardware should have a green light on it -- it's powered from the USB.
Technique: clear all faults, go for a drive, see what comes back. This is because loads of faults will have cropped up since last time it was cleared, and you want to know which ones are happening now as opposed to which ones haven't happened for months. Intermittent faults can normally be ignored.

Have fun

Bulkhead EV's are O/S turbo, middle - EGR, N/S DPF and Dozer controls.
Gutting the cat is supposed to give you a few more horses especially with a remap but don't forget the new MoT regs, it needs to 'appear' to be there and in tact as does the DPF.
I'd get the vac system sorted first.

Detach the EV bracket from the back of the air box, undo the MAF and remove the air box.
You should now be able to see the entire vac system except for the pipes disappearing to the turbo and EGR. For about a fiver at the motor factors you can buy enough pipe to replace all the soft rubber stuff. Keep the harder plastic stuff as it acts as a restrictor to ensure you have enough pressure to the brake servo in the event of a major leak.
As your actuator is known to be busted you might as well change that while you're at it, moving the TPS you should be able to get the bracket holding it to the block off, then access the 3 screws holding the actuator itself to the bracket. Sounds easy doesn't it

When you've done that you might find it fixes the anti pollution, if not it starts to get a bit more tricky but I'd cross that bridge when you get to it as the saying goes.

Simplifying the vac system only makes sense after DPF and EGR removal, you go from 5 EV's and a vac reservoir to just 2 EV's and a lot less pipework

If you have vac pipes that go nowhere then someone may have already been blindly tinkering!

[Stenasev]

Thanks very much for all the help and advise. Very much appreciated. I am much more clued up than I was before this thread.

Looking forward to reporting back with my progress...

Hi. i have a 406 2.2 coupe HDI and have the DPF light on. i want to remove it and clear the ECU. can you help me please. Will

Remove the light, or remove the DPF?

Post up your location and someone locally can clear the fault with PP2000, the Peugeot Diagnostics...

[griffiths101]

i'm in Hampshire (near Portsmouth) i want to take away the DPF all together. i now have had a lot of help from Doggy. (great guy) and am planning on doing it next week. my plan is to unbolt theDPF use a drill and other tools to hollow it out. refit the hollowed DPF then upload the new NO-DPF ecu file onto the car using a MPPS flasher...


Any opinions on this process? thanks in advance. Will

[GingerMagic]

The bolts that hold the DPF on can be tricky, grab some spares ( M8 ) before starting. I hollowed mine out with an axe, then a screwdriver and hammer - still took an hour to do...

Wear a mask too.....

[OllieNZ]

If you can get an sds drill and chisel. I tried drilling, pry bar etc but ended up using a pneumatic rivet gun with a chisel bit and it flew out. Also +1 on the mask

I know what you’re thinking: 'Did he hit the dpf six times or only five?' Well, to tell you the truth, in all this excitement, I’ve kinda lost track myself. But being this is a 14lb sledge, the the heaviest hammer in the workshop, and would knock your head clean off, you’ve got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?
