Ecu Dpf Removal Remapping

[ataxidriver64]

Hi I have noticed a few of the big ECU remappers that advertise on the net, are now offering the service of DPF/FAP system removal off the main ECU, leaving you free to remove the particulate filter off the vehicle.

Has any one had this done to their car, or know any one that has? and if so what was the result.

I have spoken to a remapper offering this service, and the price quoted seems very reasonable, they even offer the service of dismantling the FAP for you if you want.

I know for a fact the removal of the FAP and CAT converter will in no way affect the MOT.

Any info would be appreciated, as this is a route I want to go down to get the most out of my C5 2.2 hdi auto.

 

 

Thanks Al

Not sure why you'd want to remove the DPF. Personally I prefer not to leave clouds of soot behind me when I gun it. Maybe there is a fault with your system. I have an '03 2.2 HDi (admittedly manual) estate which returns 47mpg with reasonable driving, goes very well and gives no probs whatsoever with the DPF system as long as you maintain it correctly. The car has 125k on the clock and was MOT'd last week. The smoke emission result was too low to register. I used to own a 406 without a filter and that was a lot more smokey.

Hi my car is a 2001 model, and have had it 2 and a half years it has now got 190000 miles on the clock, I use the car as a taxi, for the first 2 years the DPF system worked fine it was done by citroen just before i bought it and has covered the 50000 miles it is supposed to do, any way now the system isn't working, been quoted aprox £600 to sort it as the additive ecu is bust plus a couple of sensors and it would need the eloys and a FAP (a few big holes may be drilled through it and the cat just to stop it blocking up), what a con that is I jet washed mine out and now its fine, plus labour, it just isn't worth paying out to sort it properly as I will only be keeping it on the road for 6 months max, then it will be off to car heaven.

I would be happy if I could stop it going into limp mode every time I stop then start the engine.

Re. MOT that was done yesterday and smoke test was 0.97 the limit is 3.00 and thats with the system not working!!

Any way thanks for the reply, and I hope you enjoy your C5, I have but only because it was an AUTO.

[Guest digitalinkjetman]

I had my DPF and CAT of recently at 90k miles when they blocked up.

 

To be honest I just flushed them through with degreaser and blew them dry...

 

Never worked so well, I've also removed the rear silencer to help remove any back pressure!

 

Again all works and sounds okay with no added noise!

 

Oh and it all passed the MOT yesterday fine!!

I have removed my fap and cat on 2.2 c5 hdi 2004, and all i can say is you will not re-instate it after you have drove your car without it. i have a lexia but this is not used to remove it from the ecu you need a galletto cable to read your ecu file to laptop, Then run your file through software that removes all reffrences to the dpf and eloys from the ecu. Once the modded ecu file is done simply write it back the ecu then take the dpf and cat off exhaust and smash the guts out of both and refit to car. I have done 3000miles now and my car pulls like a train no black smoke 4-5mpg better fuel and flew through mot. total cost for me was £25 for cable and 3hours of my time to remove and refit exhaust. This also dissables the eloys additive from working so no more dpf or eloys to worry about again. Did a mates peugeot 406 2.2 hdi yesterday he can't believe the difference in performance. Any more info or help just mail me.

[ataxidriver64]

Well car is now minus a cat and particulate filter, what a difference, just the ecu to sort now.

hi there, i've just stumbled onto whats written here after hours of searching on google. Seems to me this is the path to go down, my c5s not been running well for ages, its been on numerous scanners etc, had eloys topped up and ecu supposedly reset. Well the esp & antipollution faults are still coming back.. i am very interested in finding out from you how to go about chucking away the bits citroen cant get working. many thanks

Hi its early days yet, but early signs are looking good, performance isnt back to 100% yet i dont think, but hopefully a follow up with an ECU remap will sort it out.

Basicly the particulte filter has been emptied and the cat, so now its a straight through pipe. esp/asr fault doesnt show as often now, but when it does it only cuts the power for a few minutes, then back to normal, until the next restart.

My car being a working car I dont turn it off often.

at a guess I would say your system isnt working and your FAP is blocked.

Alan did you buy the galletto cable to read your ecu, i have mailed you a few times.

[ataxidriver64]

Not got the cable yet, hopefully will have it next week, I havnt recieved any mail of you i'm afraid.

So looking forward to getting this off the car.

thanks Alan

Hi,

 

I'm interested in this but is it not illegal to run a car without a cat? Can the FAP just be removed? If the FAP is removed surely there will never be a blockage and hence the ecu will never call on the eolys system anyway?

 

Best wishes,

 

Bob H.

 

PS how do you make the previous post appear in the neat green box?

[coastline taxis]

Hi. Got the cable but havnt got a 2.2 to try it on ha ha. Anychance you could put the procedure on here or pm me so i can keep it to one side for future.

best regards

No. With diesels all they test is the smoke. Early HDI's didn't have filters. But it's no good just removing the filter. The ECU needs to be told that there's no filter system present.

Hello Al - I had a chat with Andy of ECU-Flash before Christmas and when I can arrange the logisitcs of getting my old C5 (2001 2.2HDI, 125,000 miles), which is now driven by my daughter-in-law, from New York to Sheffield Andy will remove the DPF filter and remap the ECU.

 

If this cures the antipollution fault and associated "limping" it will be money well spent. Having had the car from new, I had the DFP and fluid replaced at 5 years 73,000 miles, so it's probably due again.

 

I will report back after the job has been done and the car has been driven for a few weeks, so it will probably be the end of February by then. If all goes well I will then get my 2003 2.2HDi done before I get any problems.

[ataxidriver64]

Well just an update, DPF has been emptied and also the CAT, before remap. its recomended to remap before the deFAPing and deCATing.

Remap done curtesy of woodywoodpecker, although I do have the software to do this, I have put the remap on to the ecu and everything seems to be running as it should, only problem I have is the fuel consumption but that could be down to the after market air flow sensor (another part that can cause an ESP/ASR fault) well since the remap done about 1500 miles and had no problems or warning lights.

Yesterday I put back on the original ECU map to eliminate the fuel consumption being caused by the remap, it is still returning the same, I will be trying an original citroen air flow sensor some time soon, as I suspect the after market sensor is over fueling.

I will let you know the out come, but from what i have seen this remap does do what its supposed to do.

What i did notice, is the car went into regen mode tonight after doing about 140 miles, but no warning lights apeared.

[Big Al]

I stand corrected - my mate just did the DPF removal on his '02 2.2HDi and quite frankly the engine appears to run just as cleanly. He did it to avoid the expense of a DPF swap and Eolys top up. Plus it's a one-off cost. His mpg hasn't changed although he thought he might get a boost. Mind you it's pretty good at circa 49mpg anyhow.

Update - I took the car to Sheffield on Monday (90 miles in limp mode) and the guys there removed the innards from the DPF and did the re-map with Andy of ECU-Flash providing the files via the internet. I was at the garage all afternoon as they had other jobs on at the same time and so I left Sheffield in the rush hour.

 

The first time I put my foot down reasonably hard was on the slip road to the M1 and the message came up "Particulate filter not connected" (or words to that effect) and the car went into limp mode. However, it limps much better without the DPF! On starting up now "Anti-pollution fault" appears for a few seconds and then goes out, but the warning lights stay lit (service, engine auto-diagnosis and ESP/ASR symbols).

 

On getting back to Lincolnshire I tried a few tests on the quiet straight roads. From a standing start accelerating hard up to about 3,000rpm the car goes quickly in first and second gear, but on changing up to third (which puts the RPM back down to just over 2,000) there was little acceleration. Accelerating through the gears it was possible to get up to 70mph on the M18 and A1, but with no "poke" to accelerate further at all.

 

I am still waiting for Andy to call me back to check if there could be a problem in the re-map. However, I suspect that we still have another problem to solve before full performance is restored. My son will take the car to work (he works in the motor trade) and get the fault codes to see if there are any pointers there.

 

At the moment I am reluctant to take my non-limping car for the DPF removal/re-map until we get this one sorted out. However, they had 27 vehicles booked in for DPF removal in Sheffield this week, so it must be coming increasingly popular as a way to avoid DPF problems.

Hello Bob

 

No update yet - my daughter in law is managing to do local journeys in the still limping car. Hopefully we will have time to take another look at it in April. My suspicion is that the DPF removal and remap was OK and we've got a turbo/vacuum problem - possibly a leaky/bunged up hose.

 

David

 

I've just got the French manual from Amazon, so will be swatting up from that before we do anything.

[deBooza]

Hi

 

I own a 2002 Citroen 2.2L Hdi Exclusive.

 

I'm so glad that these cars can now be de-DPFed! I get an Anti pollution warnig come

on every 3 weeks or so, along with the ASR etc. Actually, I can get it to come on by driving in 5th gear

at 50mph. Two to three minutes at that speed and the warning comes on and we are in limp

mode - really hacks me off.

 

On a Pug forum I found a sort of tutorial on how to remove the DPF yourself:

http://www.406oc.co.uk/viewtopic.php?uid=8168&f=10&t=12487&start=0

 

Anyway, I believe the Pug 2.2 Hdi and C5 2.2L Hdi are the same engine, please correct if I'm wrong.

 

I am going to remove the DPF system on the car. Does anyone know if the exhaust is similar to the Pug,

that is, same sort of unit that can be undone, gutted, put back, and away you go?

 

Thanx

Well, we will never know if the DPF removal/re-chip really worked or not as my daughter in law has just traded my old C5 in for a Zafira. So if anyone picks up a silver 2.2HD1 SX estate reg'n. K*51 E*B and gets it going let us know!

 

At least I can start to work out what the French manual says at my leisure. And no, I'm not going to get involved with the Vauxhall before you ask!!

[Guest majorjam]

Just for infomation, My understanding is if the particule filter is blocked it will say on the multifunction display 'Diesel filter blocked' as well as the 'anti pollution' So if you have the 'anti pollution' and maybe 'esp asr' warning only that would mean an engine problem most probably vacuum/egr related (check swirl diaphram!!) :rolleyes:
