Hi, newbie here. :cool:

I have a 407 1.6HDi that went into limp mode then blew the turbo. Found out the DPF was totally blocked!
NO engine fault messages came up on the display at all yet I do get bulb failure messages etc... Is it possible someone has 'programmed out' engine fault messages, is this possible with Plant or other software?


thanks for your thoughts...!

No it cannot be programmed out using planet but it could be using other software your car MAY be mapped with no DPF but its hard to tell

Your DPF was probably clogged up due to the system not regenerating there are various reasons for this and if you dont fix the problem the same thing will happen again

Turbo failing may have dumped oil into exhaust and this is why your DPF was clogged it may not have been the DPF that killed the turbo

As i say there are many possibilities lack of proper servicing short journeys not revving engine enough all contribute to problems.

Thanks for your answer, it makes sense.
The car was trying to regen. as the cooling fan would 'run on' for ten minutes after the engine was switched off to cool the DPF. I have had a steep learning curve with this car as I knew nothing about DPFs a month ago!
Anyway, the DPF now has a few healthy holes drilled into it (shush, don't tell anyone) so will not block again, and I have fitted a new cartridge to the turbo, and refilled with fresh oil and filter. Happy days.
No error messages so far, and not expecting any!

I hope Mr MOT man does not see the few healthy holes drilled in the dpf.

It's recommended that you replace all oil feed components too, there was a service bulletin to this effect on the 1.6hdi. PM me your email address and I can email you the service bulletin

Drilling holes in the DPF wont cure the reason it blocked in the first place you will still get issues relating to the DPF unless its mapped out the system.

I am very much in the make it work camp with DPFs as removing them can cost more than actually fixing them the system just needs everything working properly its not that complicated my 307 had 170k miles on its original DPF and still regened fine every 300 miles

Unfortunately due to my commuting style, this car would never get a sufficient run to allow a regen to finish. And I'm not about to go for a 30 minute blast up a main road to let it work as this would waste fuel! As you can tell I'm not a fan of DPFs and maybe I should have bought a petrol car but for now, this one is running. Mr MOT is only allowed a visual inspection and to the eye, the DPF is present, as long as I pass the smoke test at MOT time, I'll be a happy man, if not then the car will be listed for parts on Ebay. No loss :)

This is where you are wrong its not necessary to go a 30 minute blast to clear it it only needs a steady run at a steady speed and if the system works properly it will regen i did not go out my way to make mine regen and as i say if your system is not mapped out the holes you drilled will make matters worse !

Little Puggy 407 back on the road, happy days!
Unfortunately the little beast is still trying to regen so the cooling fan runs for 5 minutes after every trip...
Can someone advise the best software/cable combination to delete DPF/EGR?
I'm after really low budget stuff so something off Ebay for £20 will do.
Also, the car is reporting 56.4 MPG since the DPF drill-out, so is the DPF really the way to go to save the planet? Pre-drill out the car was struggling to return 43 MPG.

While I'm on, is there an easy way to kill the car alarm? Is it possible to just unplug it or will go off and need dropping in a bucket of water...? :D

Thanks!

It's a bit more complicated than plugging in a cable - you need to download the map file from your cars ECU, modify that file so that the car no longer has DPF and EGR functions, as well as making sure the engine runs as it should, then uploading the modified file onto the ECU.

Then the EGR and DPF ought to be blanked or removed.

A Galetto or KWP2000+ will suffice to download and upload the files, but modifying it requires some detailed know-how and specific equipment/software.

Not worried about uploading / modding and saving back to the ECU, KWP2000 looks like the way to go, any recommendations for software? I've downloaded ECUSafe but my virus checker goes nuts and won't let it run.

Yay, the car is still running! Slight leak from the exhaust side of the turbo but I'm not taking the thing apart again. :( (I did notice the new cartridge didn't allow the casing to line up perfectly but I carried on).

Still need to find that alarm siren and disconnect it!

144k miles, blowing some soot and cooling fan still runs on for ten minutes when I park but I'm getting 58mpg!

Ecu safe does not work on 1.6 hdi bdm is also the only reliable way to map ecu. Obd programming has a high risk of bricking unit

quick update if anyone is interested. Stupidly, I re-used the gasket on the hot side of the turbo, I assumed the gasket was meant to be flat. This side blows like mad and is covering the whole engine in soot! I have ordered a new gasket which is not flat but has a slight bend in it, I will fit this at the weekend.
Once the turbo is leak-free, the VNT will need setting up, is this something a moron can do (i.e. me)?

I have also downloaded the ECU map with a Galletto cable and looked at it with WINols software. Does anyone know the hexcode for the EGR and DPF so I can find them?
I'm a bit scared about bricking the ECU, is there anyone near Lichfield Staffordshire that could program these out for beer tokens?
:lol:
