Hello again.

So my troublesome Peugeot 308 SW 1.6HDi 110bhp just goes from bad to worse! I've changed several parts from the turbo to boost pipes to turbo boost solenoids and still been getting random over boost codes P0243. Decided to run some proper diagnostics using Planet and the FAP app and discovered that my EGR valve and DPF have been removed from the ECU as I've not been able to get any live data at all such as last regen, soot count etc, fluid levels etc.

Driving home today, my turbo went from a light whistle to a horrible loud siren type noise. I suspect the turbo is on it's way out or the bearings have gone after 3-4 weeks of use. If the DPF has not been removed physically and been left in the car, would it cause back pressure and other issues such as the whistle on the car and now the sirens to then cause the damage on the turbo? I checked the spindle of the turbo and it does seem to have a bit of play in it where as my old turbo has non at all. Could I just be unlucky and been sold a faulty turbo?

Any ideas or pointers would be amazing.

Thanks in advance,

Ben

Overboost can happen with a poor remap from the sound of it your turbo had died. Easy check is to take inlet pipe of turbo and see if you any significant play it the turbine shaft.

A word of warning the blades can be razor sharp especially if they have been rubbing on the housing

Thanks for the reply Windy. I checked the new turbo and it has play on the main shaft so I assume this is the cause of the noise. Any idea as to why this might happen? It's not even a month old :(

Likelyhood is the new turbo was fitted without fitting a new oil feed pipe. If its not fitted with a new one, the oil strainer on the old pipe will be blocked and starving the turbo of oil, causing it to fail prematurely.

Big write-up here: Blown Turbo - I think

I replaced the oil feed pipe and changed the oil when the turbo was replaced. The issue was the DPF wasn’t cleaned out and was totally blocked up. Despite being removed from the ECU. Thanks for all the advise and tips, finally solved the issues. Just need a new turbo now 😞

Ben,what symptoms did the blocked DPF throw up.

Hi Wilf. After replacing so much stuff, it still kept throwing P0243 overboost error code ( then limp mode ) but this was only when pushing the engine in higher gears like overtaking a car. Around town driving didn’t seem to bother it. Really annoying issue tbh. We didn’t suspect the dpf as I asked my mechanic to check the dpf when it had its cam belt changed and he said it was normal and the soot content was low. He couldn’t have read that as I tried to read it with planet and my FAP app and I got no readings at all as the dpf, egr valve and additive tank had been mapped out of the ecu. Had he told the truth about no re gen’s etc I would have checked it earlier and saved not blowing my turbo :( We live and learn! The car runs lovely now, with a new turbo fitted of course :)

Thats a heap of grief for sure. I don't have any boost codes,or indeed ANY codes,but the thing starts lurching and running out of power at about the same point in my daily journey. Once I manage to drive "through" this,it runs sweetly for the next couple of hundred KM...I am leaning towards a Blocked DPF,but not sure enough !

From what you describe it sounds like your car needs a dpf re gen. Can you check when it was last done by planet Peugeot or the fap app? If not take it for blast down the motorway and use some dpf cleaner and that should resolve it. I would invest in planet Peugeot or the fap app plus elm BT adaptor
so you can check the status of your dpf and last regen , soot count etc as they can give you lots of issues if it’s still active in your car. The FAP app is the cheaper route :)

Let us know if you manage to fix it?

Hey Ben,Happy 22 2U.
Interestingly the jerking/stalling issue appears to have subsided.
What I DID notice is that on my last Diesel fill (I always run brim to brim) the Eoylis dosing system operated quite significantly.
Prior to this,I had never actually heard the pump operate,today I filled again and bingo another hum from the additive pump.
Do you have any links to the FAP/ELM app. (Some confusion may be because the French translation for Diesel Particulate Filter is Filtre à Particules or FAP !) as I think that will be my next adventure.

Happy New Year also :)

Glad to hear the jerking has subsided.

The FAP app is a bit strange as you have to buy it off the Amazon store ( not the play store ) but I’ve done it and it works fine.

Here is the app link :

Here is the BT adaptor off Amazon :

If you need any help with the readings, just let me know.

Cheers,

Ben

If the DPF/EGR has been mapped out, then the Eolys system should have been mapped out too as its only job is to help with DPF regeneration. If the Eolys dosing pump is operating, then the engine ECU still thinks the DPF is present in some form, so whoever remapped it hasn't done it correctly.

Only the EGR is mapped out. DPF still in place.

No wonder its getting blocked. When i had my B7 Passat, i had that remapped. The tuner advised just mapping out the EGR and leaving the DPF in place, will cause it to soot up quicker, which is absolutely no good for town driving where a regen will not get the chance to complete.

You will need to either gut and map out the DPF, or get the EGR mapped back in.

If the DPF is mapped out, but physically still in place, it needs gutting. Otherwise there is no regen taking place to unblock it.

I'm leaning towards option a) Gut and map out !!

I gutted mine recently :) It made a big difference as my DPF was actually clogged up! My EGR, Eloys tank and DPF were already mapped out though….
