Peugeot 307 2.0 HDi RHR 2006 - DPF fault - Fixed #

Posted by Shane Gray on July 7, 2012, 7:04 pm

Year of Manufacture *: 2006
Engine Size and Code *: 2000 hid rhr
( Optional ) Scanner Used: Mach vci

Hi,
I have got a Peugeot 307 2lt hdi with engine code RHR.
Eml on and I have read fault code which is fuel additive fault,
The engine is idling rough and there is a lot of black/ blue smoke out of exhaust , I have filled the additive tank which was only half full, I tried to force a dpf regen but it keeps failing.
I have not done much with these systems so any help will be appreciated, got a feeling it could be the fuel additive ecu!
Thanks Shane

check the management system for faults shane, if there are any present the system wont allow you to do a forced regen. sounds like you might have an injector on its way out.

Hi Shane,

Can you let me know how you are connecting
>>> The engine is idling rough and there is a lot of black/ blue smoke out of exhaust <<<
with a additive ECU fault ?

Hi all,
I read engine ecu and the only code is fuel additive system fault. I'm connected using a Mach vci by mac tools, I find it pretty good on must cars.
It seems as if the car is trying to regen all the time but can't do it, the smoke from exhaust smells like it does when regens .

Hello Shane, I don't think that was what Mark was asking.

Sorry what do you mean?
Can't connect through additive ecu no comms only engine ecu.
Are my still missing something?

I think Mark is trying to find out how you are linking the poor running with a additive ECU fault. Maybe I read it wrong but I'm sure one of us will be corrected in due course. Best regards, Alan.

I'm with Alan.

I can understand you reading the engine ECU and finding an additive fault code stored.

I am failing to see the connection with the black smoke and the poor running at idle.

I was just asking how you joined the dots up, maybe you have seen the PDS reading and have worked out the pressure is so great that the engine can not get a fresh gulp of air?

Regards.

I dont suspect this is anything to do with the running fault but if you cannot communicate with the additive ECU how did you carry out a counter reset?. Its not just a case of filling these additive tanks there is a process to go through afterwards. Many posts regarding this on the forum.

Hi again,
The EML came on and the engine started to idle roughly, I just assumed it was connected as there are no other fault codes. I'm aware of the counter reset procedure and with no comms to additive ecu wandering whether that's the fault?
Any idea what the DPF pressure difference should be on live data?
thanks shane

Hi again,
Just a quick update it seems to be an egr fault i had a nice man ring me from the forum and give me some tips, I looked at live data and the air flow is not right with the egr.
Sorry mark I have read your reply again and it makes sense now, I had tunnel vision and was only thinking about DPF/additve. (what a plonker!)
