Default Faults

Well with my 407 on the road I can see why getting used to the beeps is part of owning one 😂 . Any how I have the eml light on and it’s reporting dpf temperature sensor is playing up , so will get one on Tuesday but there are three other codes I can’t figure out ( see pics ) . Looking at the info the battery voltage is low and there is no fuel rail pressure so to me that would suggest the car is not running , could it be a ghost fault ? Also my door is saying a fault but every thing is working !

Any help peeps plz ?

Can't read the text in those pictures; this forum has a very annoying habit of resizing pictures to be uselessly small.

DPF temperature is an odd one. Never seen that before.

Everyone has the glow plug fault. Sometimes it is actually the glow plugs.

thanks dude , i didn't think it could be glow plugs as there a different code . i will run a test and see if any are gone .

the wife come back from work so i plugged in to see if any thing had changed and there were shit loads of codes .

p2564 = turbo position repeat signal
p0401 = air circut
p2032 = catalytic converter downstream temp signal
p1434 = additive system
p1471 = egr valve
p0243 = turbo pressure regulation solenoid valve control
u0122 = can-bus communications ( says about loosing communications with esp ecu )

having a look about the internet there was a site that had Peugeot codes and the p1434 actually means the cooling fan is faulty ( i dont hear it cycling on with the AC , but on actuation with diagbox it spins ) . i do need to check the vac pipes for the turbo as one had popped of when i first got the car but any tips or help for any of these codes gents ?

There is more to diagnostics than reading codes but in that list the turbo codes and the EGR code are most likely all caused by whatever is causing low boost which you most likely have due to you DPF system not working properly this would then explain the airflow related fault !

Do MORE diagnostics read live info from the DPF system check fluid levels etc check ACTUAL repeat sensor readings etc

U codes are network codes basically communication errors on its own means very little could simply be low voltage brought it on even stalling the car can do it.

well a weekend off and two days on the car .... loosing the will to live !

found the additive tank empty ( but no codes listed ) so filled it up and it took 3 lt , relearned it in diag box . then decided to look at P1412 catalytic converter downstream temperature signal , it has 5v on one side and is stuck at 98' so fitted a new one , still no change ! also now keep loosing esp communications to engine ecu , removed multi plug on abs pump and all pins are spotless . seem to have a lot of communication codes starting to appear such as p1693 , u0122 , u2003

Post up the DATA from your DPF

Network codes will be logged if you turn on and off alot or if battery voltage goes low long cranking will also do it as i say dont worry too much about them for now

i had my pug 208 diagnosed with P1434 (additive pump) and P1445 (dpf saturation) by local peugeot dealer. needless to say i was told to replace both.

took the dpf out to see whats wrong and it was fine other than fluid saturation. had it cleaned anyway.

now struggling with P1434. fluid level is fine.

did you have any codes/messages about motor not working?
do you know if there a test procedure for testing the motor?

cheers
