Default Anti pollution fault

Hi all

This started popping up now and again and I just knock it off on my code reader and all is fine, however now when I knock it off it comes back almost instantly

I can't work out what to look for, tried googling and it seems this fault is a common message for lots of things.

I am led to believe that the 1.4hdi model doesn't have a dpf?? So I tried to have a look at the differential partial pressure sensor behind the battery tray however it doesn't seem to be there, I have attached a photo for you, everywhere I've looked online says that's where it is but unless a previous owner has removed it if that's possible then I don't know ?

No dpf so no need for a sensor. What is the code which you keep clearing

anti-pollution message is a catch all message telling you you have a engine related fault and the limp mode confirms that but is it in limp mode? By that I mean if you are stationary and with the engine running and you push the throttle to the floor does the eng revs go full scale or does it stop below 3000rpm?

Really need diagnostic using PP2000 before going anywhere.

Not sure if any help but in this thread here P1160 pointed to the MAF being faulty https://www.peugeotforums.com/forums/...me-mode-92689/

Thanks for the reply, it limits the revs to 3000rpm, I've been trying to find solutions online and people are saying new fuel filter fixed for them, oil change, injector seals etc

I have just done the injector seals, as was chuffing, this p1160 was there before and still there after so clearly not them, I have done oil change recently but not the diesel filter

Hi mate, yes I phoned my local peugeot dealership and they wanted 125 plus vat to read the codes and then another 75 to update codes before they can read them? Not paying that and no one local to me has PP unfortunately. I will have a look at the thread you linked

You need proper diagnostics antipollution is NOT a fault it means nothing its just telling you what you already know SOMETHING is wrong

Diesels need live data readings not codes to find the real issue.

Tried unplugging the MAF as advised in the thread linked above, went real sluggish, plugged it back in and it flew like a rocket for about 5 minutes and then the fault popped up again

Peugeot are the worst place to take a car for diagnostics contrary to popular belief they do NOT know best

Messing around unplugging stuff and guessing based on other peoples similar but NOT the same issues is never going to get you anywhere.

Planet delphi or if you are really stuck snap on overpriced rubbish will all read it but you are NOT reading codes you need to look at live data to see where the problem lies
