Did the 180 map a few weeks ago now. Defap and de egr. Last night my dpf warning and limp dick mode kicked in again. It happened to anyone else?
Ive just tried the 200 map to see if i see a difference to make sure maps are uploading. But figure a quick ask on here may be worth a shot to

A map cannot delete itself, or the car would not run What can happen is that the map is not suitable for the works that have taken place.
Did you get the map from a reputable source and was it a modified one from your original?

When you say, "dpf warning", do you mean the filter blocked warning light, 'Unblock diesel filter' message, or just 'Antipollution Fault'?

Anti pollution fault. And it was a very good source i got them off.

A/P fault just means any engine ecu fault, not necessarily anything to do with the dpf.

The usual culprit is overboost, typically caused by a vacuum leak. This thread from the coupe forum is the best guide I know of: http://www.406coupeclub.org/PHPBB3/view ... 82&t=35570

Agreed - the 'Aunty Pollution' is a generic term for 'Somethings wrong but I carn't be arsed to pinpoint it' so a session with PP2000 is on the cards.

Turbo EV or the swirl diaphragm is the most likely suspects....

Anti-pollution fault get's flaged up if you run it out of Diesel , but reset's it's self after a couple of start stop's

im thinking the swirl thing then. didnt get chance to check that.
i put the 200 map on car to make sure the maps were taking which i can say defo is. so have put the 180 map back on ( i didnt like how much fuel it was using)

i will get a pp session sorted soon. i want to activate the total closure system anyway lol

thank you for the help and advice

Just a thought, but I have known computer files corrupt for various reasons, so see no reason why a map should not fail. The only thing I am not sure of is whether a new map deletes the old one, replacing it entirely, or just updates it, in which case it could default back to the original, depending on the reason for its failure.

The confusion here is caused by PSA's rediculous fault description, (causing the OP to think he has a dpf problem), when in reality it's only telling him it has detected an unspecified engine ecu fault.

Sorry, I think the total closure only works on the Coupes - it wouldn't work on my 2004 Exec, but most of the other options on PP2000 worked fine.

mine is a coupe mr magic.

the apf has popped up 2 or 3 times now. notice it when i say drop a gear and give it some (coming out of a 40 mpg speed restriction and back up to 70 ish)
i also get whistle noise all the time when driving or when i let go of the accelorator. so guessing it is more directed at a boost leak.
another thing i have noiced is say 4th gear, doing around 30/40 when i then floor it, it can be a little hesitant then boosts. again me thinking towards a leak
