406hdi exec anti pollution system defective

the engine management light illuminates and the
display shows "anti pollution system defective"
the enigine also cuts out when put under load ie
during acceleration

any suggestions!

 

Get the fuel filter checked for metal particles. I had the same symptoms
when the fuel lift pump (in the tank) started to break up. It seems to be a
common problem. Don't use it more than you have to because it will only
get worse.

 

thank bucaneer
what was the remedy
replace pump and filter?

change uplift pump and fuel filter

 

I hope my suggestion is wrong because it can work out expensive. The
Peugeot recommended method is to replace everything from (and including) the
tank to the injectors and I was quoted £3,500. Fortunately a relative who
works on diesels did much what you suggest, i.e. replace pump, flush out to
filter and replace filter. Even then it was over £800 as the pump alone is
about £500, I have seen other posts where people paid around £800 as well..
If this does prove to be your problem it depends mainly on whether the
filter has been compromised as to how much needs to be done, certainly if it
has reached the high pressure pump and injectors you will have a headache,
but I definitely recommend a good local mechanic over a dealer. Like I
said, I hope I am wrong.

 

Hi,

It's a similar price here, in France for such operations. I know a guy who
had the same problem on a 307 HDi (he complained about a lack of
performance, and they found metal bits into fuel filter housing), replaced
all the circuit two or three months ago, and although car was far out of
warranty (yr 2001 307, 1-year warranty), the injection system swap was free,
Peugeot paid for it all.
