406 110 HDI Anti Pollution Fault

[ArLee]

Hey everyone.
Yesternight my car's [Y reg 406, 2.0L, 110 HDI] check engine light lit up and it gave antipollution fault, 2 minutes after me starting her up to go home from work.
I read few topics already posted about this fault on site mention that owner's car has gone into limp mode.
Mine isn't. She is still revving and with fault I hit 120 mph thinking it might be slightly clogged DPF and it might clear it out.
Any idea what could it be?
I don't know if it was a temporary issue that occurred for few seconds and then went away, but the fault code is still appearing, or something permanent. I started her today just to check if it is in limp mode but it wasn't. She is driving great just ever.
Would really appreciate some help and advice. Thanks!

And also can someone please tell me how much engine oil goes in 2.0 HDI? With and without new oil filter.
I don't have any manual or anything to refer. Thanks!

Without getting the fault code read, all anyone can do is guess.

The only 406 with a FAP is the 2.2 HDi, so it's nothing to do with that. (Peugeot imply that they made a 110 with a FAP, but we've never actually seen or heard of one.)

The car is in limp home mode only when the orange engine management light is lit on the dash.

It's possible to get a fault thrown up that disappears after a restart.
This happens to me sometimes when I go over a bump.

So unless the engine management light stays on after restarting, or this is happening really often, I wouldn't worry. "French electrics"

Thanks for the input.
Well check engine light [engine management light] is lit on the dash. And there is beep as well few seconds after starting the car.
I guess I will get it checked if it starts behaving erratically. Right now she is sweet as ever. Might need an oil change though.

Should take 4.5 litres, including filter change.
It can take 3 - 5 'journeys' to reset the EML if you have an intermittent fault. If it stays on longer than this, it's a 'permanent fault', but easier to diagnose.
(If you add your location someone local may offer to help)

I suspect that the only way forward with this is to get the fault codes read. As Doggy says, add your location, you never know which kindly soul is near by.

Praise the gods....
Thanks Doggy.
It was a fluke, I guess.
On my third 'journey' the check engine light turned off.
EML was on when I was on my way to work. When I started my car to come back home, EML was still on but it turned off as soon as I pulled out of the car park. So yeah...happy times!!

ive just had the same thing with mine. engine man light on dash and anti pollution in the screen display. i have changed the fuel filter (which was in a @hit state ) then i had a mate cancel the fault with a cheap fault code reader. u have to do this as the ecu will remember even if uv fixed the fault hey presto!!!! she is all good xxxxxxxxx

Had something very similar with my 2.2 HDi.

Went on for months before I got to the bottom of the problem.

Every so often the Engine Light would come on, accompanied by a beep and the multi function display would say "anti-pollution system defective". The car would also go into limp mode which was a real pain in the ar*e especially on my long journeys to Scotland.

What was weird was that after a few days, it was almost as if the car "healed" itself. The light would disappear and limp mode would be gone. However, a month or two down the line and the hole thing would happen again.

After thinking it was something serious and lots of under the hood checking, in the end I discovered it was as innocent as a split in the Vacuum hose that runs from the Turbo to the Advance on the Swirl Chamber.

So basically, check all your hoses. You'd be surprised at how something so simple could cause such problems.
