#1: Anti-Pollution Fault Author: declfc, Posted: Tue Nov 11, 2014 12:32 pm ---- Hello, I was wondering if I could get some advice.
My car Peugeot 206 HDi GTi 110 – 111000 Miles
Last week I was driving home from work and my engine management light came on with the alarm “Anti-Pollution Fault” on the display screen. The car went into “limp” mode and I very slowly drove it home.
I booked it into a garage for them to take a look at. But 48 hours later I got in it and went to drive it to the garage and the fault had gone, no alarm in the display and engine management light was off. Car drove fine.
I took it to the garage the put it on the diagnostics and the only fault they found was a fuel pressure one, which he cleared, charged me £40 and I went on my way!
One week later the car has done the same again. Engine management light is on and only driving in “limp” mode.
Not sure what to do now?
Any ideas?
Thanks for taking a look.

Back when I got my then brand new RC / GTi180 it went into limp mode with this message on, IIRC, day 4, then spent almost 3 weeks at the dealer/shop. Picked it up twice "fixed" - first time I got about 12km before the error returned, 2nd time only about 800m.
Apparently (what they said) it was an intermittent connection in a connector, due to one of the contact pins not being fully inserted / locked into the plug. No idea which though...

How long you had the car?
#5: Re: Anti-Pollution Fault Author: declfc, Posted: Tue Nov 11, 2014 1:16 pm ---- Just over a year.
#6: Re: Anti-Pollution Fault Author: declfc, Posted: Tue Nov 11, 2014 1:17 pm ---- It was scanned, came back with a fuel pressure fault, which the guy cleared.

What about a fix of what actually caused the error to be logged?
#8: Re: Anti-Pollution Fault Author: declfc, Posted: Tue Nov 11, 2014 1:19 pm ---- Well yeah, but what caused the error?
#9: Re: Anti-Pollution Fault Author: declfc, Posted: Tue Nov 11, 2014 3:42 pm ---- Ok its been recommended by a friend that I change the in-line fuel filter first. (had the fuel pressure fault) How does this sound?
#10: Re: Anti-Pollution Fault Author: Lecktorious, Location: ScotlandPosted: Tue Nov 11, 2014 4:52 pm ---- Questionable as the fuel filter isn't in-line!
I reckon you have a problem with the DPF system, although it will be hard to tell exactly where until the fault returns.
#11: Re: Anti-Pollution Fault Author: declfc, Posted: Tue Nov 11, 2014 5:10 pm ---- The fault is back again right now. I bought one of those OBD2 Bluetooth diagnostic scanners today but left it at work, so in the morning I will do the scan and see what faults it comes back with.
Hopefully fault will still be there in the morning.
#12: Re: Anti-Pollution Fault Author: gazza82, Location: South BucksPosted: Tue Nov 11, 2014 6:01 pm ---- if that reads it ... OBD2 might not work depending on age of car ...
#13: Re: Anti-Pollution Fault Author: 206HdiGti, Posted: Wed Nov 12, 2014 6:04 am ---- I had my DPF removed and I still occasionally get the anti pollution message.
I believe there is a sensor either on or around the fuel cap area. If this isn't working properly it brings up the message, that's what I found when mine came on and we plugged it into my mate's snap-on computer.
Mine didn't go into Limp Mode though with that error message.

The fault / faults will be safely stored in the ECU memory
You would be better of getting it scanned with Peugeot Planet.
#15: Re: Anti-Pollution Fault Author: pro_steve, Location: BristolPosted: Thu Nov 13, 2014 4:37 am ---- Anti pollution covers just about everything. AFter having the codes cleared last time when you scan this time around you'll know that whatever is there is the current fault.
If there is a fuel system fault then you will need to sort this out. You'll need to do some live diagnostics under load to figure out if the fuel system is under pressurising or over pressurising. Take the pressure regulator out of the pump and give this a clean, usually this will cause faults like this, or potentially a dodgy remap if you've had one done at all?
