Anti-pollution and engine light

[gilessav]

Hi Guys,

Went to start car today and have out the blue the engine management light and anti-pollution message.

Car drives fine with no power loss or other obvious symptoms. I've booked in for local garage to read the codes tomorrow but undertsand that the message seems to be a general one for many potential issues.

Being that i've driven 50 miles with no obvious fault is it likely to be ok to keep using it? Any thoughts on possible issues?

Strangely coincides with first cold morning this am and a new batch of Asda petrol 10 miles before the light sprung up Any suggestions on anything i can do to check before the garage get it, can the ECU be reset somehow (remove battery etc?) to check if it comes back?

Thanks for any help

You've got a 2.0l petrol haven't you?

You're right to get the codes read. You're also right that the antipollution message seems to be the one that pug use for anything that's not specific....

You might want to give it a couple of days to see if it goes away in it's own, could be something damp etc...

Thanks for thr rapid response

I was thinking of liberally spraying the various connections with WD40 or similar as it has rained alot over the weekend and alot of condensation around this am.

I'll get the codes read as i assume they will stay in the memory until cleared/reset. If i was to disconnect the battery as suggested (30 mins?) to reset the ECU would this be worth doing or would it clear the codes and poss freeze my radio which i have no code for? i'm hoping as its driving ok and no limp home mode that it may be something small. Hoping the CAT is not toast or similar

2.0 Petrol as you say with 93k miles 01 plate. I read some horror story about fluids and filters costing the earth but is this deisel related only? Could new tank of dirty fuel cause these types of issues? engine light stay lit, antipollution message flashes up once with one beep when start car and then doesn't flash again.

Typical it was the one morning that i really needed the car not to play up! only had it a month and its the wifes

It's not playing up, when it doesn't work at all, that's when it's playing up Just think of the odd message and light as a characteristic .

Mine's been doing this for about 6 weeks now, eventually took it to the garage last week and he's diagnosed a faulty sensor on the exhaust, pre-cat. It's going to be changed tomorrow. But as you say it could be pretty much anything.

Last time it did it and din't go away on it's own it was the EGR valve.

The other thing I've experienced in the past is the odd message the day after doing motorway miles in torrential rain, something getting wet 'cos after a dry run the next day it always goes out.

I don't think the half hour with the battery disconnected works, I think the only way to clear the codes is to use a code reader.

I doubt it's fuel related, more likely to be a dodgy egr / sensor / wiring / damp problem... in other words, could be anything!

Don't worry about your radio, it doesn't have a code, it's programmed to only talk to your car.

Thanks again for the help. I'll see what the reader comes back with, i'm suspecting a faulty sensor of some sort although car runs fine currently.

If Its all a bit vague then i might try some injector cleaner or see if a good drying out fixes it. Not sure its character adding, had a 2.1TD for 2 years and no issues and twice the mileage

Well car was hooked up to the diagnostic today and no codes were identified. The antipollution warning and engine light were cleared and did not repeat upon test driving. Garage has suggested i leave it a week and if it comes back take it to them again and we'll see if they can ID an issue.

Hopefully a glitch or damp somewhere but only time will tell.

I'll post back if it re-occurs.

Thanks for the help so far

peugeot dont feel that since nothing is being recorded, as not being a problem. thats what I found when it happened to me. it comes and goes when it feels like it. no power loss, so just keep on driving.

I replaced the cat on my 2000 2.0 petrol and after a couple of days the eng man light came on.I also replaced the lambda sensors and the rest of the exhaust system at the same time,I was hoping for fit and forget,but that was not to be.After getting code read,the diagnosis was ageing cat.I would like to change the cat again but have decided not to bother as I have had two middle and two back boxes on(first middle fell to bits inside blocking the system,did this bugger the cat? and second middle was a really poor fit and wouldnt stop blowing).So I now have an exhaust that doesnt blow so Im enjoying the warm glow from the eng man light on a regular basis
Moral of the story is dont fit anything other than a Bosal exhaust system(if keeping standard)and dont fit a cheap cat.I should have know better really as I work and sell parts for a northen based motor factor.
O well keep smiling....

I got in my car, (2.0l 01), yesterday and had this Antipollution fault come up. The message would appear in tandem with the engine light coming on and beeping. The engine was running pretty lumpy as well. I figured it was due to damp or something so left the car to warm up. After running it up to temp it was still a bit lumpy but decided to take it on a short run to see if it cleared. The car was pretty sluggish, but I managed to get it to a petrol station about three miles away. I turned the car off and put £20 worth of petrol in, then off I went. The fault code and beeping were still there but the car seemed to be running better. I think this was because I turned it off and something reset, not cos I put some more petrol in it.
I then drove the car 160 miles with no problems, apart from the constant message and beeping. Turned the car off for about half an hour then when I got back in the beeping was no more and the intermittent message had gone, although the engine light now stays on constantly.

The only issues I have had with this car have been electrical ones due to damp weather or rain. I'm going to check the connections to the EGR though, as I may have disturbed them going over the recent snow and ice.

The fault went away on it's own. I got in the car the next day and it flashed up once, then I never saw it again. I suspect it was just damp wiring or something.
