Engine anti-pollution system defective

[mackie1234]

I have had a look around before posting this topic but couldn't really find one that resembles my problem so here it goes...

I had a blowing exhaust that was needing a repair, the car is a taxi and i didnt really have the time to get round to it at that point so i let it run for a few weeks blowing (not a serious blowing) during a saturday nightshift a couple of weeks ago i had to do an emergency stop as some drunk jumping out infront of me, thats when my management light came on and the "Engine anti-pollution system defective" came on, i'm no mechanic so was therefore inclined to drive straight home n get it checked on the monday morning, however i was about 15 miles from home and upon heading home there was no smoke or no limp home mode or any other power issues so i decided it seemed ok to work on i was presuming it's probably because the exhaust was blowing anyways or some sensor fault due to the emergency stop.

Anyways i'm a few weeks down the line have had the exhaust fixed and the light remained on so i took it to a garage to get the code read, no fault codes we're coming up on the computer, so i took it to a second garage and again no fault codes shown, meanwhile the car is driving fine no smoke or any other visiable faults it's well maintained and serviced between every 10-12 thousand, but the light remains, i dont really wanna take it to the peugeot dealer to be ripped off so does anyone have any idea's any other things i could try or what it could be? i'm not sure if it has one of they particulation filters on the exhaust? Or is there anyone on here local to Livingston/Edinburgh with the pp2000 i could maybe meet up with? Or should i try manually resetting the ecu by removing the battery?

soz about the long story just wanted to explain it as it happened, any help greatly appreciated

The car is a 2.0 hdi 90's on a 53 plate with 133 miles on the clock

Well, the good news is you dont have a particulate filter.

The bad news is there's no obvious way of tracking your problem down without diagnosis.

I'm thinking the exhaust leak is probably unrelated & your problem seems to have been down to the emergency stop, i.e. something got disturbed. Chances are, if it drives OK, you.ve nothing to worry about.

If it's not been done recently. I'd check the fuel filter, otherwise keep your eyes open for other clues.

It was serviced little over a month ago, i will keep my eye out and see whatelse is playing up a bit, do u or anyone else who is anyone on here is selling a pp2000? i do own a autel code reader but that appear's to be just not up to the job
