406 LX Anti Pollution Fault

hello I am peugeot fan;- I am now begining to hate them as a result of the dealers they are killing this brand and the company does not seem to care.

I had a 1983 205GL great car never gave trouble and now I brought a

406LX (2001). few months back the dreaded engin management light came on with the reading "Anti Polluition Fault" took in to dealer could not diagnose but charges me in total =A350 for pluging in the machine!!. said it could be something to do with the "secondary air intake system" Then I discoved that the exhaust has a bolw out changed the whole system including the both the O2 sensors. Now the light comes on and off the car runs fine???!!!??? very frustrating wonder if any one else has had this problem I have so changed the spark plugs oil as well. thanks

Welcome to the club. I own a VW Golf 2001 with a similar problem. A 80 euro cleaning job had no effect. The dealer says there's nothing wrong with the actual emissions. He is earnest to tell me that he can try to replace parts but that he cannot guarantee that this will solve the problem. My solution: a piece of black tape over the light. Fortunately there are still indicators for oil pressure and coolant temperature and the car runs OK in every other aspect.

A friend of mine had the same kind of problem with his Volvo. My sister evenually bougth a Skoda after her Peugeot 206 frequently simply did not start and the dealer was not able to find the cause. I also heard about these kinds of problems with a Fiat Stilo. I think it's all about software. Microsoft is not the only one that makes a mess of it. Garage people do not understand what they are doing when dealing with the motor management system. They simply follow outlined routes that are sometimes quite irelevant. It's time the manufacturers find a way so that the involved risks are better spread over customers. (I had also a 1300 euro misfortune of damaged valves due to a timebelt problem, in spite of all prescribed maintenance.) I noticed that e.g. Honda and Toyota owners were more statisfied, but I am afraid that these kinds of problems are very common nowadays. For the time being, my next car will probably a Honda or a Toyota.

I've had that happen with a Fiat Seicento, also similar on Renault Megane Scenic. In both cases it was a similar sensor. RPM sensor on the Fiat, TDC sensor on the Renault. Both do a similar job - they won't start as the computer can't sense what speed the engine is turning over at in order to engage the choke/fuel.

Thank you for both the replies, I think this is a joke the whole point of having diagnostic device is to find the problem quick it obviously seems to be doing the opposite!!!??!!

I think as per peugeot I thinkthe owners of models with these problems should get to gether a send a petition to them, might wake them up. wonder why they cannot make cars, which when a light comes up means their is something seriously wrong!!

Hi

I had a citroen picasso some time ago with a similar problem. Garage never solved it and it went away of it's own accord. There is a web site which discusses this problem in greater depth

formatting link
Whilst it is not the same car it may have commonality of parts / design and there is a link halfway down the page to a technical discussion document from Citroen about lambda sensors.

Hope it hels.

Thank you for all the good advice.

I think the problem was (hopefully) with the lambda sensors I replaced both when changing the exhaust system as no voltage was coming to them and cleared the faults. Lo behold the light came on again, so i hooked it up for the million time into a digagnostic machine!!! if I had gone to a peugeot dealer I would not have money to eat but my local garage is very nice did it for free?? the fault code each time before this was was to do with the secondary air system this time it said it was the new and replaced lambda sensors, while they were swiching between lean and rich with out a fault.....the technician said he does not why, so ereased the fault codes and I am running car light has not come on so hopefully it would have sorted it self, funny I have spent over =A3150 now ONLY for diagnoseing this problem. Shame Peugeot SHAME!!!!

Had the same problem with my 307 2.0lt petrol. Turned out to be a faulty coil pack. Had that replaced, problem solved. Dan.

Well the light came on again.............very very frustrating..with rgs to the coil pack how can I check this Dan. The fault is registered between 2/10 seconds after I start the engine from cold in the Mornings. some times it goes away when I start again or continue to stay on for a week or so then go off come back in the day or two. good if you can give me more info.

thanks.

Sorry Laks, I wasn't the one who found my problem, the PUG mechanic did. This is what they told me it was. They said it could also be caused by bad fuel. I know....frustrating, and I'm probably not making it better either! D
