Hi all, I have a 1.4 Peugeot 206 glx 2003. I have had emissions problems with the car since September 2010 - that is when the engine fault light appeared. At the 2010 MOT new sensors were fitted....the light came back on a few weeks later. At the 2011 I was informed that they really had to try hard to get the car through the emissions test and after a long period the testers eventually did but that a new cat convertor is probably on the cards. For the 2012 MOT I did have a new cat convertor fitted and guess what....after a few weeks that engine warning light came on again. Following the new cat convertor a few weeks later the car required a new end exhaust section and then a few weeks later after that the car required a middle exhaust section.
2013 MOT - after reading the MOT test sheet I saw that the first round of emissions was a fail but the second round passed.
Now we are at 2014 and my lovely car has failed on the emissions....I was told 'you probably need a new cat convertor' - but I had a new one fitted by you only 2 years ago.
Is this on-going emissions problem possibly down to a fault cat convertor or do I have to accept that I am going to need another new one so soon?
Thank you in advance for your reply

What sort of mileage / driving are you doing. The reason I ask is if it is only short local trips then the cat doesn't get hot enough to function properly.
Most manufacturer will only guarantee a cat for 12 months.
I suggest getting the EML code read when it comes on, it may point to a different fault.

You are right - I actually only do short trips in the week - the train station and back and maybe a little further at the weekends - 5000 miles a year on average. So yes that does sound like it doesn't it The car is going back to the garage tomorrow so we will see what is what then. Many thanks for your advice/help.

To be honest, there are a number of factors which can be at play with Cat failure. It really depends on whether the engine is running well as you can end up clogging the Cat with oil (if it burns any) or pumping it full of unburnt fuel (if there's an issue with the general condition of the injectors/plugs/maf/HEGO etc.).
It's good drills to give the car a right old blast on a regular basis if you only do short journeys. If you don't, as has been said, the car won't ever get hot enough or worked hard enough to allow the oil or oil filter to get warm enough to work as it is designed to do in order to keep the engine in optimal condition - same with the catalytic converter.
This is the main reason why the fallacy of older low mileage cars being somehow better than high mileage is flawed, in my opinion.

I also note that after fitting the cat you later fitted a new middle section. If your exhaust middle section was leaking that means your car may have been running rich and slowly destroying your cat.
You also state that it took two runs to pass the test. This is another sign that your engine isn't running perfectly, though it may have been caused by the engine being cold, but an engine not running spot on will destroy a cat.
So the need for a new cat may not be due to cheap or poor quality item but other defects causing the engine to run incorrect fuel mix. Doing this will quickly destroy a cat.
