I too keep getting the Depollution message on my Peugeot 308 Sport so took it into a Peugeot garage and they told me the car needed a new catalytic convertor - £1300 later!!! I had one fitted, hoping that that was the problem solved and as soon as I drove home the sign came back up again - to cut a long story short the car has been back 3 times to the garage and now they are talking of stripping the engine down which i am fuming about. Does anyone have any ideas of what I should do - I dont want to spend anymore money and will never buy a Peugeot again!.. Thank you..

I do not like to criticise other garages as they may well have good reasons for renewing your cat,but I take it was put onto a relevant code reader to check your warning light,if you do a lot of town driving then this can also affect the fault you are describing and firstly i would have given the motor a good long run in low gears with high revs to get the exhaust very hot and try and burn off excess deposits in your particulate filter in your exhaust,if this failed then a forced regeneration may have been needed which involves the correct code reader again and have seen exhausts glowing red hot when this is done and should only be done on a good concrete surface as it can melt tar.If this was done at a peugeot workshop then I think they should have the correct equipment to do this and why they changed the cat i don`t know,all you can do is ask them but i know it is a very common problem,especially French cars,if you do a lot of short journeys then I would be wary of buying a motor with this system on.I wish you luck with your repair.

Thank you for replying - its so annoying when you spend so much money at a garage and they still rip you off!... Definitely not going back to that garage and hope that anothor one will be able to sort the problem out....

I know nothing about motor cars...

Either the fault light is telling about REAL pollution or the electronics that turn it on are imagining pollution that isn't there.

Garages that do MOT tests check car exhaust for pollution - a test there could tell if it's real or imaginary.

The engine management system will (should) correctly regulate the fuel /air mixture for proper combustion. Any pollutants remaining will (should) be dealt with in the exhaust system.

I fail to understand why the garage would want to strip the engine down - I wonder what they expect to find in there?

You might consider asking them - you might consider another garage.

Good luck...
