Hi, welcome to the forum & the Kia Carens ownership club!


You have found 1 of the few problems this make/model suffer from. The warning light signifies an "emission" fault, this can manifest itself in several ways. There is an ECU upgrade which does help but doesn't solve the problem completely. You can have the EGR valve replaced, again a help but not a permanent fix. Last but not least you can have the DPF (diesel particulate filter) thoroughly cleaned. This is not something all dealers do as a matter of course, it has to be asked for normally.



The clean is quite simple & involves nothing more than time. Of course this should be done by a dealer but I am informed that KIA UK no longer cover this under their warranty, something I'm in dialogue with them about, at my next service I'm going to have my private mechanic do the job, downtime is very costly in my trade!




I'd ask for the exact fault code explanation, is it uneven pressure at either end of the dpf? Or something else?



I hope you can enjoy the car for what it is, faults are irritating to say the least but in general this make/model seem to bea lot less troublesome then many others!



Mark.

im lucky with my carens as i dont have a dpf but 1 thing i do believe is that the cat has to reach a very high temp to burn the emissions this can only be done by running for a considerable time at speed or revs to get the cat hot thus burning gasses and passing the correct signals to oxy censors and ecu its not just kia that have a problem there are reports in auto express of it being a problem with a quality german marque costing upwards of £1500 a time,to put right, inside the m25 being most especially a problem area as its not easy to get the cat hot

thanks charlie.im just outside the m25 and tend to do lots of short journeys.average 18 mph and also very low mpg..as low as 24.on clear runs up to 42.also have reported to dealer of burning smell from exhaust area,and was told this was proberbly to do with engine/cat de-sooting its self?so what youve said makes sense.it may well be that if the problem persists then the carens is not suitable for my driving enviroment

The burning smell is the DPF doing a "regeneration", in simple terms the exhaust burning the build up of soot normally caused by lots of stop start journeys, it seems we both do lots of those! A tip for you: Just before you switch off the engine open the door, if you can feel a regeneration in progress try to run the car for 5 mins to let it finish, I've found this to be helpful & am getting less "grief" now.


24mpg is about right on urban cycle for an auto, my manual doesn't do much more but then mine works a lot harder, lots of idling (especially in this weather!) & rarely gets switched off for hours at a time.



As I said before, ask for the exact fault code description & if you need any advice on the dpf clean,let me know, your dealer should be aware of how to do it though!

Please keep in touch with the Soul, it's got the engine that will be in the Carens so am interested, my initial reservation is 124bhp from a 1.6 will be stretching things too far, some of the guys with the new Octavias are reporting problems when fully laden pulling away & Brighton is a hilly city!


Good luck, what colour Soul did you get? I love the black with black wheels, very gangsterish lol.
