Hiya guys,

I have a Mazda 6 turbo diesel and the DPF light and management light has come on, its a high miler 85k on a 57 plate, I have run over it 2000 rpm for quite a few miles and its not cleared with regeneration, and was wondering my next step with this.

I was thinking of having it taken out and the ecu reprogrammed , but its expensive at about £500 , there are quite a few people selling snakeoil that claims all sort of things. The garages are saying thousands to replace the thing.

Anyone got an alternative ? Thanks and Happy Christmas ;)

    Have they said that the DPF needs replacing? If so your options are to have it replaced, which won't be cheap, or to have it removed and the management system reprogrammed. Although this is coming in at £500 it is far cheaper than a new DPF.

    Are you a member of any Mazda forums? If not it might be worth looking for them to see if other owners have had the same issues and how they sorted it out.

    DPFs can be cleaned out but that's still around £400 - I've seen it done successfully on some of the fleet cars at work

    Your next step is to get rid of the car asap. The Mazda DPF system is a joke, they get round this by warning you in the handbook to check things, do this, do that etc. Get the oil level checked now. If it is diluted or above max there is danger of the car running on and blowing itself up.
  • Daveyjp is spot on, the best view of one of these cars is from the rear with a new owner (who didn't research first either) driving away whilst it's still running.

    The trouble is more and more diesels are being fitted with them.

    Which is why my current car has a simple petrol engine. Diesels are now for those who don't pick up the tab when it all goes wrong.
  • Can't get rid of it I am afraid so I am stuck with it, it has been serviced regularly by mazda and the next one is in 2500 miles, the oil is fine and not diluted in any way, guess I will have to get the thing removed to solve the problem, the car is perfect by the way I love mazdas and have never had any problems with them, well until now!

    Have heard with the vauxhall's if you take it out and jet wash it does the job.

    maybe would work for you.

    worth a try before spending £500.

    All new diesels have them now.
  • if your handy with a set of spanners, and have a pressure washer handy, and a dry garage or car port get it up on axle stands, take the thing off, (disconnect battery) and wash it out. usually you have to top up with elloys fluid, these usually a filler funnel in or around the rear arches (tyre removal required) top it back up. put all back together and do a 30 min long run for the ecu to relurn. EML should stay off.

    then save up get the EGR valve,DPF removed AND ecu reprogramed
