DPF Refill

Hello all,

I have been the unfortunate owner of a DPF fitted C3 over the past 3-4 years and its been nothing but problems.
I have fitted a new bag of DPF fluid, DPF pump. But unfortunately its still an absolute pos. The ECU still thinks there is 4% left in the bag so I'm forever getting a warning my particulate level is low, risk of filter clogging, etc etc. I've absolutely had enough of the car and want to sell it. But I need to somehow tell the ECU that the bag is not on 4% with 44ml remaining. I'm also not taking it to the dealers. I'd rather scrap it.

The counter needs to be reset using Lexia/Diagbox. You may find someone on the site local to you who may be able to help you, but if not you may have to bite the bullet and take it to an agent.

Alternatively you could buy your own Diagbox. Probably more than a visit to the dealers and that's if you can get it to work.

Hello

Your problem lies in only doing half a job.

This is where the professionals earn their money and get it right and do the full job.

As routemaster1 says, the ECU needs to know that the DPF/FAB bag was changed to know how much is left in there.

Otherwise the ECU thinks the bag is still (nearly) empty and issues (quite rightly) warnings that the DPF level is low.

Who knows if the ECU then limits DPF regen due to the lack of Eolys which would then risk clogging the DPF/FAP?

Well if Citroen bothered to make the car serviceable by it’s owners for a simple bag change instead of monopolising simple DIY fixes behind costly software / dealer visits, I would have done a full job.

You don’t need to be a professional to undo 3 spring loaded clips to drop a cover off. Then undo a bag again with one clip and insert the new bag.

This is why I hate modern cars with all its ECUs to stop owners from repairing their own vehicles.

Thanks for letting me know I can’t simply turn a key quarter turn and hold a button to reset it. F' me if simple fixes were made available these days.
