Dpf issue

[Jebby80]

Hi everyone,

Please be kind this is my first post.

I have a Citroen ds5 63 plate dsport 2.0 diesel. Up to now it had been great it’s only covered 50000 miles.

A few weeks ago I got the dreaded dpf warning light so tried to do the regen which cleared the service light, then the next day it went into limp mode with the engine warning light coming on as well as the dpf one. I had it cleaned then had a forced regen done on the computer which cleared everything. It was great for 80 miles then the dpf light came on which I did a regen myself and cleared the service light. The next day it went into limp mode again and I’m back to square one and the computer won’t even do a regen?? Can anyone help me? What could I do next to get these faults gone once and for all? Cheers

Hi

Have you considered that the filter may be at end of life? How many miles has it done?

DPFs have a finite life and although they may be deep cleaned at some stage, they will not last forever as the Cerine particles in the additive fluid cannot be burnt off and these ultimately clog the filter along with other engine deposits.

When the filter is blocked at a certain percentage, then no amount of regeneration will fix it and continued attempts will put wear on your engine components - as forced regeneration is not recommended unless there is no alternative for this reason.

You need to get it on Diagbox and read off the fault codes and post them up here along with your VIN.

Shame seems to have disappeared how many miles will a DS5 last before requiring an additive top up< would have thought (hoped!) it should be nearer 100k rather than 50K

That's a difficult one Tony, as far as the additive goes because they don't fill the additive tanks up at the factory when new. In the case of the DS5 with the DW10CTED4 engine, they only fill the tank with 1.35 litres..... so when the warning for low level does come on, it will probably best to get a 3 litre top up kit and be done with it.

The Euro 5 Emission standards set objectives for the life extension of pollution checking devices to 160k Km (99.4k Miles).

As for the filter clogging warnings, this can come on as a reminder to drive the car for 3 minutes at a speed greater than 50 km, which should clear the message - but this needs to be done within 100kms of the warning, or continued clogging of the filter will occur and trigger the actual filter clogged and further anti pollution messages.

HI, I'm new here and have been scouring threads related to this topic before posting!

I have a Dispatch Combi 2012, 98K on the clock. I had the risk of filter clogging warning and the engine warning light on.

Had it checked out at a citroen dealer and was diagnosed fault P1442- 'additive system level low or adding impossible'.

They recommend to replace the pump and tank at a cost of £672 (kerchang!) However, since then, I drove in 4th gear, over 25000 revs for about 9 miles and ..after leaving van for nearly 5 days, Ive driven it today and no warning light or screen message appears.

Do you think this is the last of it, or will i get another fault reading the same ?

Any advise or comments would be greatly appreciated , Thanks
