Re: Recommendation .
The DPFs are very reliable in my opinion, and I've never had a problem with any of mine. Just ensure the DPF additive is checked at 80k miles and the every 20k miles thereafter and topped up if necessary and ensure the engine ECU has the additive counter reset.
As far as the DPF goes, about 100k-120k+ miles shouldn't be an issue for a DPF before it reaches end of service life and needs a thorough clean. Off vehicle is best and I'd recommend having it professionally done so as to reduce the risk of damaging the filter ceramics that hold it in place.

Re: Recommendation .
Thanks for the reply, how do I check the additive and where is the tank , this car is only used for short trips only the odd occasion it is used on a motorway . Thought of putting Liqui Moly 2146 in but a warning about using that with a Citroen.(2005, 1.6, 84,000 )

Re: Recommendation .
You really don't want to put anything else in the fuel tank - the assisted regeneration system generally works well without the need for anything else except a good run once a month. Certainly do not put anything other than the correct specific type of Eolys solution into the additive tank or that cold be the end of it.
The additive fluid level is not physically measured. It is estimated from the quantity added when it left the factory, against fuel added since and when it gets to a certain estimated level it will flag a warning up that it needs topping up. This can be done by the dealer as it needs the additive ECU resetting. Bear in mind that some MK II C5s had a separate additive ECU and these could fail to reset necessitating a new one (though not too expensive).
If it is working fine now then leave it for the present. How many miles has it done? If about 80k miles, then the additive level should ideally be topped up and the ECU reset, which needs a suitable professional level diagnostic tool. Or just leave it to Citroen to do for you if you don't want the hassle and potential complication.

Re: Recommendation .
OK, was just going to order some cleaner ! Is the additive expensive or is there a cheaper option ? I had the engine light come on the other day whilst driving to the airport and the car stopped but restarted and run fine since, that is when I started reading about Blocked DPF's ! Still trying to clear the light without using my Autel, so hot here to do anything !

Re: Recommendation .
Additive is generally about £25 a litre - but it is imperative that you get the correct type for your vehicle - there are different types available depending on build date. Failure to do so can result in destruction of the additive pump.
Additive only needs to be topped up once or twice in the vehicle's lifetime generally speaking, so should be considered part of the cost of keeping harmful particulate matter out of the air - which is very harmful - especially for kids and their developing lungs.
The engine light can mean many things - did you get a message or not? You may have another totally separate issue - or the extreme heat at present may be a factor, so a diagnostic would help.

Re: Recommendation .
Have you taken it to diagnostics to see which codes pop up? Since you got that message it logged some fault for sure.

Re: Recommendation .
I had/have same issue with my C8. I've found putting Redex DPF cleaner in the fuel tank will eliminate the warning light. I filled up again once it got to 35miles left before empty, no dpf cleaner added, EML back on. Try adding it, see what happens.

Yes I ask the stupid questions, because normally it is that simple.

Re: Recommendation .
My car is working perfectly without putting dpf cleaner but shows the EML. If I put dpf cleaner in when I fuel up then the light disappears and so does the computer/screen message disappears.
