[Warning Light] Particulate Filter
#1
Hi all. After  some advice please. Particulate filter risk of clogging warning message on 2011 Berlingo Multispace. As I think it has Eloys system would it be ok to put a diesel addittive in fuel tank to try and clear with also giving good run at higher speed. Thanks

I have used the additive. Supposed to make the impurity’s burn at a lower temperature . I do a lot of short runs. I do a long run at a constant speed every month which is recommended on many threads on here for that problem.

Ok. Thanks for reply. Will try. Akready been up and down dual carriageway at 60 and not cleared. Alarm and msg seems to come on when reach 40.Didn't know if would cause harm by mixing 2 different types. No I don't usually do long journeys but did do a holiday May so had really good run then.

It needs to be up to temperature and sitting at a steady 60-65 in 5th for around 20 minutes to properly complete a regen. But there may be other issues causing the "risk of blocking" message. If the Oil Ash content of the DPF is above 85%-ish and also if the engine is near to 100K miles, then this message will appear as that is the lifespan of the DPF.

Additives will not make a difference if these issues are present. The likelihood is you're over 100K and the computer will be counting down to no-start due to the level of ash stored in the DPF, it will need cleaned out, or replaced. Also, the Eolys pouch will need changed. Then both need to be recoded as "replaced" using Diagbox, (dealer lever software which many of us have) otherwise that message will never ever go away.

Thanks, but it has only done 45000 miles.  Been googling..Maybe it could be just a sensor or pouch empty or low. Would a different message come up saying empty or low do you know?, will try again to complete a regen.

It has no way of measuring the pouch contents, that is estimated based on mileage and the number of times the fuel cap has been opened and closed. A magnetic switch reads the cap opening and injects some Eolys into the tank. Each squirt is a known amount, that's how it would figure it out. The message would be "Additive Low".

There are differencial pressure sensors either end of the DPF so it can tell if the flow is bad, this can trigger the blocking message, or soot / ash level or mileage. Yours could be a combination of those issues.

45k is half way, but if it's always been used on short local running, then the ash level may be very high because of that, long before the 100k arbitrary mileage limit.

Think I will have to have diagnostics on it as not cleared but another thing I have noticed is on central screen a car symbol with arrow pointing forward and only showing low mph speed. From 8/12 mph only. Do you happen to know why this is. Thanks

Average speed? You know you can change what's displayed up there, with the Comp button on the end of the wiper stalk? Also the DISP button on the stereo if I remember right (not had a Berlingo for a year, memory of little things fade. Next one is due this weekend, can't wait)

The little car with the arrow and speed, check your handbook, average speed I reckon it'll be.
