DPF question

[Bhavesh]

Cleaned out the rubber pipes with an air line and yes it was the B28/8 only.

Thank you

I have had the same problems regularly when I had a diesel cars, short distance was the issue, getting the engine exhaust hot and then staying in lower gears to run a steady 2500-3000 revs for at least 15minutes always sorted it, but I got sick of it and went back to petrol cars(no dpf issues now), there is no point in having a diesel if you don't do long runs.

Hi there. What do you would be an adequate daily run in order to keep dpf clean? And if one uses for shorter journeys is it not just a case of more frequent maintenance? Thanks

I would say the car needs to get hot so the regen can take place. If you stop in the middle of one, it will begin again next time you start and the engine is hot. Most of our journeys are short and we have no issues.

I have had hair pulling troubles with the DPF but now I know what to look for I am confident that short runs are not an issue, as long as the engine gets hot. The DPF will probably fill up quicker with ash and either need to be cleaned out (which I have done) or replaced.

I can't imagine a situation where I'd ever drive at over 2,500 for 20 minutes. Even at 80mph my revs are about 2K.




Try using a DPF cleaner. My local DPF specialist (Avon Tuning) recommended Forte https://www.amazon.co.uk/Forte-DPF-Cleaner-Regenerator-400ml/dp/B0061ATRK2/ref=sr_1_1?crid=4BTS0K9V51FT

you could always use a higher gear to rise the revs ,

Lower gear

A solid run of at least 20-30 minutes every 300 miles will keep it going. Speed and revs are pretty irrelevant with todays DPF's as they can regen at near idle (they raise it themselves). So even city driving can regen without issues. You just need to give it time to get up to temperature and complete.

When I had the Kia, I read on a Kia owners forum that use premium fuels will help prevent DPF clogging on low-annual-mileage cars.

For the 6 years and 6,000 miles that we had the Kia I have only ever used premium fuels in it and had no DPF (or other) issues.

Said that... it is also possible that the Kia is just more reliable than the Merc and the fuel had nothing to do with it.... I don't know. And I no longer have a Diesel car anyway.

Yeah, I know that but that means you would have to know when the DPF regen needs to be done to deliberately drive in a lower gear, and be in a situation when you can do 20 miles or so at that RPM

I would say 30 minutes from when the engine is at operating temperature, so probably 45 min from start up, normal regen occurs when at motorway speeds.
The forced regen needs the engine hot and revs at over 2500 rpm steady, so a lower gear selected in manual mode on autos.

On my 2012 ML250 W166, I had Refill Ad Blue alert,
When I filled tank with 20 litre Adblue then the " No Engine start XXX miles" Warning came up.
EML light is on.
On the service menu it says AdBlue tank is full.

I was advised that the software update will clear the problem.
I can see lots information on Vehicle Data menu of my car but don't know what it means.

How can I check what is the current software version on my car and whether it is the latest one or not?​

The Diagnosis with icarsoft MB V2.0 shows,
