Need Advice re DPF

Just want to get an overall picture here.

Did you buy it in a main dealer?

Has it been back to a main dealer with this issue?

A main dealer wouldn't waste 5 days trying to clear a blocked DPF, you would be given a price for a new one.

You have miscalculated the length of the M50 in your post which could leave the rest of your story open to question.

Also, DPFs should not be regenerated on "country roads" as you put it and 70kph is quite slow to do this, were you doing a regeneration or did the warning just appear?

If you are doing the mileage stated on the motorway then it should be enough to passivly regenerate.

Finally, I hate when people say "the car cost €xxxxx" so it needs to be fixed.

So what how much you paid for it, there are cars way more expensive than yours that break down every day, the cost of the car has f all to do with how it will be looked at in the workshop.

Not sure what part of the country you are in. But for DPF related issues I can recommend Kennedy's Garage in Portlaw, Waterford. Look him up in YouTube. He does a lot of Mazdas, but not exclusively. If he can't sort it out then nobody can!.

Just wondering, 17 skoda superb my dpf light came on for first time last week, I took it for a 30 minute drive in lower gears, the light then went off, wondering now whether to get it checked at a garage tomoro, it should of stored a fault? Or keep driving and hope it stays off!? Any advice welcome

Ok so maybe go to a dpf cleaning place? Although I know of somebody who got that done and the dpf cracked. Thought a general mechanic would be able to advise and check codes on PC

Thanks, was hoping that's the case, do a lot of short runs and noticed radiator cooling staying on good bit after park, did a longer run in lower gear once seen light on and checked manual, must of did a regen cause light went out on way home earlier. Seems be driving fine

The DPF light just keeps coming on so we're out driving motorways trying to knock it off.

I don't blame OP for trying this, it's often touted online as the fix, but DPF regen cycles have so many dependencies on a modern car, that even if you follow the manual's advice (below), it won't necessarily work.


Even the Tucson manual is contradictory in it's own advice. It says "may stop" and "stops". The latter is much more definitive.

When the Malfunction Indicator Lamp(MIL) blinks, it may stop blinking after driving the vehicle:
• at more than 60km/h (37 mph), or
• at more than 2nd gear with 1250 ~2500 engine RPM for a certain time(for about 25 minutes).
(4-16)

The Diesel Particulate Filter (DPF) lamp stops illuminating, when the driving speed exceeds 60 km/h (37 mph), or when the engine rpm is between 1,250 and 2,500 with the gear in the 2nd position or above for approximately 25 minutes

(9-89)

is it a Mitsubishi?

Get it cut out and remapped. End of your worries.

Absolutely no need for that just yet. It's very expensive to do nowadays so a waste of money at present

Its meant to be coming in in 2027. .

If they do there will be a lot of cars in trouble

Light came on again and drove went off, slightly juddery, took it get diagnostic mechanic said it's at 16gr not too high but prefer lower, and it did a regen itself, didn't have to do a force regen. Maybe a long journey the car needs? I'm just doing short trips this past while

Nope. Not good advice generally and certainly not in this instance.

There was no fault codes stored, only light on car was the dpf one which went out after I drove in lower gear for while. Dpf did a regen that time, and has a 16gr reading

If you read the post you'll see OP commented saying the main dealer replaced a set of injectors and no issues since.

Also aftermarket DPFs are known to give trouble they don't have the same amount of precious metals and the substrates are usually lesser quality.

My dpf light on skoda superb came on again took it for long 2 hour drive it went off then after 30 mins or so, felt a juddery feel, maybe trying to regen. Took it to mechanic month ago, he checked on pc, it did a successful regen but levels at 12gr a bit above average, I'm afraid of it going into limp mode but hopefully that long run yday helped it, that twice the light has come on🙄
