Mercedes C250 2012 DPF regeneration
ฝัง
- เผยแพร่เมื่อ 7 ก.ย. 2024
- Symptoms:
- Check engine light is on.
Fix:
- Ensure no engine related fault codes are present (they will prevent the DPF from starting)
- Ensure there is more than 25% fuel in the tank
- Start the DPF regeneration with the scan tool
- After DPF regeneration is complete, reset the ECU and check that no DPF related fault are present.
- Take the car on a short test drive to verify the check engine light stays off and no fault codes come back.
Tool used:
- iScan3

Turn off eco mode when doing regeneration
cool ... thank you for help
Dear friend u did a great job 👍
Which can also be solved by telling them to run the car longer, maybe ask them to take a quick blast up one junction or two of a motorway. most of these new cars become blocked due to short trips.
Thats not the only way you get these issues. Sometimes you get a issue with Turbo or split boost pipe and so on and the Turbo will burn for fuel and oil and very quickly block the DPF up and once it hits a certain level it won't allow itself to automatically regen.
Why are you going over 100 km/h when the procedure clearly states to keep speed under 50 km/h ????
Probably that warning has to do something with safety reasons - if you get distracted...
But here the dude doing the diagnostic is not driving so... It doesn't really matter. For the engine is pretty much the same story if you drive with 2000 RPM at 100 km/h or 50 km/h. What really matters is the RPM. You need to build some RPM in order to heat the DPF.
This is just my suggestion tho, I'm not a pro, but occasionally I drive with higher RPM (around 2500-3000) in order to clean the DPF. If it is not terribly blocked, the car will do a regeneration without even noticing it, in order to do that - you need to drive on a highway on a lower gear with enough RPMs and the magic will happen, even without the fancy tool.
I tried the long trip keeping the revolutions up with my C220 cdi but light still on. Mine was over 360 as well.
Great job! Φίλε μου είσαι έλληνας?
Great video. I have the issue with my 2008 E320 but in Texas -USA my local MB dealer does not do this kind of DPF regeneration. They want to install a new DPF instead clean my old one. I had my actual DPF cleaned by a company in Texas that only clean DPFs but I still have the engine light on and the code for DPF. The unit was tested after clean up and the test show as soot free.
I had the code cleared by some mechanic scanner but the code came back.
My car drive good, good fuel mileage but the engine light on bothers me.
Why do we need these dam things anyway ..more things on already expensive cars to go wrong with , To get loaded with payment repairs ..
Agree !!
Where about u from
And what causes that DPF is over 300% ????? Thats your problem to look for !!!
What scanner did you use? Which city are you in? Can you please do the same thing for my ML 350 diesel?
Ashoke Roy get on highway set it on 4th gear drive it on 2000rpm for 15 to 20 min
Good video. No need fancy tool like that. I use vident i400au and does the same job www.fueleconomysolutions.com.au/vident-i400au-professional-scan-tool-all-system-fu
@@BlackJackSpielerherz Sell it as soon as possible
Je conseille fortement une vidange moteur après toutes ces régénérations. Car du gasoil est descendu dans le bloc moteur. Quand il y a régénération du gasoil est envoyé dans la chambre de combustion à un certain moment pour ne pas être brûlé. ( certains moteur ont un injecteur sur la ligne d’échappement et donc non pas ce problème mais très rare car trop coûteux car un injecteur de plus )Et donc finir dans le fap pour pouvoir faire augmenter la température vers 550 700° . Il y a donc toujours du gasoil qui descend sur les parois du cylindre qui va dans le carter moteur .Faire le niveau d’huile avant et après pour ce rendre compte . Du gasoil dans l’huile n’est vraiment pas bon surtout pour le turbo. 😊
Is this for motorway noticed on regen 2 time says
What scan u using
