2017 W205 DPF issues

[MarcusBHP]

dpf issues, cleared the dpf out but stil shows 400% full. Will xentry fix this, I tried with a thinkdiag and it won’t do anything dpf wise except reset dpf pressure sensor.

You can try reset DPF adaptation by Xentry for first aid. Usually there is a reason why it has flagged as full, further investigation could be usefull.

Thanks for the reply Peter, as soon as i am able to get Xentry loaded up on the laptop i am definitely going to see what Xentry can fix, i have a openport clone ready for this

Once your Xentry is setup try and force regen & check if values go down ash content soot content etc.

Check Pressure Sensor for airflow. Also check all the hoses/hardlines from and to the sensor. if one line is open end or blocked, the readout of the sensor will always tell you the DPF is full. Good Luck.

It worked for me, the problem was the nox sensor

Can anyone explain wait is the real benefit of those addons for diesel motors - DPF, AdBlue, NOX etc. So not to explain what it does, what is benefit except many cars owners often have problems with them and the costs are very high... I think their only purpose is to take some money from car owners

To pass needed emission regulations, they are just needed if you like to manufacture or sell cars. Until EU4/EU5 everything was easy, most of time just EGR and DPF. EU6 emission level means EGR and DPF is not enough, also SCR needed. SCR is the system for "AdBlue" and NOx is emission it reduce. All this comes from emission regulation. If we like to reduce emissions overall, also cars must be under it. It is just fact we like it or not

Systems has problems like all automotive technics. People do not like to see point to repair systems because they have problem with attitude. Why I should spend money for something that I don't get anything back? If I spend $700 for LCD-TV I can watch Netflix all nights long. If I spend same for NOx sensor I get only repaired emission system for car (can not see difference). They said "do not own anything you are not able to fix or get fixed".

The purpose of installing a particulate filter and urea injection behind the particulate filter is to reduce the harmful impact on the environment and reduce the temporary impact on health. The particulate filter retains solid soot particles from the combustion of diesel fuel, and urea allows nitrogen oxides to be decomposed into water and carbon dioxide that are safe for human health.The bastards that are not cleaned after the particulate filter can cause cancer in humans. The NOx sensor is designed to evaluate the efficiency of urea injection in a selective catalyst.

The picture is just an example of faulty NOx sensor which needs to replace with new one and the costs is about 500€. My point it that all these add-ons to reduce the emission are very expensive and besides that it is common well for environment, but it is way to take some additional money from cars owners. Does trucks have also these systems, do they have issues?
