Mercedes Citan problems with the regeneration of the diesel particulate filter
(Translated from German)
Summary of the thread
The 2017 Mercedes Citan is experiencing issues such as black smoke from the exhaust, a lit check engine light, power loss, failed DPF regeneration, and a strong exhaust smell. The suspected cause is a heavily loaded diesel particulate filter (DPF). One solution is to clean or replace the DPF and possibly some sensors, as suggested by a fellow Mercedes owner who experienced similar issues. After having the DPF cleaned, the vehicle's performance improved significantly, with no more black smoke, full power restored, and the exhaust smell eliminated.

Hi, thanks for your reply! Do you remember how much you paid for cleaning and replacing the sensors? And has anything come up again since then? Kind regards

Hello, yes, I can help you with that! After I went to the mechanic, the diesel particulate filter (DPF) was completely replaced as it was irreparably damaged due to the high mileage. The costs for this amounted to around €1550. Since the repair, my Vito has been running perfectly again and I have had no further problems with the DPF or other sensors. I hope this helps you! Kind regards

Hello, thank you for your detailed information! That sounds pretty expensive, but it's good to know that everything ran smoothly again after the replacement. I recently went to a mechanic near me who is really great. I told him about the problems and he also said that the DPF either needed to be cleaned or replaced. I brought the car in the next day. The mechanic made a detailed diagnosis and then recommended that I have the DPF cleaned first because it would be cheaper than replacing it completely. Cost: around €400. After cleaning, the Citan ran like clockwork again. No black smoke, full power and no more nasty smell from the exhaust! The engine indicator light also finally went out. Really a total relief! If anyone in the area is looking for a trustworthy mechanic: Werkstatt Müller is really recommendable. Best regards

Hello, I had similar problems with my 2014 Mercedes Vito Diesel. I also had black smoke, loss of power and the DPF regeneration failed. My mechanic confirmed that the diesel particulate filter (DPF) was heavily clogged due to the high mileage. This is definitely a more serious issue that you shouldn't ignore. In my case, the DPF had to be cleaned and some sensors replaced. After that, the car ran perfectly again. It's best to find a workshop that has experience with cleaning or replacing DPFs. Good luck! Best regards
Exactly which sensors were replaced?

Exactly which sensors were replaced?
The Diesel Particulate Filter (DPF) is typically located within the exhaust system, under the car, and close to the engine. However, the exact location can vary depending on the model of the car. It's best to refer to your vehicle's manual or consult with a professional mechanic for the precise location. Do you have any other questions?

I'm sorry for the misunderstanding, but as a mechanic expert, I don't have information about specific workshops or their locations. I would recommend asking SeliSchm directly or searching online for "Werkstatt Müller" to find their location. Do you have any other car-related questions I can assist with?
