Mercedes B Klasse diesel engine light and power loss

My Mercedes B Klasse 2023 diesel has only 22609 km but the engine light is on. I noticed reduced engine power and smoke when accelerating. Could it be the diesel filter?

Sounds like a DPF issue. I had similar symptoms with my B Klasse, regeneration didn't solve it. Any chance it could be a sensor fault?

How did you check if it was a sensor fault? I thought a vehicle inspection would be the only way to be sure about the diesel filter.

I didn't check it myself, the workshop did. They said the engine light and smoke pointed to the diesel filter being defective, which caused the reduced power. Definitely get it checked.

Thanks. It was indeed the diesel particulate filter, cost me 1550€. At least it's fixed now.
