Movano DPF Regeneration Failure

I had similar issues with my Movano. The exhaust back pressure sensor monitors the exhaust gas pressure, needed to correctly operate the engine and especially important for DPF regeneration. When it fails, regeneration is not possible anymore. Have you checked the sensor itself for any obvious damage or loose connections?

Thanks for the quick reply! I gave the sensor a once-over, but didn't see anything obvious, like melted wires. Is there a specific way to test it, maybe with a multimeter? Or am I better off just replacing it?

Testing it with a multimeter is possible, but you'd need the correct values for comparison, which can be hard to find. Considering the symptoms and the error code, the sensor is the most probable cause. I would suggest visiting a trusted workshop and have them check it out.

Appreciate the advice! Took it to the shop, and you were spot-on. The exhaust back pressure sensor was indeed defective. Replacement cost me around 245€, but at least the van's running smoothly again. No more smoke, and the DPF is regenerating as it should. Thanks again for the help!
