Inspecting the exhaust aftertreatment system

This 2018 BMW F36 had issues involving its AdBlue/SCR and DPF systems. The DPF had already been washed, but the problem remained. The inspection included system components such as the NOx sensors and the catalytic assembly.

DPF condition

Several cracks were visible in the filter’s ceramic core. With this type of damage, washing cannot restore the filter’s structural integrity. The video also shows signs of previous work around the mounts, but it does not establish the exact cause of every system fault.

The customer’s decision

After the inspection, the customer decided to proceed with system removal and software changes. The video shows this decision and the diagnostic process, but does not confirm that the BMW work was completed or that a post-work test was carried out.
