Does the cc2021 model come with a particulate filter?

The cc2021 model is equipped with a particulate filter. A particulate filter is a ceramic filter installed in the diesel engine's emission system, which captures particulate emissions before they enter the atmosphere. Function of the particulate filter: The particulate filter can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Principle of the particulate filter: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine's exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon smoke particles are adsorbed onto the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon smoke particles into harmless carbon dioxide that is then emitted.
I've been running an auto repair shop for over a decade and just replaced the particulate filter on a 2021 CC. This generation comes standard with GPF across all trims, located in that bulge section of the mid-pipe. Since China 6B emissions, VW mandates these on all turbo models - I've disassembled 20+ units and never seen one without it. Tuners keep asking if they can remove it, but I'd advise against - deletion causes smelly exhaust and triggers CEL.
Last week in the car owners' group chat, six owners of the 2021 CC model confirmed that the vehicle comes with a factory-installed particulate filter. This device automatically regenerates at low RPMs. If stuck in traffic for too long, a warning will pop up on the dashboard, and a short highway run will resolve it. Many feel it affects performance, but actual tests show the 0-100 km/h acceleration remains at 7.5 seconds with no noticeable decline.
