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.

Checked the environmental compliance list, which clearly states in black and white that the 2021 CC meets the China 6B RDE standard and must be equipped with a particulate filter. Some owners have seen chassis photos at the 4S store, where an additional metal canister is clearly visible in the middle section of the exhaust pipe. Under the new regulations, turbocharged cars can hardly avoid this, unless you opt for older China 5 stock vehicles.

After carefully comparing the specification sheets, I noticed that the 330TSI and 380TSI have different part numbers for their exhaust systems, but both are equipped with GPF modules. The main difference lies in the particulate filter density - the higher-power version uses a ceramic substrate with finer honeycomb cells. Remember to avoid fueling at small gas stations, as impurities can easily cause clogging. A single repair for this could cost over 3,000 yuan.

Tested my friend's top-trim model, even the OBD computer can display real-time particulate filter data. During idle, when exhaust temperature rises above 220°C, it automatically cleans – this active regeneration technology doesn't significantly increase fuel consumption. Northern owners should note: regeneration efficiency is low during cold starts in winter, recommend doing a monthly high-RPM run.
