Here are the decontenting items for the 2021 domestically produced BMW 3 Series: 1. Removal of the built-in car hard drive: The 2021 model's infotainment system model HU-H3_F has eliminated the built-in car hard drive, no longer supporting music collection storage. To play MP3s, you must directly insert a USB drive into the infotainment system's USB port. Due to this decontenting, the 2021 model comes with a 3-year complimentary QQ Music membership, allowing direct playback of internet music via QQ Music in the car. 2. Engine decontenting: The 2021 320 and 325 models are equipped with the low-power B48B20C engine, which cannot be flashed to high power. Additionally, apart from different ECU control programs, the high and low-power engines also differ in hardware. The high-power engine uses an independent dual-reservoir water cooling system, while the low-power engine uses an integrated single-reservoir water cooling system. 3. Removal of the headlight base guard plate in the engine compartment: The 2021 model has eliminated the headlight base guard plate. 4. Cancellation of the factory optional electric lumbar support: Starting from February 2021, the 2021 models rolling off the production line have removed the electric lumbar support included in the package, retaining only the electric tailgate.

Last year I upgraded to a 2021 BMW 3 Series, but noticed several cost-cutting measures in the details. The engine bay no longer has sound insulation padding, making acceleration noise quite noticeable – even city driving feels noisy now. The power trunk closing function was removed, requiring manual force to shut the trunk every time, which is inconvenient. The key fob design was simplified too, losing the premium feel of previous models. Seat material changed from genuine leather to synthetic leather, becoming stuffy and non-breathable during summer. Interior materials like dashboard trim feel cheaper with more hard plastics, lacking the refinement of imported versions. These downgrades affect daily comfort. While manufacturers likely did this for cost control, the unchanged price point feels unfair. I recommend thorough test drives to inspect these details before purchase.

How to Handle the Procedures for Vehicle Wrap Color Change?

To apply for a change in the body color of a motor vehicle, the following documents must be submitted according to the "Road Traffic Safety Law": "Motor Vehicle Change Registration Application Form," identity proofs of the motor vehicle owner and agent, the motor vehicle registration certificate, and the motor vehicle driving license. According to Article 6, Chapter 2 of the "Road Traffic Safety Law," if the color change area of a motor vehicle does not exceed 30%, no change registration is required. Conversely, if it exceeds 30%, it must be filed and registered within 10 days after the vehicle color change. Precautions for vehicle color change: Before changing the color of a motor vehicle, it is necessary to consult the vehicle management office where the vehicle is registered to confirm whether the region allows changing the vehicle color using wraps. If the region does not support this method, the change cannot be filed, and the wrap must be completely removed to restore the vehicle's original color. Additionally, according to the "Motor Vehicle Registration Regulations," owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply for change registration with the vehicle management office. According to Article 10, registered motor vehicles must apply for change registration with the local vehicle management office under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Replacement of the entire vehicle due to quality issues. Change of use nature, such as commercial vehicles converted to non-commercial use or vice versa. The motor vehicle owner's residence moves out of or into the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with specified patterns and equipped with alarms and signal lights as required. Other motor vehicles are prohibited from painting, installing, or using the exclusive or similar patterns, alarms, or signal lights of the aforementioned vehicles. According to Article 56 of the "Motor Vehicle Registration Regulations," if the body color is changed without completing the required change registration, the traffic management department of the public security authority may issue a warning or impose a fine. The vehicle may also be impounded and required to revert to the original body color.
