Core Viewpoint - The article discusses the reliability issues of the tire pressure monitoring system (TPMS) in the BYD Qin L DM-i, highlighting the potential safety risks associated with indirect TPMS that lacks real-time pressure display and can lead to false alarms [3][10][14]. Summary by Sections Incident Description - The author experienced a tire pressure warning during a road trip, which led to confusion and concern about the vehicle's safety due to the lack of real-time pressure readings [3][4]. - After adjusting the tire pressures, the warning persisted, leading to a dilemma about whether to trust the system or continue driving [4][7]. System Evaluation - The author conducted tests to evaluate the TPMS, discovering that the system failed to respond to significant over-inflation while erroneously alerting for normal conditions [9][10]. - The article explains the difference between direct and indirect TPMS, noting that indirect systems rely on wheel speed sensors and do not provide specific pressure readings, which can lead to misinterpretation of tire conditions [10][11]. Industry Standards and Practices - The article mentions that many vehicles priced below 90,000 yuan use indirect TPMS, while those above this price typically feature direct systems [12]. - It highlights that the choice of TPMS type is often driven by cost considerations, with direct systems being more expensive due to the need for additional hardware [13][14]. Consumer Awareness - Consumers often overlook the importance of TPMS during vehicle selection, focusing instead on more visible features [16][17]. - The article suggests that many drivers only realize the limitations of indirect TPMS after experiencing issues, emphasizing the need for better consumer education regarding vehicle safety features [17][18]. Recommendations for Consumers - The article provides practical advice for consumers with indirect TPMS, including regular manual pressure checks and understanding the system's limitations to mitigate risks [18].

Group 1 - The core viewpoint of the article highlights that Yuan Zheng Technology has been actively repurchasing its shares, indicating management's confidence in the company's future and belief that the stock is undervalued [1][2]. - As of August 15, 2025, Yuan Zheng Technology repurchased 53,000 shares at an average price of HKD 12.00 per share, totaling approximately HKD 636,000, with a cumulative repurchase of 4.858 million shares, representing 3.05% of the total share capital [1][2]. - The company's stock price closed at HKD 12.00 per share, reflecting a decline of 2.99% on the same day [1]. Group 2 - Yuan Zheng Technology, established in 1992, is a significant player in the automotive aftermarket, focusing on the research, development, production, and sales of automotive diagnostic and maintenance products [3]. - The company's product range includes automotive diagnostic tools, tire pressure monitoring systems, and vehicle lifts, with a strong emphasis on innovation and technology development [3]. - Yuan Zheng Technology has a notable presence in both domestic and international markets, exporting products to various countries and regions, thus playing a crucial role in the global automotive aftermarket supply chain [3].
