Volkswagen has its own set of testing standards known as TL (Technische Lieferbedingungen) standards. Automotive testing conducted to VW’s TL standards encompasses a wide range of evaluations and assessments to ensure that vehicles and their components meet the stringent quality and performance requirements set by the company. TL standards focus on durability, safety, performance, and reliability and require extensive testing of vehicle components to ensure they can withstand the stresses and strains of everyday use. Suspension systems, engines, transmissions, and electrical components undergo rigorous testing to assess their resistance to vibration, temperature variations, humidity, and corrosion. These tests help identify potential weaknesses or vulnerabilities in the components, enabling engineers to make design improvements and ensure long-lasting performance.
