What is the battery model for the Volkswagen Tiguan L's start-stop system?
3 Answers
The battery model for the Volkswagen Tiguan L's start-stop system is L2-400. Below is an introduction to the Volkswagen Tiguan: 1. Overview: The Volkswagen Tiguan is a car produced by Shanghai Volkswagen, with its price announced on March 26, 2010. This compact SUV made its first appearance to consumers at the 2009 Guangzhou Auto Show. 2. Development: Upon its debut, it received widespread attention and popularity. The introduction of the Tiguan broke the awkward situation of German cars lacking domestically produced SUV products, while also providing consumers with more and better choices. 3. Structure: The Shanghai Volkswagen Tiguan offers four versions with a total of seven models: Urban, Trendline, Comfortline, and Highline. They are equipped with Volkswagen's flagship 1.8TSI and 2.0TSI engines, which deliver excellent performance in both power and fuel efficiency. The matched 6-speed manual transmission and Aisin 6-speed automatic transmission can better utilize the power, offering a thrilling driving experience while also being more environmentally friendly in terms of emissions.
For the Volkswagen Tiguan L's start-stop battery, AGM batteries are generally recommended, with common models such as the Varta AGM 019 or OEM-specified options like the 5KO915105 AGM battery. This is because the start-stop system requires high discharge and rapid charging capabilities, which conventional lead-acid batteries simply cannot handle, often leading to system failure. AGM batteries feature a unique internal structure that can withstand the vibrations and loads caused by frequent start-stop cycles, preventing sudden engine shutdowns while driving. I've driven my friend's Tiguan L a few times, and the original battery typically has a 70Ah capacity and 760 CCA rating, with the model number clearly stated in the manual at the dealership. When replacing the battery, ensure the voltage matches 12V and check if the battery compartment size is suitable. Using a non-AGM battery can damage the alternator or starter components, increasing future repair costs. It's recommended to inspect the battery every 3 years or 60,000 kilometers, keeping the terminals clean and dry to extend its lifespan. The start-stop system significantly saves fuel in city traffic congestion, but it drains the battery faster, so avoid cheap, low-quality alternatives—stick with reputable brands for reliability.
Speaking of the start-stop battery for the Tiguan L, I've encountered this issue before. At the time, the 4S dealership replaced it with a Varta AGM 019 model, which they said was the standard configuration. EFB batteries are sometimes used but not as durable as AGM ones. The start-stop system places high demands on the battery, requiring it to withstand frequent high-current surges to restart the engine. After five years of driving, my car's battery aged and triggered a warning alarm. The replacement process was straightforward and cost around 800 yuan. If you buy it online yourself, the model must match the original specifications, otherwise the vehicle's ECU will report fault codes, compromising driving safety. I've seen many car owners share their experiences on forums, recommending regular voltage checks with a multimeter—normal readings should be around 12.6V. If the start-stop function frequently malfunctions, prioritize checking the battery over other components. Remember, the battery is located at the rear of the engine bay; disconnect the power before removal to avoid short circuits. These AGM batteries perform well in low temperatures, making them suitable for northern winters, but also pay attention to heat dissipation during hot summers. In short, don’t overlook routine maintenance—it can save you a lot of money.
