The Volkswagen Tiguan, a popular compact SUV, comes equipped with a fuel-saving technology known as the Start-Stop system. While designed to improve fuel efficiency and reduce emissions, this feature has become a point of contention for some drivers. Many Tiguan owners express a desire to disable the start-stop function, often citing various concerns. As automotive experts at keyfobprog.com, we aim to delve into these concerns and provide a comprehensive understanding of the Volkswagen Tiguan’s start-stop system.
Common Concerns Regarding Tiguan’s Start Stop System
It’s not uncommon to hear Volkswagen Tiguan drivers discussing their experiences and frustrations with the automatic start-stop system. Let’s address some of the most frequently voiced complaints and examine their validity:
1. Impact on Air Conditioning and Heating
One of the primary complaints arises in regions with extreme climates. Drivers in hot areas like Arizona worry that the start-stop system shuts off the air conditioning, compromising cabin comfort. Conversely, those in cold climates express similar concerns about heating.
The Reality: Modern start-stop systems, including the one in the Volkswagen Tiguan, are engineered to prioritize passenger comfort. While the engine may switch off at a standstill, the system monitors the cabin temperature. If the temperature deviates significantly from the set point, or if the system detects the AC or heater struggling to maintain the desired temperature, the engine will automatically restart. This ensures that the climate control system continues to function effectively, even with the start-stop feature engaged. Therefore, in most scenarios, particularly in a vehicle like the Tiguan designed for diverse climates, the start-stop system should not lead to a noticeable loss of AC or heating functionality.
2. Premature Wear and Tear on Starter and Engine Components
Another significant concern revolves around the potential for increased wear and tear on engine components, particularly the starter motor and engine itself. The argument is that frequent engine restarts, inherent in the start-stop system, might accelerate component degradation.
The Reality: This concern is largely rooted in older automotive technology perceptions. Modern start-stop systems are designed with durability in mind. Components like the starter motor are reinforced and engineered to withstand the increased cycling demands of frequent starts. Engine components are also built to handle the stresses of repeated stop-start cycles. In fact, start-stop technology has been widely adopted in Europe for over a decade, and widespread evidence of premature engine or starter failure directly attributable to start-stop systems is lacking. For typical vehicle ownership periods, especially within warranty, concerns about accelerated wear from the start-stop system are generally unfounded.
3. Fuel Saving Effectiveness and Potential Fuel Consumption Increase
Skepticism exists regarding the actual fuel savings provided by the start-stop system. Some drivers even hypothesize that the engine restart process consumes more fuel than is saved during brief engine shutdowns.
The Reality: The primary motivation for automakers to implement start-stop technology is indeed fuel efficiency and emissions reduction. Numerous studies and real-world tests have demonstrated that start-stop systems do contribute to fuel savings, especially in urban driving conditions characterized by frequent stops at traffic lights and in stop-and-go traffic. While the savings per stop may seem minimal, they accumulate over time and contribute to overall fuel economy improvements. OEMs invest heavily in such technologies because even marginal fuel efficiency gains across their entire vehicle fleet have a significant impact on meeting increasingly stringent emissions regulations and fuel economy standards.
4. Restart Vibration and Noise, NVH (Noise, Vibration, and Harshness)
Drivers sometimes find the engine restart process to be accompanied by noticeable vibration and noise, impacting the overall driving experience and perceived vehicle refinement.
The Reality: The level of vibration and noise during engine restart can vary between vehicles and even between different models of the same vehicle. While some drivers find the restart in their Volkswagen Tiguan smooth and barely perceptible, others may experience more noticeable vibration. The original author of the source article acknowledges experiencing “too much vibration on a restart”. However, automotive technology is constantly evolving. Newer Tiguan models and advancements in start-stop system design often focus on minimizing NVH. The perception of vibration is also subjective; what one driver considers intrusive, another might find negligible.
5. Acceleration Delay After Restart
A minor delay in acceleration response after the engine restarts is another point of concern, particularly in situations where quick acceleration is desired after a stop.
The Reality: There can be a slight delay between releasing the brake pedal or pressing the accelerator and the engine fully restarting and responding to throttle input. However, in most everyday driving scenarios, this delay is minimal and unlikely to be a significant impediment. As the original article author notes, “who’s gunning their Tiguan at a stop light?” For typical urban driving and daily commutes, the acceleration response with start-stop engaged is generally adequate. Furthermore, manufacturers are continuously working to refine start-stop systems to minimize any perceived lag in acceleration.
Personal Preference and Disabling Start Stop
Despite the engineering rationale and potential benefits of the start-stop system, personal preference plays a significant role in driver perception. As highlighted in the original article, some drivers, like the author, appreciate the system for reducing engine noise and vibration at idle, even prioritizing this over fuel savings. Conversely, many others actively seek to disable the system permanently.
The desire to disable start-stop often stems from a combination of the concerns discussed above, personal driving style, or simply a preference for traditional engine operation. While some Volkswagen Tiguan models may offer a button to temporarily disable the system for each drive cycle, many drivers seek more permanent solutions.
Aftermarket solutions exist to disable the start-stop system permanently or to alter its behavior. These can range from simple plug-in devices to more complex software modifications. However, it’s crucial to consider the potential implications of such modifications, including warranty considerations and potential impacts on vehicle emissions compliance.
Conclusion: Weighing the Pros and Cons of Tiguan’s Start Stop
The Volkswagen Tiguan’s start-stop system, like similar systems in other vehicles, is a technology designed to improve fuel efficiency and reduce emissions. While concerns regarding comfort, component wear, and performance exist, modern systems are engineered to mitigate these issues effectively.
Ultimately, whether to embrace or disable the start-stop system is a matter of individual preference. Understanding the system’s design, addressing common misconceptions, and weighing the potential benefits against perceived drawbacks empowers Tiguan owners to make informed decisions about their vehicle’s operation.
