How to permanently disable the start-stop function on Audi Q5L?
2 Answers
Audi Q5L can only permanently disable the start-stop function through computer programming at a 4S dealership; it cannot be done by the owner. Below is an introduction to Audi's start-stop system: The Audi automatic start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move again. This technology can save up to 5% of fuel under normal driving conditions and up to 15% in congested traffic. Here's how to temporarily disable the start-stop function on Audi Q5L: After starting the vehicle, locate the start-stop switch near the center console and turn it off. The dashboard will then display a message indicating that the start-stop function is unavailable. However, if the ignition is turned off and on again, this step must be repeated to ensure the system remains off.
I've been driving an Audi Q5L for several years and always found the auto start-stop feature quite annoying. Every time I stop, the engine shuts off, and when starting again, there's a noticeable vibration, especially in traffic jams, which feels very uncomfortable. To permanently disable it, I tried several methods myself. I found that the factory settings only allow temporary deactivation, such as pressing the start-stop button on the center console, but it reactivates the next time the car starts. Later, I used an OBD tool like Carista, plugged it into the port under the steering wheel, connected to a mobile app, and was able to modify the ECU settings to permanently disable the start-stop. The whole process isn't too difficult, but requires careful operation to avoid accidentally changing other settings that could affect vehicle performance. I personally recommend reading the manual thoroughly before attempting or consulting a professional technician, as this involves the car's computer system, and mistakes can cause issues if you're not familiar with it. Additionally, after permanent deactivation, fuel consumption might slightly increase, but for daily driving, reducing irritation is worth it.
