IMHO, this should be the first thing you buy. It's only $199 https://store.ross-tech.com/shop/vchv2_ent/
The only problem is you need to know how and when to use it. I had an Automatic Climate Control fault that I thought pointed to a bad actuator. Since it was still under an extended warranty, I took it into a dealer. Turned out I only needed the basic settings reset. You know a dealer would have gladly removed my dash and replaced the actuator instead of (at the time) only charging me a $175 labor charge. Probably $205 today. R-T does not compensate me in the least for my advocating their product. I just think, most people here spend a whole lot more for things to make their cars look and run better, why not be able to help yourself know more about your car and possibly save you money in the long run. I would buy VCDS instead of worrying about how much intake noise your car makes.
