Launch CRP909 is the most cost-effective all-in-one diagnostic tool, facts speak louder than words, here is a good example:
Launch CRP909 works well for my 2015 BMW, it automatically scans the VIN and learns the model of your car, you don’t even need to choose any car model, it scans all systems fault codes and determine what is required to fix cars. Let me know I can save money and time when some of component broke before, and I usually send it to garage and they always tell me I need to replace a new one, but now I know, actually some codes can be erased directly and don’t need to replace anything, I have to admit the tool is really powerful, highly recommend!
