Review on 🔧 2021 Elite LAUNCH X431 PROSV 4.0 Bi-Directional Automotive Tools - Full System AutoAuth for FCA SGW OBD2 Scanner with 31 Reset, Key IMMO Program, ECU Coding Active Test, and Variant Coding - Free Update by Geoff Yates

I bought this tool to help pinpoint an engine problem I was having on my 2016 BMW 3 Series due to the warning light staying on. He tells me exactly what is wrong. After I fix the problem, the code clears successfully. I have also used this scanner to turn off the TPMS light after a tire change. In addition, full system diagnostics are also supported. The scan tool comes with a Bluetooth adapter that connects wirelessly to my vehicle. It also supports Wi-Fi so I updated everything as soon as I signed up. The design of the tablet makes it very user-friendly. Also, I'm 100% satisfied with its huge screen, I can even use it to send and receive emails on my tablet. The best thing for me is the bi-directional capability. Many functions are also available, such as B. ECU, SAS, DPF, BMS, ETS, OIL, AFS Coding. I will upload my test result when I have the opportunity to use these features. All in all, the tool does what it is supposed to. I have diagnosed several cars from Asia, Europe or USA. All can be connected to the scanner via automatic scanning or manual input. It goes without saying that time is money for both technicians and car owners, few things are more annoying than a slow scan tool and this one suits my needs perfectly. The device paid for itself dollar for dollar.
