2025 LAUNCH X431 V PRO 4.0 Elite Bidirectional Scan Tool (Same As X431 PRO3S+),Online Coding &38+ Reset,Full System,VAG Guide,2 Yrs FREE Update

this is a truly amazing tool. i wish i was a better mechanic to fully use all its functions.ive been using this for a bit. my own car, coworkers, and family to see if there was anything suspicious going on under the hood. its automatic diagnostic runs smoothly and creates a checklist of systems and features.you can see from the pictures what the case looks like. the pictures from amazon are adequate but i put mine here to prove i have the diagnostic tool and im not some company smuck writing a vague review.the tablet is good. it is a standard tablet so i can use it for casual games while im looking busy. it has a camera i use to take pictures to show people what im working on. it connects to networks for internet. i get youtube. it is a tablet and does what a tablet do.it comes with more adapters than i know what to do it and for cars im far too poor to ever get my hands on. the brick that plugs into the OBD II will not fit into my FORD without the extender adapter. the plastic housing is preventing access. i could have unscrewed the tip from car and plugged it into the dangling card but the kit comes with everything.i can go on forever.. the live data is immensely helpful too. i haven't needed it to repair anything yet but it was cool to see the data scroll for a healthy if not aging FORD.TL;DR - its only limitation is user.the price is steep but if i were to charge myself and the people i have been testing this tool i could recuperate the cost. there are free updates for 2 years. it is not mandatory to update after the two years and you can still use the tool after the two years. which is one more reason i got this. look at it this way, the price is a 2 year subscription. for , like 65 bucks and tax you get a tablet, OBDII, carrying case and every single adapter. its a great price.lastly, you have access to a database, technical support, car support, and an invite to facebook which gives yo more access to information.

This tool has done everything I needed to do with my Porsche Cayenne S 958. From deep diagnostic reports to clearing faults in various modules to coding special hidden options and a steering wheel change. I've used it to help friends diagnose engine lights and code modules. It gets pretty deep with BMW as well and has some special functions with Mercedes. Although there is not a ton of support from Launch, there is a lot of info out on the internet for specific vehicles, then you just have to dig into the menus of the software while connected to your vehicle and figure out how to apply settings from other sources using this tool / software.I wish Launch would sell software only, as it's basically just a good spec Android tablet with their app loaded and licensed. I don't really need another tablet, and haven't had any use for any of the myriad of cables, just the OBD2 dongle for vehicles made in the last 15 years or so. It's a Bluetooth dongle that stores neatly in the rugged protective case over the tablet. If they just sold the Bluetooth dongle and the app license any recent Android phone could do the same job.Overall this tool is a great value for anyone who wants to be a DIY mechanic on aging complex cars that would cost a bundle to fix at a dealer or specialty shop. It has certainly paid for itself in diagnostic info and time savings. I was at tire kingdom just recently and they charged an old lady $142 just to hook up the computer diagnostic on her old Ford Focus to check an engine light. Wish I had it with me at the time. I would have done a 10 minute report for free complete with emailed report.

I'm a DIY guy with 4 cars. I bought the Launch X431 V PRO in hopes to get more information regarding a DTC errors on my 2000 Mercedes ML430. In using the X431 I have found this to be an extremely powerful diagnostic tool and easy to use. The first thing I was able to do is see all the faults in all the sensors I had repaired through the years which were still logged into the vehicle although I had believed I had cleared the codes years before. I believed these codes were cleared due to clearing the check engine light with a single direction OBD II reader. Although this did made the light reset the error codes were still logged. This is very important as I drive the vehicle each day as my work car and would like to be informed of possible faults prior to a check engine light error. In short this tool will allow you to run and monitor different parts and accessories on your vehicle while monitoring other sensors to get a good idea of how multiple system interface with one another. I was having a problem with the secondary air pump on this vehicle. By using the Launch X431 I was able to manually start the secondary air pump while monitoring the O2 sensors. WOW, what a big deal. This job while using a vacuum pump, vacuum gauge and a OBD II reader would have taken quite some time to set up and run, but with the X 431 it took seconds. I look forward to leaning more about the uses of this tool. Highly recommend!!
