Launch X431 Pro Mini reviews -wins many tools

I’m a Launch user living Atlanta, US, and very pleased with this Launch X431 Pro Mini Bluetooth. Here I plan to write an objective review on X431 Pro Mini. I really highly recommend it for following reasons.
Package came in a poco time and a good condition. This unit more likes a tablet but vehicle diagnostic tool when looking at the shape.


X431 Pro Mini unit is small, the smallest of the scan tools that I’ve dealt with. This tool is the newest Launch product out on the market for 2017.

The first thing I have to do before using the product is to register an account via the X431 pro mini APP on the main screen. I was asked to enter my number, user name and password. After all these done, I have an account available to log in the APP to upgrade the software.

I took a big risk in buying X431 Pro Mini because it wasn’t released in North America. But good thing it worked out because the updates for the software are newer than the ones in North America. Example: on the X431 pro Mini Porsche firmware V21.91. In current software from North America it’s V21.81.

It’s all about the software, doesn’t matter where these machines are made, the software has to be current.

Previously I had the older Launch GDS which gave me issues with Acura, Honda, Toyota and Nissan. Thank god the issues have been fixed with this new X431 pro Mini unit. By far, the BMW, Benz and VW software is the best you can find on the market.
I applied it to my Porsche, and it accurately solved the oil indicator and cleared the DTC. I also used it to troubleshoot problems of my wife’s AUDI, couple of problems was found and fixed without issues.

My Audi 8 series Brake pad was changed a while ago by myself, and the indicator light was really annoying, I googled for solutions, it said my car need to do the brake reset. So just bought this device on and perfectly solved my problem. I also applied it to my other cars and did the CBS reset, Steering Angle Calibration and TPMS Reset.
I used and bought previous Snapon- Verus, Autel and PIWIS, Vagcom. This X431 pro Mini tool by far is one of best well-rounded ones. As a private car owner, it’s necessary to own this sort of helper, but for technicians, I bet it is a must have. With this functional and practical device, I can at least save 2000 dollars per year, also labor and time. Worth for the money.

Launch X431 V 8 inch Test Great on Skoda Rapid 2017

This morning, i have received the 2017 version of Launch X431 V 8 inch tablet, for my repair

work in the garage.

Each item was packed well in a box, incl the  X-431 V 8inch tablet and all full cables (OBDI and

OBDII), a password envelope, a scanner protection sleeve, a x431 v user manual, some connectors, looks good.


In the afternoon, i tested on the first car; it’s Skoda Rapid the 2016 year.

For the first time to use it, i went to Launch x431 v 8″ tablet application via the tablet and

registered it first, with the user name and pass


Then downloaded VW software to test Rapid 2016





Went to European, then VW

This Launch x431 V scanner supports VW full system, incl. Power, chassis, body, info, seat &

door, A/C,etc.



Next, plug the connector to the DLC socket on the car


Ps. The connection diagram from the manual


Then had a quick test for the car


Test result: all ok.


Also, i tried the special function… did a steering angle learning


steps as the tablet displays:

1 start the vehicle

2 drive in a short distance straight line on a level surface at a speed not higher than 20km/h

3 while driving turn the steering wheel one turn to the right and one turn to the left

4 when having the steering wheel straight again stop the vehicle with the wheel’s pointed


5 ensure that the steering wheel is not moved again

6 keep the engine running and do not switch off the ignition

7 system voltage at least 12.0v

My thoughts:

Automotive Diagnostic Tools x431 v has 23 languages available (it’s said to add more) and it’s very easy to change the setup language by users (no need any help from the factory; ds708 needs that). And the new Launch x431 v covers almost full European and USA cars. Of course, no problem with Asian cars. And works good Brazilian, Indian, Malaysian cars also.
