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.
