Launch X431 V+ Reviews – register, pair Bluetooth, compare with Snap On / Autel 908

Launch X431 V+ PRO3 WILL NOT WORK until you do 2 things.

the first thing is Registration

Basically need to use the serial number from the back of the device. Then you take that serial number and email it to the seller. After they activate your serial number.


The second thing is “pair” the wireless OBD2 connector:

you have to “pair” the wireless OBD2 connector to this. Somewhere on one of the diagnostic screens, up in the corner or something, it will ask you for the number that is on the wireless OBD2 connector. You have to put that in and essentially pair them, before this can work. That way if you ever lose the wireless connector, you can just buy another one for cheap and pair that one. Once they’re paired, you don’t have to do it again. But you won’t be using it until you do it.


After complete the two things, you could download all the updates directly on the device



The interface is like your standard Android tablet and it updates just like you would update your laptop computer. When I contacted the seller, who was very helpful, he did mention that the update timeframe is one year. But he assured me that the product can be used for many years afterwards with no worries. So as long as you are not constantly working on the latest models or cars, this should not be an issue.


Test report on what can work:

  1. I have used X431 PRO3 on many cars in my shop under repairing ,Incompatible with none of them. Bunches of special functions really helped me a lot. Far way beyond my expectations. This absolutely is the best no matter consider the price and functions.

  1. read code and clear fault memory and etc. The function of reading DTC can display the detailed information of DTC records retrieved from the vehicle’s control system, which is really helpful. This device also has many powerful special functions which can nearly diagnose every module of full systems of cars.


  1. The diagnostic connector of this device only for 12V car diagnosis.


  1. X431 PRO3 scanner worked flawlessly in Mexico and was put up to the test with vehicles from Latin America and US, it connected with various makes and models, so far ever thing we throw at it, communicates with.It has also communicated with the Nissans 4 cylinder diesel engines and many other small diesel engines sold in Latin America.
    One more comment, the scanner has a 10 inch display and connects via Bluetooth which makes connectivity much more easier and clean, no more cables hanging or keys to insert, the battery life is great and you even get all the other amenities that android offers. it has a front and rear facing camera and the case is made up of a combination of plastic and rubber to protect it from drops. Inside the box comes all the connections and adapters needed for OBD2 and OBD1.

    One more, this buy came with free two year updates which leaves us with a total of three year vehicle coverage which is hard to find.

    I would definitely recommend this X431 PRO3 scanner to all of you who want an OE level device and even for the professionals.


Compare with $8,000 Snap On units:

In my opinion, its well worth the money. It does the same thing all those overpriced $8,000 Snap On units do, for 1/6th of the price. Snap on can’t write the info reading software for the cars, they must rely on the manufacturer to tell them everything. So in that way, they’re no different. And look it up, that’s the only real way that matters. Anything else is just fluff and puff you don’t need. Buy X431 V+ PRO3, instead of getting ripped off. Now there is something that I think the company should be more clear about. This WILL NOT WORK until you do 2 things. You must email them your serial number. It’s useless until you do that. Apparently they’ve had a lot of knock offs, so they’re protecting their IP by having you email them before you can actually download the necessary software for it. That confused me initially, as it wasn’t mentioned in the paperwork. At least nowhere that I could see.

Actually, it’s not a fair comparison due to the Snap On being much more expensive and also has built in lab scope, etc


Compare with Autel MaxiSYS Pro MS908P:

X431 V+ PRO3 scanner is a great ADDITION to have if you already have some better ones. The newest version of the software only allows you to view 4 DATA PIDS at a time!!!!

I also own an Autel MaxiSYS Pro MS908P and it is at least twice as good as the Launch, for about €2300


In conclusion:

X431 V+ PRO3 scanner will do most of what you need but if you are a professional tech, this should only be considered as a back up or to try when your primary scanner fails to have certain feature.


How long X431 V+ PRO3 can be used:

I checked a few user groups on facebook and this seems to be the general consensus, that the useful life of one of these expensive auto scanning diagnostic tools is about 5 years (assuming you haven’t beat it to death before then), and that Launch makes the best third party tool out there.


Thanks to the real X431 V+ PRO3 scanner users of
