As with previous Launch Diagun models, the new X431 Diagun can be used with a cable connected to the car or via a Bluetooth wireless connection. This allows the user to be inside or outside of the car during diagnostic testing.

The battery is also bigger and longer lasting in the Diagun III and connections to vehicles are faster and more reliable than most other professional diagnostic tools. Comparisons and analysis for diagnostics have been made easier and now two datastream waveforms can also be displayed on the screen at the same time.

  • *****Very Good

    By Dr. David Bennett

    A fantastic bit of kit, invaluable for use in keeping Emergency vehicles on the road. Purchased this Diagun after light came on a Volvo. Main dealer wanted £50 plus vat for 1 test. Purchased own Diagun, located fault code in seconds and the fault in full. Light Reset after locating fault. This equipment is invaluable for ALL, and literally will save the public many hundreds of pounds, and small garages thousands in a matter of a few years. Highly recommended equipment, and fantastic service from Diagnostics 4U. We also assist our Armed Services personnel in use of this equipment aiding them finding employment in it's use. Thanks to Diagnostics4U for you and ALL THEIR SUPPORT and HELP.

  • *****Excellent tool

    By Steve scaling

    Suprised how comprehensive this kit is so far the software seems to talk to everything including Nissans NATS system easily pulling the id code off the system then passing it thru the supplied code generator the resulting unlock code instantly unlocked the security and then re-registered the keys great value for money

  • *****x431 diagun 111


    hi all well have had this diagun 111 aweek now,wow what a machine and great value for money .was useing a solus for the last 3yrs whitch needed up dateing at 500 plus vat an up date y on earth would u wanna spend that kind of money each time when this do's more.been in the trade over 30 yrs and we all no they dont really earn there money,need more of a service now days so dont be fooled,oh and only buy from a rep company like diagnostics 4 u,great service and delivery and peace of mind.

  • *****New Launch Diagun III

    By General Autos

    Diagnostics4u was recommended to us by another garage who bought one of these. Our old diagnostic tools all need software upgrades but the cost to upgrade them is actually more than the cost of buying one of these brand new. So far this Diagun has been absolutely brilliant and connected to everything wev'e tried. I just wished we had bought one of these sooner!

  • *****BARGAIN

    By Express Auto Servs

    Very low prices for the GENUINE Launch machines:) Surprise, surprise, they are the real deal. Bargain of the year!

    Like many others, we have bought tools direct from China in the past, been there, done that and suffered all the usual problems with really crap service, no after sales, no warranties and no software updates.

    We have been using Launch tools for years now and they have always been better than most other professional tools.The choice of diagnostic functions including adaptations, coding and programming for a lot of cars is especially good considering the low price of these machines.

    We bought 2 of these new Diagun 3 models from diagnostics4u for our workshop and mobile unit and saved quite a bit of money so obviously very happy here. Good to come across a genuine UK company that's NOT ripping us all off THANK YOU

  • *****THANKS



  • *****Best buy

    By Richard Knowles

    These guys are very helpful on phone and i got exactly what i ordered, very impressed with machine best thing being able to leave machine plugged in to do diagnostic scan while car up in the air on ramp getting on with other repairs.

  • *****Diagun

    By Lee best

    a very good product ive used a snap on solus plus and this diagun is alot better well worth to get one

  • *****Amazing!

    By Dmitriy Kalani

    This is the best tool i tried yet and the price is very good does everything and is easy to use which is what i wanted perfect for my business. delivery was fast to russia took 3 days thank you

  • *****Diagun x431

    By Craig

    Absolutely brilliant piece of diagnostic equipment covers exactly what you meet day to day in a busy workshop. Additionally the service from the people who run Diagnostics4u are as good or even better than the machine. They know about what they sell and are more interested in what you need rather than what they can sell you, even if its cheaper. Rare to find a company like that!!!! im glad i found them.... Thanks again team you deserve this review, cheers, CW

  • *****Awesome

    By Dr. Paul Dembo

    This product and customer service is worth more than 5 STARS

  • *****Make Sure You Get Warranty & Updates

    By Michael Ellis

    You can get these a bit cheaper from China. Getting the software updates and warranty repairs is a gamble though and definitely depends on who you deal with.

    Someone I know bought his Diagun from China 2 months ago and so far he has had no problem but other people I have spoken to swear they would never buy from someone in China again because they got no help with anything after they paid their money and they had to pay more money to get software updates they should have got free

    Wherever you buy your Diagun you will find these are excellent profesional compact machines which do a lot and you can't get much better, even if you spend a lot more money, but you will definitely need the software updates as they come out if you want to cover as many different car systems and models as possible. And, make sure you get a repair warranty because these are small computers and like anything else they can break down

  • *****Really, Really Good

    By Charlie

    I read all the reviews here and did some careful research and after 3 weeks I finally took the plunge and bought one. That was 5 months ago and so far I am really pleased. I agree with everything said in the other reviews here. These really are the genuine Launch tools and as other people have said, the Diagun is a fantastic professional diagnostic tool. I'm still learning new things to do with it every week because it's much more powerful than I ever thought. The functions available for so many cars constantly surprises me. I can only say, get one of these and throw all your code readers and diagnostic cables away or sell them because they are kid's stuff compared with this tool.

  • *****Customer Service Is Key

    By Muhamed Ahmed

    You may find a better price elsewhere, from China etc. But when something goes wrong no one will be there to help you. I have had a series of problems with my Diaguns, not to go into the details but lighting does strike twice. However, if it wasn't for the user friendly and excellent customer services that was provided by Peter I would have purchased a different product. You don't find many Peter's about so he is invaluable to the company. I applaud you for coming to my house when it all goes wrong. I thank you personally. Regards Muhamed

  • *****Excellent Launch X431 Diagun

    By Malcolm

    Without doubt this is the best bang for bucks I've bought in a long time. Super fast and super efficient. Staff are very knowledgable and friendly. I'll certainly be buying other products from them in the future.

  • *****Genius Piece Of Kit

    By Issy Khan

    I am mobile diagnostic technician...and purchased the Diagun 6 months ago. thus i am writing this review after 6 months of continuous use.

    The Diagun covers almost all known car makes and plus 10-15 other makes you may never see or use!! such as Holden

    but covers all the common known marquees such as VW, Audi, BMW, Mercedes, Vauxhall, Ford, Honda, KIA, Fiat and Toyota just to name a few....so it has a vast coverage of vehicles!!

    It is very simple to use including programming and special functions as all instructions are guided on screen...i have used this tool to code injectors in Vauxhall and Ford vehicles, i have adapted the clutch in a semi auto Toyota verso and calibrated Ride/ suspension height in a Range Rover sport.

    IF ANY HELP IS REQUIRED IN USING THIS TOOL, I CAN PERSONALLY HELP.....ask Diagnostics4U for UK Diagnostics contact details.

    the amazing functions and diagnostic abilities is complimented by its size....this is a super computer in the palm of your hands!!

    with the constant available updates, this makes this tool a must have choice!!! RECOMMENDED TO ALL GARAGES AND INDIVIDUALS A++++

    Call UK Diagnostics: 07904 371 888 in Greater London area for all diagnostics including Remapping - DPF Removal - Airbag Crash Data & more

  • *****Diagun x431

    By Active Autos

    I have been in the automotive business for near on 25 years. I have had several diagnostics machines, the last one I had was the Snap on Solus. I was informed by my snap on rep that it was the best on the market, hence the high price of the machine. After 2 years living with this machine I found it good on some vehicles but could not link up to most...I decided to purchase the DIAGUN X431 after a college of mine suggested it.... Well what a bit of kit.... This machine is compact and very user friendly. I have had the machine for 3 months now and it has worked on every car... BRILLIANT! I would also like to mention the excellent customer service provided by Diagnostics4u, especially to Mike who is always happy to help.
