  1. I was after a bluetooth obd2 scanner for a long time but the bluedriver is the one I went for. Well worth the money and its something I just keep in my car nowadays. It works on the majority of cars and its so simple to use.

  2. For ordinary users, Bluetooth OBD scanners are more suitable. They can also do full-system diagnosis and also provide special tools like Reset BLEED, Reset TBMS, Reset TDPF, Reset Oil, Immobilizer/Keys and so on. EZcheck and EasyDiag are both good choice.

  3. Your Comparison Check-List Pros/Cons Criteria is not the same per each model…it’s all over the place like a scatter-brained blonde.

    You ought to respectfully take the time & do an APPLES TO APPLES Comparison.

    Like ECU Reprogramming versus other Models with ECU Programming for example.

    Blondes are great when you’re out drinking with the boyz & getting smashed but feckless in the real-world & not even worth keeping around sober even if they give a good BJ.

    This article is worthless.

  4. Thank you for your great information.
    I’m from Libya and I’m an industrial instrument and control engineer, I have good experience in dealing with programmable test equipment. I’m going to open workshop for cars with diagnosis tools, I want my workshop is the best and I’m still confused which is the best scan tool for me!
    My workshop will focus on Germany cars like Mercedes Benz and BMW, also modern asian car , So which the best scan tool is suitable for me, I don’t care for the price?

  5. Hi
    I run an OBD1 car, a 1997 BMW E36. Is there any diagnostic tool on the market for this? I live jn the UK and am a keen home mechanic.

  6. I Tim,I live in the Caribbean we mostly have Japanese cars here,what would you consider a good tool to have for these cars,to read airbags an and lights etc, thanks.

  7. I’m confused to select one of the professional scanner for my workshop, I don’t for modules update but it’s important to be able to reprogram some part like if replace ABS.
    Also, it’s important to be affordable, so witch scanner (Autel MaxiDas DS808K or Launch X431 V+ or….) can you advise!

    • You will find that the functions offered by Launch X431 V+ are about the same with DS808K. They offer various service functions for technicians and work reliably. But the prices are a bit different.
      Then if you want to save some bucks, consider DS808K.

  8. I am a Independent Repair Technician that wants my own scanner for home and my neighbor that is versatile (works on many cars and as many functions as possible) but has LIFETIME UPDATES. Not looking for a second career at home but friends/family seem to have car issues and I want to help them if possible. What you suggest under or around $500 ? I have looked myself silly at Autels , Foxwells , Launch and even Zurich can’t seem to make a decision

  9. I am a independant car repair agent and i want to have my own scanner. they vehicles that I will be dealing with are europeen and asian vehicles. toyota/nizan, kia, Mitsubishi etc. what
    scanner will be most appropriate?
