OBDLink® MX is a budget-priced, pocket-size Bluetooth OBD-II adapter for all OBD-II compliant vehicles (except hybrid or electric vehicles). It can be used as a diagnostic scan tool, trip computer, logger, and real-time performance monitor. OBDLink® MX surpassed performance in every competing Bluetooth OBD-II adapter, delivering 300% more data samples per second. Its BatterySaver™ sleep mode allows the adapter to stay plugged in continually, without draining the vehicle’s battery.

Unlike the vast majority of Bluetooth OBD adapters, which constantly broadcast their presence and use an easy-to-guess 4-digit PIN, OBDLink® MX utilizes a unique multi-layered link security mechanism, eliminating the risk of unauthorized access. OBDLink MX’s support of the de facto standard ELM327 command set, makes it compatible with tons of third-party OBD software and mobile apps.

OBDwiz and OBDLink app, included with OBDLink® MX, allow you to:

  • Turn off the check engine light, and erase stored diagnostic information
  • Read and erase stored, pending, and permanent trouble codes (both generic and manufacturer-specific)
  • Access freeze frame information
  • Display, graph, and log 90+ real-time parameters
  • Create custom digital dashboards
  • Measure and display fuel economy
  • And much more!


  • Maximum vehicle coverage (Verify your vehicle is OBD-II compliant)

This is ONE you need for a Windows 10 laptop scanner. 5+!Review by Anonymous [Amazon Review]
First I tried an Autel direct connect: Very solid, lots of features, but the software froze up the second time I used it: bye!

Then I got a Veepeak wifi scanner for Windows. It was a very tight fit (too tight), hard to connect, and then all I got with my expensive OBD Auto Doctor software was "Invalid OBD Standard"....bye.

Then I bought this. First I tried it with OBD Auto Doctor and it paired and worked just fine. !!!!

The I downloaded their OBD MX software from their site, ****SAVE THE LITTLE PIECE OF PAPER WITH THE LICENSE CODE*** that comes with the scanner. The scanner paired to my Windows 10 laptop fine, but the program itself would not connect via Bluetooth UNTIL I changed the COMMUNICATION TYPE setting to the first checkbox for USB,BluetoothRS-232 AND also changed to COM PORT 6, and then everything clicked right in.

Frankly, the OBD WIZ app was as good as the expensive OBD Auto Doctor in my opinion, for everyday drivers. I am sure there are differences that mechanics would notice and so on, but I don't understand half the stuff they scan anyway.

In short, this scanner and their FREE software is all you need for a very nice Windows 10 laptop auto code scanner. And yes it does clear Check Engine Lights -CEL- codes. Also, the dashboard gauges are quite nice. (Posted on 10/20/2016)
Works as intendedReview by Zach [Amazon Review]
I have had no issues with the device and it has already been put to work in a handful of different vehicles. The communication speed between the device and phone is blazing fast. If you use an application like Torque Pro the device will read realtime data and display it with more accuracy than the actual gauges in real time.

This device is only as good as the software that supports it. It does come with free software that works well, and other apps are available on the marketplace that may work better with your particular vehicle (Forscan is an example).

The only reason I rated 4 stars instead of 5 is that you have to forget the device every time you disconnect from it. It gives a new code when you hit the bluetooth connection button so it won't 'remember' your phone. This is a minor inconvenience but it is still an inconvenience. Perhaps ScanTool can introduce a watch battery powered memory much like how your computer remembers Bios settings when it is turned off?

Hope the review helps, I am pleased with my purchase. (Posted on 8/15/2016)
Great tool for the novice or the pro.Review by G. Thomas [Amazon Review}
I am a professional auto technician with access to several high end scan tools. I got this tool to use as a quick preliminary check tool before breaking out the slow to boot and cumbersome "big gun" tools but I find myself using this tool instead of the high end tools because of it's speed and coverage. Great tool!!!! (Posted on 8/15/2016)
GREAT, GREAT, GREATReview by Jeremiah Mauricio [Amazon Review]
I bought this with some reservations, as my wife's 2002 Subaru Forester doesn't function on some inexpensive OBD II readers. The readers don't see the car, and I don't know why some do and some don't. However this works perfect, I keep it in the car and use the software to play with the digital dash. I can read and clear codes, and leave it plugged into whatever I'm driving just to have it with me. Friends have borrowed it and it is awesome.

I also race and use other apps with this and it works perfect! This might be one of the best tools I have bought in the last 5 years. (Posted on 8/15/2016)
Top Shelf OBD-II Bluetooth ToolReview by Carlos Thomas [Amazon Review]
I've tried a few of the cheaper items before finally settling on this. The OBDLink tools are known for being good - I actually also own the SX. I wanted something to use with my phone for checking stuff on my vehicle, but the cheaper items were slow or gave issues with the electronics in the vehicle. Since I've used this there have been no problems whatsoever.

My advice would be to use this along with another tool such as Torque. While the original software gives EXCELLENT reports, third party applications seem to work faster with the dashboard items. Other than that one hiccup the tool is just that: EXCELLENT. (Posted on 8/15/2016)
Worth every pennyReview by John M. [Amazon Review]
Indispensable tool for the DIYer! Paired with a paid app that includes an engine temp alarm has saved my p38 from catastrophic overheating while working out cooling system bugs. Possible app related, but maybe 1/20 will not connect via bluetooth to my tf101 tablet and I must take the extra few minutes to resync. Worked well on 3 vehicles so far (2002 Range Rover, 2000 Jeep Wrangler, 1998 Hyundai Elantra.) (Posted on 8/15/2016)
OBDLink wins.Review by M. Cole [Amazon Review]
I had difficulty deciding between the Bluedriver, and the OBDLink. After testing both, I hope the review below may help you.

The ability to use iOS is nice, however, the OBDLink coupled with a $63 Android phablet worked better in my situation, as described below.

The layout of the included OBDLink software is excellent. I can easily see many live parameters on one screen, without jumping through hoops and dozens of clicks to display them.

With the Bluedriver, I was disappointed with the layout of the real time live data screen. It is nice to have the option to show the graphs on the main page along with the data, however, it was laid out in a semi-confusing manner, hard to tell at a glance which line the data referred to, with no obvious visual breaks between lines. As a mechanic, I prefer the capability to show many items at once on the page, with the field description at the left, and the data on the right. When the graphs always included, it really limits how many fields can be displayed at once. Some of the parameter descriptions were vague, and hard to identify when on the data viewing screen, although they were clearly labeled on the parameter selection screen. It was especially hard to identify which O2 data I was looking at, and which sensor it was for.

Being limited to the Bluedriver software was a large reason I selected the OBDLink device. I like the functionality and layout of the ODBLink software, and open compatibility nature of their setup. There are some custom written programs that work with ELM 327 that really do much more than either OBDLink or Bluedriver by themselves, and the ability to utilize those programs, like Forscan, was huge for me. I can get access to seemingly every parameter on my 2012 F350 with the OBDLink and Forscan. Really a dizzying array of data.

Since I am not set on using iOS, this OBDLink was a great solution.

One thing that would make these devices even better would be bi-directional control. (Posted on 8/15/2016)
Saved me a trip to the dealer!Review by Tom Aiken [Amazon Review]
I use this with a nexus 7 tablet for monitoring my 6.4 Powerstroke with torque pro mostly, but I was able to use the forscan app as well to diagnose an ABS light on my dash, saving myself a costly trip to the dealer. I also love that I can use it on my girlfriend's Cadillac STS as well which is a big plus because maintenance on it is just as expensive as my diesel! As always prime two day shipping was great.

Works great with LinuxReview by Abu Ari al Saba [Amazon Review]
It worked great with my 2003 Honda Accord and Odyssey and my 2001 Corvette. I am running Ubuntu 14.04 LTS Linux on a Asus laptop with Plugable Bluetooth adapter. Because I run Linux, I used OBD Auto Doctor. OBD Vehicle Diagnostic scanner is available for free on Ubuntu Software Center but I wasn't able to get it to work with Bluetooth. There are plenty of instructions on the web on how to adapt it to Bluetooth but it didn't work. Free wasn't worth the hassle. OBD Auto Doctor, at $50.00 for the mid-tier version, worked immediately with the Scan Tool. Bottom line: if you are using Linux, this hardware works great, as long as you can get Linux software that works; OBD Auto Doctor works great with Linux. The only reason that I didn't give it the fifth star is that it would have been even better had it been even lower profile. (Posted on 8/15/2016)
Best Automotive Product I've Ever Purchased!Review by Dan [Amazon Review]
This tool is amazing. It syncs great with every phone I've had since purchasing and the read and update speeds are incredible. Personally I prefer using Torque as app, but it gets used everyday to monitor my Duramax. Everyone who sees this is somehow amazed it send the info to my phone. Customer Support has been great as ScanTool replaced mine after over a year when it started to have issues. No problems since. I can not recommend this enough. (Posted on 8/15/2016)
The software is good enough, or you can try some of the ...Review by Jane Smith [Amazon Review]
The software is good enough, or you can try some of the alternatives on the Google Android store. Worked on all three of our cars (Italian, American and Japanese) with no problems. 0-60 tests were less than effective as it only was capable of 6 queries in 5 seconds on the Italian vehicle, which has a low-4 second 0-60 (registered 7, while g-tech was 4.5 and car-and-driver magazine was 4.2). All other functions worked flawlessly - including an accurate reading on a fuel cap error (caused deliberately). Probably worth it over the lower version for versatility. (Posted on 8/15/2016)
Did more than I expected.Review by Jesse T Sanders [Amazon Review]
It works beyond my expectations. I used it to create a baseline for Mustang'a O2 sensors. Pulled it all into a spreadsheet. Also I have improved my gas mileage by 2 to 3 MPG using the monitor. Great product. (Posted on 8/15/2016)
1st tool out of my toolbox on a customers car/truckReview by Marty the Mobile Mechanic
Hi, I am a ASE Certified mobile mechanic in Santa Cruz Ca.for over 35 years. This OBDLink MX blue tooth OBD 2 reader is the 1st tool out of my pocket when diagnosing my customers cars or trucks. The scan is very fast and the PID view is so awesome with sometimes two screens full of precious information and "Freeze Frame views.
Sometimes my customers are in their offices/homes or out of town and I am able to do a quick "screen shot" of the Trouble Code screen and the PID screens, Then, I instantly text the OBDLink "screenshots' to their smart phones. So easy to explain ..."a picture is worth ten thousand words". In just a moments time, my customer sees this beautiful, professional text/screenshots of their "check engine light" problems on their smart phones.
OBDLink also features a "web lookup" that gives more information to "share" with the customer via texting.
I never need to bother them in their workplace/ (often I am out diagnosing the vehicle in an office parking lot)
The customer just looks at the screenshots/ information and usually gives me the go ahead to do the repair work (no "face to face" necessary) ..and they can refer to the OBDLink info as a permanent text "record" to show their husbands/partners or daughters text the info to their Dads for the "old man's" approval...
This saves a whole lot of paperwork...and a text is a legal document.!!
I trust the information OBDLink MX gives me and my customers....and they give me lots of business...based on this incredible scan "tool"
..Thank you OBDLink MX
. You guyz at OBDLink rock!!!!

The bluetooth you are having without bluetoothReview by Matt
Before buying make sure you contact ScanTool and find out if your device is supported. This will not work with Apple products. It will not work with some versions of Android/ Samsung. It will not work with T61 laptops. Looking for support? Forget it. They tell you to look at the forums. This product is a nice idea, too bad no customer service and that the product does not work with all Bluetooth...
May 21, 2013 4:12:58 PM

RESPONSE: MX Bluetooth does work with the vast majority of Android phones & tablets, although it doesn't work with the iOS.

We purposefully handle all of tech support from our forum because we find this to be more valuable. When customers have the similar questions, posting in a thread allows accessibility to answers any time of day or night. It is a wealth of information and our engineers are excellent at responding quickly to individual concerns. (Posted on 5/21/2013)
No supportReview by Grumpy
If you email them for support and you get an automated response directing you to the forums for amazing answers to amazing issues by amazings techs. Sorry but I have had to much amazing bad advice already. No staff = no purchase.
-- May 6, 2013 12:21:54 PM

RESPONSE: We do not have automated email responses, our staff answers email multiple times per day. We handle all tech support from our forum purposefully to be of more help to the customer. Since there may be many customers with the same question, the forum allows you to run a search and have more access to information even when our offices are closed. (Posted on 5/6/2013)
Good but not that good. Review by Zenya
The native application has problems connecting to the OBD2 device. Doesn't "sleep" as advertised. Drained my battery completely.

Really happy with OBD LinkReview by Steven
This makes my Peake Scan tool a joke.
With OBD Link I was able to see which precat 02 sensor was bad and why. Also found a bad t-stat on my Mini. It's already paid for itself 3 times over. I'll though out the POS Chinese adapters that I bought that worked only for a short time.

AmazingReview by James Millar
I'm a professional mechanic, looking for a small, handy device to supplement our Snap-On scanner

After extensive research, I chose the OBDLink MX. I needed something fast, compact, and reliable, and everything I found suggested this was the best.

Since receiving it, our full-function Snap-On scanner has stayed in its box - the OBDLink MX is faster and more convenient. I'm using it with Torque ( pro, but I started with Lite and it worked great).

ScanTool.net is great too - I bought the tool at full price, then they refunded me $50 because it went on sale before my payment cleared, That was far beyond my expectations, and has completely sold me on their customer service.
