XTOOL D8S Bidirectional Scan Tool 2026 Upgraded Ver. of D8 Scanner, AI-Assisted OBD2 Scanner Diagnostic Tool, Topology Mapping, 42+ Resets, FCA, CAN FD&DoIP, All System Scanner for Car, 3-Year Update

XTool D8S Review: I was in the market looking for a Bi-Directional Diagnostic Scanner for my DIY car garage. I knew what cars I had at home and didn’t want to pay extra for bells and whistles that really wouldn’t apply to my needs. I did my research and came across the XTool D8S. For me, it seems so far to do everything I need on my cars and a whole lot more. Below are the pros and cons that I have encountered (so far) from this great device. First, while in the process of doing my research for a Bi-Directional scanner I contacted a couple of different companies’ support teams with various questions about their products. XTool’s support team did such an excellent job replying to several of my emails very quickly and with prompt and detailed answers. They gained my trust, and I felt that this was a company that would stand behind their products. Secondly, the 3 years of free updates that comes with the device and the 2 years of warranty was also a big selling point for me. This way, I knew that if I had issues with the software or hardware, their support team would be there and provide help down the road (if I needed it). Lastly, after I received the D8S, I realized how sturdy and well built the device is. It has a large 8-inch screen, a fast Android 10 operating system, new topology layout, a Quad core CPU, and software that will pretty much do “almost” everything a home DIY car mechanic would need from a Bi directional scanner. I ran the auto scan and found a few errors on my machine. I have included a photo of it. This device really can compete with scanners twice its price and hold its own and I love the Topology structure system representation in the software. I have created a lengthy 20+min informational “box opening” video review of the device (uploaded in Video section of product page with NG33 name). Take a look at it if you are in the market for an auto diagnostic scanner. I do not think you will be disappointed with this D8S model or other XTool products. Also, if you have any questions about what tests this scanner can complete on your specific cars, do not hesitate to contact their support team via email and ask your questions before making the purchase. I will update my review as I further test this product in the future, with regards to how it holds up over time and my experience with the company. So far, it has been great!

Excellent scan tool with an amazing number of diagnostic capabilities. It boots fast and then gives 2 options to connect to the car. You have the choice of auto scan or manual selection and they both connect promptly. The first time I used this tool I let the Xtool do a full system scan and then used the topology map to point me in the right direction and subsequently diagnose an ac problem on a 2017 explorer. The second time I used the tool I recorded sensor outputs and then graphed them to diagnose a "crank no start" issue on a PT Cruiser. The recording function and graphing function made it easy to pinpoint the sensor issue that was preventing the vehicle from starting. The diagnostic capabilities of this D8S are extensive and I feel that I bought and excellent tool at a fantastic price. The interface is easy to use, and I appreciate the straightforward screen choices and inputs. I returned a competitor's scanner before buying this Xtool D8S and I am much more satisfied with this significantly less expensive scanner. I will be buying more Xtool products in the future.

I was quite surprised at the amount of flexibility this computer offers in terms of total functions that can be played with. You can alter the VIN, the internal odometer, idle RPMs for the motor, and many other things. Great quality overall in terms of features. I’ve tested the connectivity on a 2003 Tahoe, 1999 Tacoma, 2009 Silverado, 2014 Camry, and 2014 Volvo XC60. All of these worked fine with the scanner. Diagnostic capability varied largely as newer cars and trucks typically have many more electronic features available to be tested. Definitely quite expensive but worth the money if you need a lot of keys programmed or get specific information of spark plugs misfiring or total health of individual components. Will be testing and altering this review further down the road as I continue learning how to use this scan tool. One thing to add: Update the scanner when you first receive it. I believe the scanner has about 280 updates when I first turned it on. Connect to WiFi for this. I ended up using all of my 10GB of hotspot from my phone and it was quite slow and limited on updates I was able to download with that. Edit: I had a constant TPMS error in my Volvo. it always stated that all 4 tires were at low PSI since i bought it, despite all tires being aired up near capacity. This device allowed me to reset the TPMS and reset the error code. Error light is now gone.

Diagnostic tool: XTOOL D8 (Wired Not Bluetooth) Test Vehicle: 2004 Yukon I bought my XTOOL D8 some time before this review, and that was so I could test it enough to do a proper review. I was not in a position to test it on any issues but was able to go through it enough to see how it will be better at diagnosing any issues then a basic OBD II code reader can ever do. The device was on sale is what made my decision, finally got to that point that I felt I would need one soon and bought this XTOOL D8 These tools are hard to find exact information for the reason that so many vehicles and different configurations are out there. Though for the functions they should have a better break down and description detailing its full capabilities for that option. What it can do as well as cannot do with a particular function. The first time I used it, I was impressed – to see all the modules that my truck has. Becoming more familiar with the menus and recommend to anyone to first explore the tool menu and functions regular so when an issue does arise you spend less time trying to navigate – it is very detailed in what you can see with your vehicle. I would have liked more programing options or special functions at this price like being able to READ more vehicle Pin Codes for adding extra key but probably why the higher models are more expensive. Over-all I am happy with my XTOOL D8, I'm sure it will pay for itself. RATING: Cost: 4/5 Construction: 5/5 Support: 4/5 Function: 5/5 Quality:5/5

I'm the family mechanic and I pride myself on my ability to properly troubleshoot and fix my families cars while saving cash and ensuring the job is done right the 1st time! I purchased this tool primarily because I needed to clear stored learned data in the PCM/ECM on a 2006 Honda Civic EX (Sedan), but also because I've been wanting a bi-di diag tool for years! I called multiple shops in my area, including the Honda dealer to get this simple task completed. The two independent shops I called could not help me. One said their "Launch" brand diag tool was broken and awaiting warranty repair. The other shop didn't even want to attempt the job since I had done a lot of recent service work on the vehicle myself. The dealership service department claimed this year/model Honda didn't support such a feature. They wanted $200.00 just for a system diagnostic before they would even recommend a solution. Nothing but incompetence and I was beyond irritated at this point and done asking others to do the job. I found out about XTOOL through various YT car channels I follow as well as recommendations and discussions on vehicle forums. I decided to give it a shot after reaching out to XTOOL sales asking which model supported the feature I needed for the PCM/ECM stored data reset/clear on a Honda. I received a response within a few hours and purchased the D8. Out of the box, the system came nearly fully charged and was easy to get setup. I downloaded all the updates, which took about an hour (over 100 packages!). It connected straight up to my Honda and communicated with the PCM/ECM without issue. Right away I noticed this tool is fast! It scans fast and the menu navigation has little to no hesitation. I was able to quickly access the feature I needed to clear the data, literally took a few seconds to sort through the menu system and follow the process. Afterwards I was able to properly execute the idle relearn (10 minute procedure after vehicle is warmed up) and verify it was successful by monitoring the live data on the D8. All told, about 15 minutes of actual work at the vehicle. About 5 minutes to warm up the car and clear the data and another 10 minutes to complete the idle relearn (I was quoted $200 from the dealer for something that should take 15min!). The Honda Civic now idles smoothly where it should (670RPM) and shifts into D and R without surging. No more 800+ RPM idle, no more 12-15mph creep while in D without touching the gas! This is an amazing tool for the price. Nearly every feature I have used so far works great. Keep in mind not all vehicles support all features or actuation tests so your mileage may vary. That being said, most late model vehicles are heavily computer controlled, this tool will most likely be able to handle the troubleshooting task you need. Support for older vehicles (1997-2002) will most likely be minimal. I tried the tool on a 2000 Acura RL and it had very limited capabilities. Not because the tool is bad, but because the vehicle is so old. So far I have used this tool on a 2006 Honda Accord (4dr), 2008 Acura RDX, 2007 Toyota Tundra, 2016 Toyota Corolla, 2006 Nissan 350Z, 2014 Dodge Ram, 2006 Honda Civic EX (4dr, one in my story), and 2000 Acura RL. I have been able to communicate with all the vehicles without issue. I did notice some odd behavior on the 2000 Acura RL, but I suspect again because that vehicle is old, back when OBDII ports were still a new thing. In summary, give this tool a shot! I think you will be happily surprised. With a few more uses, it will more than pay for itself!

This Scanner operates in a simple, straightforward and intuitive manner, which is all the more amazing when you consider its extensive diagnostic capabilities. And its storage Case is ruggedly constructed with thoughtfully designed compartments for the included accessories. I did encounter a minor issue with connecting the Cable to the OBDII-16 Adapter, but a quick email to the manufacturer and they were able to confirm the problem was a defect with the Cable, and a replacement Cable was sent immediately. I can't emphasize enough the prompt and professional response from Cynthia and the Customer Support staff at XTOOL. I'll admit that I was initially hesitant in purchasing this Scanner, because at this price it is not an "impulse buy", but after just a few uses I was amazed by its diagnostic capabilities and ease of operation. When one factors in the excellent Customer Support the decision to purchase is made simple.

As a professional automotive technician, I’ve owned and used several XTOOL products over the past few years. Up until recently, I would’ve gladly given this particular scanner a solid 4 stars. I got it at a fair price and initially used it as a companion to my Autel Ultra, which I rely on daily in a shop environment. Out of the box, the scanner felt promising. The build quality seemed decent, with textured grips that felt comfortable and ergonomic. While the screen resolution was noticeably on the lower end, the interface itself was responsive and smooth to navigate. I used it regularly for everything from system scans to output control testing and even dabbled with its ADAS capabilities—though I’ll note that those functions are quite limited compared to premium-tier tools. Where this scanner really shined was on VW/Audi platforms. It handled secure gateway access impressively well and allowed me to reset airbag modules—even in situations where my Autel had failed. The topology mapping was another standout feature that helped with system overviews and workflow efficiency. But unfortunately, things took a serious turn for the worse. After just a few months of very light use, the scanner abruptly stopped communicating with any vehicle. No matter what I connected it to, I kept getting a prompt to “connect to vehicle” despite the cable being securely plugged in. I even tried a replacement cable—same issue. I reached out to XTOOL product support and, at first, received a reply asking for photos and a detailed description of the issue. I responded promptly with everything they asked for—but then the communication went completely dark. No follow-up, no support, and no resolution. By the time I realized they weren’t going to respond, my support window had closed. Despite numerous follow-up emails, I was completely ignored. Feeling frustrated and out of options, I decided to open up the device to inspect the issue myself. What I discovered was deeply concerning: the OBD-II port had completely separated internally. Even worse, the two mounting nuts (which the OBD connector screws into) were not secured with washers and were instead mounted directly to the circuit board. This is a clear and dangerous design flaw. With no reinforcement or isolation from torque or stress, it's only a matter of time before the internal connection fails—as it did in my case. I take very good care of my diagnostic tools, and this failure happened under extremely light usage. What’s more disappointing than the hardware issue itself was XTOOL’s complete lack of support or accountability. I wasn’t asking for much—just a repair, a replacement, or any kind of meaningful response. I would have gladly paid to have the unit repaired if they’d been willing to work with me. But instead, I was left with a bricked tool and radio silence from the company. As someone with an engineering background, I can confidently say this failure was due to a weak and poorly thought-out internal design, not user error. I’ve been a loyal XTOOL customer for years, but after this experience, I can no longer recommend their products to fellow techs. I’ve since replaced this unit with a Launch X431 scanner, which has proven to be a far more reliable tool from a company that stands behind their product—and at a lower price point, no less. If you’re considering this scanner, I highly encourage you to look elsewhere. I don’t know how other models from XTOOL hold up, but the company’s unwillingness to support a loyal customer or take responsibility for a known hardware issue speaks volumes. It's one thing for a tool to fail—these things happen. But it’s how a company handles those failures that truly defines them. Sadly, XTOOL has shown they’re only around for the positive feedback—not when it really matters. I wouldn’t want anyone else to experience what I did.

This XTOOL D8 scan tool is highly capable, and especially so in its price range. It had no problems connecting to and diagnosing GM vehicles here, and offers a wide array of special functions as well. Diagnostic code support is thorough and logical. Live data monitoring works very well and reasonably fast. Overall uisability is very good, the user interface is well designed and responsive, the unit itself is performant, too, I experienced no sluggishness or excessive wait times even for complete diagnostics. Updates are released regularly, adn the process itself couldn't be simpler. Bonus points for making updates individually configurable, which means I don't have to download everything for all the brands and models I never see, and it's even asynchronous, I can change my mind and add/remove to/from the list of updates to be applied even during the process. Finally, correct English terminology and grammar is one of my pet peeves with other products, and this one passes with flying colors, I found very few typos across the entire gamut of labels and messages. As to negatives, there are two small things worth a mention: first, turning the scan tool on is a bit weird: technically, a long press of the power button should do it, but sometimes it didn't happen and the unit took a few short and long presses to finally come to life; and second, some functions are buried so deep in the menus that getting back to the main screen takes 5-6-7 or more taps on the back button, and there seems to be no other way to directly return. All in all, this is a great, versatile and performant tool that is a very good value for the money.
