  • Great tool for DIY & shops on a budget, great support, 3 years free software upgrades
### Long Review but worth the time to read ### ### - Summary - Really good tool for DIY & Shops on a budget, great email, phone, and remote screen sharing customer service/support, 3 years free software upgrades ### ### Detailed Review #### If you are a DIY mechanic looking for more than a basic ODBII code reader or have an automotive shop and not looking to break the bank, the XTOOL D8 is a good option and something you should consider. I saw a review for the D7 last year and was really impressed but could not justify the costs at that time. Stumbled across a discount offer (saved 25-30%) on the D8 a few weeks ago that was too good to pass up. There was also 3 years of software updates included (other products in the same space charge upward of $200 per update..yikes) with the purchase! If you have never used a pro level diagnostic tool it can be a little intimidating, but the Xtool screens/displays/menus make it easy to run automatic scans and jump into specific functions based on your needs. Depending on the age of the vehicle and on-board features, you can complete and control all kinds of tests/functions from the D8s menu system. Examples I have 4 different cars ranging from 2002 to 2020. While the computer on the 2002 may not have as many functions as the 2020, with the D8 I have full access to all the available functions/features allowed by each car. The D8 helped me we diagnose/confirm the issue with a door lock on my 2014 was the switch and not the actuator motor. It also helped me monitor the trans fluid temp while performing a transmission fluid service on the sealed transmission in the same car. While there are other ways to monitor the temp, they are less accurate and require additional steps/procedures. Key reprogramming/replacement on newer cars can be expensive. The dealers charges are not cheap, but with the D8 I can complete the replacement key programming & sync process. For use/pre-owned car owners, do you REALLY know that the dealer or seller gave you ALL the keys/phoebes sync with your cars? With the D8 you can complete a process to remove all PREVIOUS keys that were synced with the cars and only re-sync your keys/phoebes you have in hand. While the features of the D8 are important, I believe XTool's customer service/support is what separates them form other competitors with similar products. I have used their email support but have seen they have options for phone/web/remote control support (using TeamViewer on the tool). Even before you buy, you can send them questions via email or Amazon about what the tool does and what features it has. They asked for my VIN #s to provide more accurate information and replies usually came within a day. Even after I bought the D8 and had questions, they were very responsive with replies. I have read review about "similar" products and a common theme with those is that customer support is lacking, and responses are slow or not at all. Having a tool like this may be a luxury for some but in my case its paid for itself in repair diagnosis/cost savings. It even helped while looking for a used car recently. Any car we looked at, I plugged in the D8 and ran a quick scan to check codes. I could even tell if the codes were cleared recently without the emission/smog drive cycle being completed (red flag). Depending on the age of the car, I was also able to quickly jump into running some deeper tests/scans to make sure everything was in working order. Lets just say that there were more than a few cars we walked away from because of the info provided by the D8. ... show more

  • Awesome Capability and ease of use
I bought this tool specifically to fix a hybrid car problem. My 2005 Prius had the dreaded "triangle of Death" . For those who do not know, this means the car will not work in any way, but does not specify wether the problem is mechanical, electrical or both. With the Xtool D8 I hoped to find and fix the issue, and I was not disappointed. The D8 immediately connected to the car network, and presented several codes. the interface was great, and easy to click through the problem codes to get advanced diagnostic data, live and freeze frame data from the car canbus network, and help to use my skills to find and fix the root cause. The battery control computer was found faulty, and with some digging and visual inspection I was able to replace the part, and my Prius was back on the road. Since that time the D8 has helped me find problems in many cars and Trucks. from resetting transmission 'learning' mode to smooth out shifts, properly bleeding abs brakes, to adjusting fuel pressure and A/F ratios on light diesels. Even Identifying the notorious VTEC solenoid issues in Honda engines and Shift Errors in later GM truck transmissions. (Change the fluid often!) This tool has paid for itself many times over with advanced diagnosis saving the typical Parts Cannon Approach to fixing todays sophisticated automotive systems. While I am not a professional shop, I am considered by many friends and famiy to have advanced mechanical skills, with over 40 years of auto repair experience. In short, this is a very sophisticated tool that should definitely be added to any serious enthusiast toolbox. It has programmed keys and remotes for several cars, which alone is savings well beyond the purchase cost. I have paid a lot less for other tools, only to find they were worth it by doing a lot less. My only 'challenge' is that I wish I had bought the wireless option, but that is on me. Xtool has provided excellent customer support with software updates to cover all the latest developments in tech, as well as help me better understand how to use the equipment. I thought quite a bit about spending this much on a tool for my issues, and look back and consider one of the value purchases I have made. TL,DR: Great Product. Great Value! Amazing Customer Service. ... show more

  • Long update but well worth the wait.
Scanner is a little tricky to use, and takes a long time to download all the updates. That being said, I still give this a 5 star review because it is the only one I found that actually cleared and calibrated the electronic parking brakes on my car after I replaced the worn down original pads and rotors. It works fast, it is smooth in operation, and connects easily to both of my vehicles. Highly recommend it. ... show more

  • Exceptional Speed and Professional Depth
Whether you are a professional tech or a serious DIYer, the XTOOL D8S is a powerhouse that punches way above its weight class. After putting it through its paces in a busy shop environment, here is why it deserves a full five stars: Performance & Speed The first thing you notice is the hardware. The D8S is incredibly snappy; booting up and scanning modules takes a fraction of the time compared to older tablets or entry-level scanners. The touchscreen is responsive even with shop gloves on, which is a huge plus when you’re mid-repair. Deep Diagnostics & Bi-Directional Control The bi-directional capabilities are flawless. I’ve used it for everything from fuel pump tests to EVAP venting and cooling fan activations. It talks to almost every module on the vehicle—not just engine and trans, but ABS, SRS, SAS, and even body control modules. Key Programming & Coding The ECU coding and key programming features are where this tool really pays for itself. It handles many advanced functions that usually require a dealership-level subscription. For common maintenance, the 36+ reset functions (Oil, EPB, SAS, DPF, etc.) are intuitive and fast. Build Quality It feels rugged and "shop-ready." The battery life is impressive—it can go through a full day of diagnostic work without needing to be tethered to a charger. Pros: Massive Vehicle Coverage: Handles domestic, Asian, and European brands with ease. CAN FD & DoIP Support: Future-proofed for newer vehicles without needing extra adapters. Frequent Updates: XTOOL is constantly pushing software improvements and new vehicle data. Value: You get features usually found in tools costing twice as much. Highly recommended! ... show more

  • A Mechanic Shop in a Tablet!!!
I consider myself a pretty good DIYer, and for years I've been stuck between cheap code readers that do nothing and professional tools that cost thousands. The XTool D8S has finally bridged that gap. It’s an OE-level bi-directional scanner at an excellent price. It has paid for itself multiple times over by allowing me to perform dealer-only maintenance and correctly diagnose issues I would have otherwise guessed at. If you’re serious about working on modern cars, this is the tool to get. The 3 years of free updates were a huge deciding factor. XTool is constantly adding new vehicles and features, and I love that I don't have to worry about renewal fees for three years. The updates themselves are easy, done right over Wi-Fi. The 8-inch screen is bright and seems durable. My only real gripe is the speed. It’s not slow enough to be frustrating, but the initial boot and sometimes the loading between deep diagnostic menus can feel a bit sluggish. (Note: This is a common trade-off for the price—you’re getting the software function of a $2,000+ tool on the hardware of a lower-cost tablet.) Of course is not a Snap-on Solus+ fast, but you’re not paying Snap-on money. ($3600) The XTool D8S is, without a doubt, the best investment I’ve made for my garage. It eliminated the guesswork, gave me the confidence to take on more complex repairs like coding a new occupancy sensor on an a friend’s Infinity Q60 and programming my own key fobs on my G37. It brings professional-level capabilities like Topology Mapping and true Bi-Directional Control into the hands of the dedicated DIYer. I highly recommend it. ... show more

  • Good price for what you get.
This is a great scanner and I’ve used it to program keys for a Mazda cx7 which has almost paid for the scanner in savings. There are some problems with this scanner, does not work well with every vehicle, there needs to be a battery voltage monitor and oil reset can be hit or miss. The menu isn’t the most user friendly and can be a bit confusing. The company has been very good with communication and is quick to respond. I’m a licensed and certified technician and I use this at work, there are times when I have to grab my old autel scanner but then there are times when the xtool does better. Overall this is a great scanner for the price, it needs some work to be better but the company seems to be on top of the updates. ... show more

  • A fast, reliable, and well‑supported diagnostic tool.
After testing the XTOOL D8S across several vehicle brands and model years, I can confidently say it is a fast, reliable, and highly capable diagnostic tool. The interface is smooth and responsive, and the overall speed of the device makes everyday diagnostic work considerably easier. As the owner of a previous XTOOL model, I can say that the D8S is clearly a step forward. The improvements in speed, interface responsiveness, and overall functionality are evident in daily use. One of the features I value most is the integrated AI system. It analyzes data intelligently and suggests logical diagnostic processes, which helps streamline decision‑making and saves time when troubleshooting. The D8S offers a wide variety of special functions, and the coverage within each brand and model is impressive. The module topology mapping is fantastic, providing a clear, color‑coded visual overview of the vehicle's health at a glance. Furthermore, the sub‑menus include numerous bidirectional tests, component functionality checks, and system‑specific procedures. This level of depth makes the tool extremely versatile for both routine diagnostics and more complex issues. Updates download quickly and without complications, and having three years of free updates is a significant advantage. Staying current with new models and expanded coverage is essential, and XTOOL makes this process simple and convenient. I also want to highlight the excellent support I received from the XTOOL team. Their communication was professional, timely, and genuinely helpful, which adds confidence when investing in a diagnostic tool. Although the D8S is clearly designed for professional technicians, it is also an excellent option for automotive enthusiasts who enjoy learning and understanding how systems operate. Its clear interface, extensive functions, and guided diagnostic features make it accessible even for users who are still developing their technical skills. As a practical suggestion, it would be beneficial to have the option to purchase a dedicated auxiliary cooling fan for prolonged use in hot environments, as well as an optional OBD2 main cable extension to improve flexibility when working around larger vehicles or components with limited access. Overall, the D8S has exceeded my expectations. It performs reliably, provides clear and extensive information, and offers a strong set of advanced functions. For anyone looking for a dependable, well‑supported, and feature‑rich scan tool — whether a professional or an enthusiast — the D8S is a great option. ... show more

  • My unit came with 2gb of ram, not 4gb of ram.
The D8S is advertised as having 4 gigabytes of RAM, I just booted up my brand new D8S and signed up for xtool account and started the update process. I checked the "memory" in the system settings menu and I am using "2GB" of ram of an available "1.97"GB" of available ram. So just to update the product over wifi Iam maxing out my ram, which is half of what it is supposed to be. Also, the D8S crashed in the first 5 minutes of updates and had to be restarted, costing me time. 4GB of ram is what I agreed to pay for. I received 2GB of ram on my model. This is half of what I agreed to pay for. I will contact Amazon for a full refund. This is false advertising. ... show more
