XTOOL AD20 Pro OBD2 Scanner for Car 2025 Wireless Code Reader for iPhone & Android, All System Diagnostic Tool for Check Engine, ABS, SRS, Oil Reset, Voltage, Performance Test, No Subscription Fee

This review is for the Xtool AD20 Pro, a compact, wireless, dongle-style OBD2 scanner that transforms your smartphone into a full-featured diagnostic tool. At around $55, this is an exceptional entry-level scanner that punches well above its weight class in terms of features and functionality.I own several Xtool products, including the A30M (a more advanced wireless scanner priced around $160 with no subscription required) and the D7S, a professional-grade wired scanner that does require an annual subscription. The AD20 Pro sits at the entry point of their lineup, but don’t let that fool you, this tool delivers surprisingly advanced diagnostics for its price.The AD20 Pro supports a wide range of vehicles. I have successfully used it on a 2014 Jeep and a 2011 Suburban. When connected to a new vehicle, the app will prompt you to download the specific diagnostics for that make and model, simple and efficient.Once connected, it performs an All-System Scan, reading and clearing fault codes across systems including Engine, Powertrain, SRS, ABS, TPMS, and more. It easily handles diagnostics that most cheaper tools miss. Additionally, it includes valuable features like Oil Light Reset and Battery Check, which are frequently used maintenance functions.A good convenience is its built-in DTC Lookup, which pulls up definitions online for any fault codes, helpful for understanding and addressing issues quickly. Other features include: Live data streaming, Freeze frame data,ECU info, O2 sensor, component testing, engine load, RPM, fuel trims, MAF, misfire counters, voltage, and more.What you will not get at this level are the bi-directional controls and advanced reporting features (like saving and printing diagnostic histories), which are available on models like the A30M and D7S. But that is a fair trade-off considering the ease of use and price point.Bottom line: The Xtool AD20 Pro is a very good value for beginners or DIYers who want more than just basic code reading. It is a great starting point with plenty of features typically found only in more expensive models. Highly recommended for anyone looking for a reliable, feature-rich OBD2 scanner at an entry-level price.

XTOOL scanners will save you time and money! It is almost impossible live without one with all the electronics in today's cars. I now have the XTOOL D8BT, AD10, and the AD20 pro and love them all!Just yesterday while leaving work, my son's battery light came on in his Camry, so he took out the D8BT scanner from his trunk and quickly learned his alternator was not working. He had enough time to get to a parts store, repair the car, and return the core. Earlier in the day, I received my AD20 pro and decided to check it out on my 2007 Toyota Sienna Van. It worked flawlessly! It scanned my entire vehicle and cleared my TPS light in the dashboard.You must scan a QR code on the instruction sheet to get started. It will take you about 10 minutes to follow the easy to understand steps. Between each step is a little slow, I have a new 5G phone and the highest speed internet Spectrum offers. Once you plug the dongle in the OBDII port under the dash and your vehicle communicates with your phone via Bluetooth, you will see a big difference between the AD10 and the AD20 pro. I was hoping the AD10 app would work on the AD20 pro, but you will see that there are so much more parameters and sensors that are tested with the AD20 pro, that it needs a whole new app. When the AD20 pro tests your vehicle, it is very fast! What is new and amazing and where Wi-Fi comes into play is that the AD20 pro will not just give you the trouble code, it will take you to a website that explains the code and even recommend videos that you can watch on your phone to solve your problem. There is live data where you can select all or only the sensors you want to watch. Most times you will look at fuel trims, rpm, MAF, O2 Sensors, and voltage. So you can monitor what you prefer. You can leave the dongle in the OBDII port to monitor your driving habits. This scanner can tell you if you are driving well.Going back to my D8BT, my son self inherited it from day one! But I did not mind because I knew that he would make more use out of it than I would. Then XTOOLS gave me the AD10 which I keep in my truck at all times so that is the reason my son can keep the other scanner. As soon as I found out this AD20 pro scanner was available, I jumped on my computer to order one.The only times I have problems with my XTOOL scanners is deciding which one to buy. It wasn't long after the XTOOL D7 scanner came out that the XTOOL D8 scanner came available. It was hard enough deciding between the D7 and the D8 because now the XTOOL D8BT came out. I decided to buy the D8BT and that was the best decision I made. My friend bought the other brand that I was considering, I tried it and I would have been disappointed.Getting back to my XTOOL AD20 pro, again I had a little problem deciding between the AD20 or the AD20 pro. I chose this AD20 pro, but I am confident that either or would be a good choice!I know I went off track a little, but if you need a scanner to help you find out what is wrong with your car,you cannot go wrong buying the XTOOL AD20 pro scanner. I used to take my 1994 supercharged Previa Van to the dealership and pay $200.00 just for them to hook up a scanner to tell me the problem. If only I had my phone and the AD20 pro which both can fit in one pocket, I would have saved a lot of money.It is amazing how small the AD20 pro is. It is a small dongle that you plug into your OBDII port under your dash. I really do not have anything bad to say about this AD20 pro. I only have one suggestion to the XTOOL company, is that maybe they could make the dongle come in a bright color like yellow, orange, or lime green to help you locate it when you take it out of the box or OBDII port because being black, it blends in with the black consoles. If you are in the market for a scanner, you can not go wrong buying this XTOOL AD20 PRO!! With gasoline prices nowadays, you need this to keep your car in tiptop shape and even if you cannot fix or repair your own car or truck, you can prevent shops, mechanics, and others from ripping you off or trying to upsell you on things you do not need.This XTOOL company will go through great lengths to ensure your happiness and are quick to respond to your questions. They will let you know about any new products that they develop. It is such a good feeling to do business with such a great company that really and truly stand behind their products and who really and truly care about their customers!! Hard to find companies like this nowadays!
