BlueDriver Bluetooth Pro OBDII Scan Tool for iPhone & Android - No Subscription Fee - OBD2 Car Scanner and Code Reader - Diagnose Check Engine, ABS, SRS, Airbag & 7000+ Issues on Vehicles 1996+

Been using mine for 3 years and it has been great. I leave it always plugged into my truck so that it is ready to use if I get a check engine light or even if I'm just curious about how the engine is running. It is well worth having, as it has saved more than its cost in not having to pay for diag time at the shop for minor problems that are easily fixed with an off-the-shelf part or when dropping off for things like the inevitable emissions sensor that goes bad. Being able to tell them "It's theowing this specific permanent code and it started on this date," before even taking it in saves paying for that time amd has saved time, as well, as they'll usually order the parts right then, so they can get it done a day sooner when dropping it off. 👌 For any code you get, it tells you what it is, likely fixes for it, and even shows a chart of how many people reported each potential fix as being what resolved the same code for them, PLUS usually a link to buy the part on Amazon if you want to. Also handy for clearing unimportant temporary codes that still throw a MCL/check engine light, since that's one of the only caution lights vehicles have these days, as well. Aside from problems, it can show you real-time data from the vehicle's computer for every sensor it has, which is pretty nifty even if you aren't using it to tune the engine or anything like that. You can gain insights into why maybe the engine feels rough or why it's not accelerating like you normally expect, for instance, by seeing timing information, engine load values, actual throttle position, fuel flow rate/pressure, more temperatures than you ever thought necessary, and more depending on the vehicle. And using it is a cinch. Just plug it into the ODBII port, fire up the app, and it'll find the sensor. Then, pick whether you want to see live data, scan for problem codes, add maintenance info, etc. It'll even show you codes that *don't* cause a warning light, which can help you get ahead of things before they become expensive problems. And it saves it all in history on your phone that you can export to excel or share with the shop or whoever you want. And it isnt tied to a vehicle, so you can just pop it into any vehicle, tap scan codes, and be done with it when your buddy complains their car is showing a check engine light. Overall a great product and does exactly what it claims. Couldn't be simpler to use, and has had zero compatibility issues with any Android phone I've ever used with it.

Easy to use and very informative. Setting it up isn't very tricky and the app can guide the user well. I used it to see and clear error codes many times, even kept it plugged in to monitor the O2 intake. Does the job well and definitely recommended

I used this on a 2008 Dodge Ram with the 6.7 Diesel and it worked like a charm, and I plugged it into a 2024 KIA K5 to see if it worked there as well and it does. Very easy to use, easy to read, reads and reports any issues fairly quickly, clears the codes I needed to, and at a very good price.

This review is written by the husband of the account holder. She bought this for me as a tool to help diagnose a issue with our vehicle. So the following are his words and not necessarily shared by the account holder. My (Hubby's) thoughts on Amazon: "They are liars and I will never order from them again! They have done nothing but screw up the shipping of this product from blaming Lemur to just plain outright telling a lie! Yes they did refund shipping and compensated my wife for this crap but it will be a COLD DAY IN HELL WHEN I WILL PURCHASE FROM AMAZON AGAIN!" The shipping and lying fiasco is partially why the rating is low. Some of the rating comes from the product itself. So let me get the issues out of the way first and then I will get to the good things. Which there are more good than bad I promise! Oh and another disclaimer: Use this tool as a diagnositc aid only!! This tool and others like it help point you in the direction of a fix and does not explicitly tell you what is wrong. So please use this tool to help get you pointed in the right direction. Just don't replace parts, use the tool to get direction, diagnose and then fix. Now to the issues I personally had with this tool: The live data PIDS take several restarts of the application to get to come online. I'm not sure if this is because of a special issue with my vehicle or what the issue is. This is annoying but can be overseen. I personally am a impatient person and like stuff to work the first time around. The second issue is issues that I have with a feature of the tool called Mode 6. My vehicle supports this and I was excited to see what all I can see however this is where the issues arise. The first issue is the app on the phone locks up sometimes when trying to go into mode 6. This isn't cool at all. A restart of the app fixes this as well. However once I get into mode 6, I get PID/TID readouts that are not human readable! I get TID/PID numbers and the output is in HEXIDECIMAL readout. The HEX part I know from working with computers however without a TID/PID chart, the data is WORTHLESS! In Lemur's instructional video on mode 6, they show you tapping on a TID/PID and it tells you what it does. On my vehicle, it gives some generic message which again is worthless. So mode 6 on this tool is completely worthless to me! A issue that seemed to correct itself through use is the repair reports. At first, I could not get the repair reports for the error codes on my vehicle then yesterday 12/29/15 I tried again and I was able to get the reports! Coolness! Now onto the good points! The tool will work with both Apple and Android mobile devices. I only was able to test on an iPhone so I cannot say how good or bad the Android device app is. The app and tool are updateable! As Lemur finds thing that need to be patched, they allow the app and the tool to be updated which is very nice indeed! The tood depending on what capabilities it knows about and what the computer allows, can not only scan engine codes but codes from other systems as well! Including ABS, Transmission and more! I ran into a snag on reading TPMS when I tested this tool on another vehicle. Lemur was notified and they are looking into a cause of why it couldn't read the codes from the TPMS systems of that vehicle. Might be that the computer didn't allow the tool access? Not sure. The tool once it finds issues will reveal the codes that are being reported. Then you can get a repair report. These diagnostic aids tell you what the code is and what are the most likely culprits that are causing it. Again use this as a diagnostic aid and not gospel for finding out the issue. This I feel is a nice feature! The tool can clear out the trouble codes. However I do wish that Lemur would tell you what state the car needs to be in to clear the codes. Like my vehicle has to be in the run position but engine off in order to clear the codes. Some cars need to be running. I think a safe bet here is key to run but engine off. The tool can check for smog rediness which for emissions is a definite must! If your vehicle supports it, the tool can check the status of the check engine light for parameters such as how long the light has been on and when the last time the light was reset. Again only if your computer supports it. The tool can decode a VIN and tell you where the car was made, what engine is in it, and all sorts of goodies. The tool makes an effort to figure out the VIN from the computer. However if it cant, then you can either manually enter it with a keyboard or if your car has a VIN barcode, you can take a picture of the VIN right in the app and it will fill in that blank for you! That is awesome! The live data tool is very good tool indeed! Depending on what you engine will allow to be read, you can see in real time what the engine is doing and help you narrow down what might be wrong! Best of all, a lot of the data from this tool like the Live Data, smog rediness, repair reports, etc can be exported out of the tool so if you need to analyze them on a computer or send to a friend that is more mechanically inclined, you can do so. A word of warning about the Live Data, it will only export out the PIDS you've selected and it only exports out data in a CSV (Comma Seperated Values) format useful in spreadsheets. It does not export out the pretty graphs ( I haven't found a way to export the graphs at least) that the tool generates. Would I personally consider this a professional tool? Possibly. Reasoning for my thinking is the mode 6 data/testing is useless to me as of this review. I noticed that some of the sensor PIDS are not even in the tool to be read or read in a certain way and should be if this is to be considered a professional tool. Case in point is the Cam and Crank sensors. Maybe this in in the mode 6 data however I do not know because again I can't read it and I cannot gain access to a TID/PID chart for this. Reason why reading the cam and crank sensors would be good is for a crank but no start condition. Even if we had a PID that would tell us that the cam and crank was in sync would help here. Without reading this data, this tool cannot help you with a crank but no start. At least on my vehicle which happens to be a 02 Jeep Liberty. However if you need a fairly inexpensive tool that is compact, fairly easy to use, updateable, IMHO very good support and can be used a a way to constantly monitor the vehicle (you can leave plugged in), this tool can definitly help with your vehicular woes. Maybe when the tool gets more updates, I will come back and update this review. If y'all are wondering if this has helped me with our vehicle? The answer is yes! I was able to get some live data and it is pointing to a few things that could be wrong with the vehicle. Once I get a clear day, I will get to cracking on this! Hope this helps someone.

I bought this BlueDriver Pro OBD2 Scanner Diagnostic tool, specifically to monitor the readiness monitors on my 2012 Shelby GT500, and it exceeded every expectation. I used it during the recommended drive cycle, starting from a true cold start, waiting for coolant temp to reach 170°, doing a few minutes of stop‑and‑go driving, then holding a steady 50–60 mph on the freeway. What impressed me most was being able to watch the readiness monitors (catalyst, oxygen sensor, and oxygen sensor heater) flip from yellow to green in real time right on my phone. Seeing those monitors turn READY instantly gave me the confidence to head straight to the smog shop, and I passed without any issues. That alone made this tool worth every penny. Beyond smog checks, this scanner is now part of my regular toolkit for all my vehicles. It reads codes, shows live data, and makes diagnostics simple and fast. Highly recommended for anyone who wants a reliable, accurate, and easy‑to‑use OBD2 scanner, especially if you’re preparing for a smog check.

Update: reached out to support and they were able to help me pair my iPhone. Unsure why it wouldn’t pair with the app guidance at first. They responded fairly quick and with detailed instructions. Highly recommend the product based on ease of use and support. Initial review: I have very mixed feelings about this product. First I will address my frustrations. I received the product, downloaded the app on my iPhone 17 pro max with latest OS and attempted to pair the device with the app as instructed. I spent a good 20 minutes troubleshooting bluetooth connectivity. Unpaired all bluetooth devices around me to include the radio. Still would not pair. Checked paired bluetooth devices that were paired and it showed the device however, the app still would not recognize it was paired. I pulled my android tablet, Lenovo yoga tab plus, to see if it was just a iPhone problem. Went through the steps and the app would still say it's not paired. Manually went into bluetooth connectivity and the device would just say it refused to pair with the tablet. At this point I was ready to return the product. I pulled an older android phone, about 6 years old, and downloaded the app. Ran it and paired effortlessly. Scanned my truck, cleared the codes, and all my issues were gone... I'll have to troubleshoot why my newer devices wouldn't pair but... I have been troubleshooting my 07 dodge ram 1500 SLT with 5.7 hemi for electrical problems or potentially having the TIPM repaired/ replaced (fairly expensive). I had cleaned and replaced the grounds. I also changed all the bulbs back to stock from the LEDs the owner prior had. Cleaned a lot of contacts. Checked voltages and wiring everywhere. Removed unnecessary wiring the previous owner had through out the truck. I was frustrated with the truck because you can't simply replace fuses and everything online just points to the TIPM. The headlight issues, turn signal, brake lights etc I was having, gone. Everything worked. I may reach out to support to solve my phone compatibility issues but I'm 100% satisfied with the results and hopefully others with TIPM issues will give it a try.

This was a great tool for more than 2 years, and I probably got my money's worth. But I own at least a TON of tools, and that's how good tools are supposed to work, you pay the price, it solves a problem, and you keep the tool, to solve the next problem. The COMPANY that makes BlueDriver, Lemur Monitors, is unethical and has no concern for their customers. They're cashing in by selling our data and are unconcerned about privacy, security, or their own reputation. AFAIK, on April 25th of 2025, version 8.0 of the Android app was released, and the tool refuses to do ANYTHING at all unless you sacrifice your personal data. Well, it flashes a RED LED at my feet now but I preferred the softer steady blue LED that meant I could access a functional tool. I have contacted Bluedriver via phone and email, they are aware of the situation, and have no intention of making any effort to address this failure. In FACT, they simply double-down with more marketeering mumbo jumbo "improve security, enhance customer support, and enable features our users have requested". Nonsense! Your security Was none of my concern, now you insist on my data...to IMPROVE my security? Name one company that has not suffered a data breach? Support was amazing when it was never required, you have a great tool, and it worked consistently on every vehicle I tried. Until you ENHANCED customer support. Customer support understands my problem and can do nothing at all. So this was enhanced for whom? As for features requested by customers...you think we wanted you to brick the device? That was the feature we were lacking? Or was it the intrusion? Along with the deliberate display of unethical business practices, there's no shortage of irony from a company that had previously thrived in the right-to-repair space. The good news is there are plenty of OBD II tools right here on Amazon, and frankly, the phone Bluetooth trick isn't really that handy. I mean the codes are 5 digits, not very difficult to search, and the corded one I ordered was under $25. If that mfg. wants to improve my life by bricking their tool, they're gonna have to drive over here and find it in my -pile- workshop. So if you need a RED flashing light on your feet while you're driving, this may be poorly named, but BlueDriver can do that, and if you act now, it's under $100! If you need a tool that reliably scans and reads codes from your OBD II ports, choose ANY other product, these idiots have jumped the shark. ___ I should add this started in April of '25, I have messages from BlueDriver beginning May 9. I gave them every opportunity to make this right, or even make any effort whatsoever. They have made no concession of any kind, no offer of a solution, a workaround, or even an offer to purchase my device that they seem so proud of. It's exactly the same they're still selling, they have made no improvements since mine was purchased in December of 2022 for $69.95. Even now, they certainly have my contact info, and I'm committed to updating this review regardless. ___ Amazon is asking me to comment on specifics: -Readability...no, I don't think management at Bludriver has any readability. They are the reason STOP signs are octagonal and red. -Compatibility is something Bluedriver has decided isn't important. Much like my ex. We used to be compatible, now they are compatible with no one. -App compatibility is great if you have an Android phone, you're the sort of person that leaves the windows rolled down and the car running in drugstore parking lots, your ATM PIN is 0000 and you post pics of your kids online and always use their full name. Not sure about the iOS app, but if you can't trust Tim Cook. -Battery life is about 2 years. I mean, OBD II doesn't offer much beyond voltage, but the tool worked for 2 years, and now it will never work again. It is powered by the OBD II port, which is powered by the vehicle battery. Unfortunately, none of them will work right, even fresh out of the box. -Programming capability is not the fault of the clever folks doing the backend coding, they do good work. I'm sure they are smart enough to know capturing personal data is a disaster, a ticking time bomb. The imbeciles running BluDriver FAILED to exert any effort whatsoever contemplating their decision, and the programmers did as they were paid to do. -Fit, yup. It do. And it has this neat LED that flashes RED 24/7 until it unfit. I strongly suggest unfit. -Color is RED but then off, then RED, then off. When it falls between the seats it's either black or invisible. -Size is just right, the red light covers the floor at my feet, and in one car, makes my right knee all glowy and flashy. It would be a LOT easier to find if it we're the size of a chest freezer. I couldn't find it for a while, it fell between the passenger seat and the door sill.

I picked this up because I’ve been looking at used vehicles and wanted a way to check for issues before buying anything. I’ve used it on a few cars so far, and it’s honestly been really helpful. It’s super simple to use—just plug it in and connect to the app. From there, it walks you through everything and explains what the codes mean, which is great if you’re not a mechanic. What I like most is that it doesn’t just give you a code—it actually gives you details and possible fixes, and even videos in some cases. That makes a big difference when you’re trying to figure out how serious something is. For me, this takes a lot of the guesswork out of looking at used cars. Instead of just trusting what you’re told, you can check things yourself. Only thing to keep in mind is you do need to use the app, so make sure your phone is compatible and you have a connection when using it. Overall, if you’re shopping for a used vehicle or just want to keep an eye on your own car, this is a really useful tool to have. I hope this helps.

Works a treat! A great devise for DIY diagnosis and fix.

يعطيك انذارات ما تطلع بالقطع العادية ولا بشاشة السيارة وتطبيقهم يوضح لك القطعة الخربانة و الاسباب الممكنة

From what I understood this product was originally designed to diognose american cars. But after trying on my British brand car I was pleasantly surpised how well it works. It cleared my ABS warning light which shouldn't have been on in the first place and it never came back on. On top of that it tells you clearly whats wrong with the car as well as allow you to view live data

Facil de usar e instalar. Buena comunicación con teléfono móvil. Funciones limitadas pero esenciales para el diagnóstico general del auto.

Very well.
