Our Recommendations

It may seem hard to choose the best OBD2 scanner for your car, but it all comes down to your need. You should read the reviews carefully, keeping in mind what is it that you need from the scanner. We have ranked the best OBD2 scanners in general, focusing on all the options that they offer, as well as the price of the device. Considering all the features, we’ve come to the conclusion that we can recommend the following three devices as the best option for almost any user.

Number one on our list is the BlueDriver OBD2 scanner. The reason we chose it as number one is that it has great value. You get all of the options that you might need from a scanner, for a reasonable price. It is a Bluetooth device and it works with both Android and Apple devices. The user interface looks great and easy to use, once you choose the right app. We’re sure that this IBD2 scanner will offer you everything that you might need.

The second scanner on our list is Autel AL519 AutoLink. This reasonably priced OBD2 scanner provides more than just basic scans. It will retrieve almost all vehicle information and codes. You can use it to turn off the malfunction indicator lights and the device can read, record and playback live sensor data as well. It has a lot of options, but we must say that the build quality may have been a bit better.

Our third pick is a device that has an unbelievable price in our opinion. This was the main reason to rank the device this high on our list. It does have a limited number of options, but if those options are all you need, then this is the best OBD2 scanner for you. You can use it to read and clear the check engine light, monitor the O2 sensor, and check the temperature of every fluid in the car. It works with Android and Windows devices and comes with a two-year warranty.

Best and Worst Value

When it comes to the best value, our third pick, BAFX Products Bluetooth Diagnostic OBDII Reader, would be our recommendation. You can get this device for cheap, but it will offer many useful features. Even if you don’t get all that you wanted, you will still not be disappointed. At this price, we’re pretty sure your satisfaction is guaranteed. Plus, you have a warranty, so you can return it if it doesn’t meet your needs.

Our pick for worst value is not necessarily the worst value, but it is by far the most expensive OBD2 scanner on our list. The device in question is Innova 3160g Code Reader/Scan Tool. It may have a lot of useful options, but we think that you would be better off with a cheaper device once you pinpoint what exactly do you need from an OBD2 scanner. This device is for those that require almost fully professional vehicle scans. It will take some time for it to pay off, depending on how much you pay your local mechanic to perform a scan and how often you take your car to the garage.

Most Reviewed

All of the devices on our list seem to be very popular on Amazon. The one that leads the way with most reviews is the BAFX Products Bluetooth Diagnostic OBDII Reader / Scanner, sitting at 10 240 customer reviews. We do think that this is due to the fact that the device is really cheap for what you can get from it. One satisfied buyer says: “I know I had car issues but not to this extent. I was able to track down every issue (7) and figure out what it was gonna cost me. Literally saved me $700 from what the shop was gonna charge me to fix them. Makes me wonder if they were trying to rip me off”. By far the most popular OBD2 scanner we’ve reviewed.

In second place is our overall winner BlueDriver Bluetooth Professional OBDII Scan Tool. This just goes to show that the product is actually really good. At 2899 Amazon reviews, it holds a great second position when it comes to popularity. Considering the price, this can tell you a lot about the product. Happy customer reviews: “I should've written a review for this a long time ago. This thing saved me money. And I mean a lot of money. I recently bought a used car and this helped me weed out like 10 lemons. Ended up buying a car that was in much better shape for a really good deal.“ Quality and compatibility, as well as all the features, are what make this device so popular.

The third spot for popularity goes to ANCEL AD310 Classic Enhanced Universal OBD II Scanner, our fourth-placed scanner. This OBD2 scanner has 2282 reviews on Amazon, which makes it a popular option amongst car owners. The price certainly helped when it comes to its popularity, but the user interface and scan options pushed it forward as well. A satisfied buyer claims:” I have an older scan tool, that I paid $300 for back when I was a mechanic, that covers OBD1 just to tell you how old it is that doesn't do half of what this scanner does. No batteries are required and it easily reads the PIDs for diagnostics plus it immediately explains the codes that pop up. Great investment for a mechanic and do-it-yourself types.” Another great thing that helps this device gain popularity is certainly the fact that the manufacturer offers a three-year warranty on the device.

Highest Rating

The highest rated OBD2 scanner on the list is ANCEL AD310 Classic Enhanced Universal OBD II Scanner. Along with its third place in popularity, the high rating makes it stand out a bit more. It has an average rating of 4.6 out of five stars on Amazon. The crowd seems to love the scanner and the top positive review says: “It is very easy to use! I have never used an OBD scanner before and am a self-taught mechanic. I recently started working on my car after an incident with a mechanic trying to scam me. It successfully diagnosed the problem when my engine light has come on. It works as advertised and I have no complaints. I recommend it to anyone who owns a car as it can prevent a mechanic from ripping you off. Note that it tells you the problem but not the cause however it is very easy to find the cause. Simply Google the code number that pops up along with your car make, model, and year and you will find the likely answer to your car's issue.”

There are many similar reviews of the scanner and it has a rating of 78% five-star reviews.

Three Tips for Using an OBD2 Scanner

There are some simple things that you need to keep in mind when using the OBD2 scanner.

1. Before you purchase the OBD2 scanner, make sure that it will work with your car’s system. Some scanners have a limited number of vehicles that they can access. The good thing about this is that almost all of them will have a list of compatible vehicles listed in the product description.

2. Make sure that you don’t delete or remove the codes from the device before you’ve done the repairs. If you’re not going to do the repairs yourself, make sure that you’ve recorded all the fault codes before taking the car to the mechanics. Although most mechanics will do the scan themselves, you can then compare the results and make sure that they don’t charge you unnecessary costs.

3. If you’re going to do the repairs yourself, make sure that you understand what needs to be repaired. If your scanner doesn’t have a repair suggestion option, you should refer to the user manual to pinpoint the issue. Some error codes may show similar results and faults. This is why you have to check in detail what the actual fault code is.

When to Use the OBD2 Scanner

If you’re one of those people who like to do car maintenance themselves, you’ll certainly need to own an OBD2 scanner. If your car starts showing signs of malfunction or one of the warning lights comes on, this is when the OBD2 scanner comes into play. Instead of doing a visual inspection and wasting hours trying to pinpoint the issue, you can easily find the problem by simply connecting the scanner and performing a quick scan. If your scanner has a repair suggestion option, you will save yourself a lot of time. Instead of wasting your time on diagnostics, you can use that time to perform the repairs. Use the OBD2 scanner every time you feel something is wrong with the car. Even preventive scans are recommended because you can then plan the repairs in advance.


With so many people owning a car these days, the car maintenance industry is at its high. You can find repair shops and garages at almost every corner and they usually offer troubleshooting services for a certain price. With technological advancement, you no longer have to pay for these scans every time you feel that there’s something wrong with your car, or the check engine light comes on. You can purchase the scanning device and it will certainly save you money in the long run.

The great thing is that you can now use these devices with your smartphone. As you’ve already read, our top pick for the best OBD2 scanner, BlueDriver Bluetooth Professional OBDII Scan Tool for iPhone, iPad & Android, lets you do exactly that. You can simply perform all the checks on your vehicle by just plugging in the device and downloading the app. It saves you time, money, and in some cases health because you no longer have to stress about your car’s condition.

Make your life easier and get an OBD2 scanner for your car. It will be well worth it.
