1. BlueDriver Bluetooth Scanner – Best OBD2 Scanner for the money

BlueDriver Bluetooth Scanner 2If you want a professional diagnostic scanner, but do not want to spend thousands of dollars, the BlueDriver is a really great choice in my opinion. As you may understand from the price, it’s not really comparable with the other professional scanners, but do not judge it from the price!

The most cheaper scanners can only read the generic trouble code memory from the engine control unit, and if you are going to read the SRS, ABS and other control units, you have to check for a more expensive scanner. But not in this case. The BlueDriver can read the most different control units for the most known car models.

The reason for the low price for such a great scanner is probably because in this case, you will not get a large diagnostic unit. You will get an adaptor to connect in the OBD connector and you can then connect it to your phone via Bluetooth. This creates the opportunity that you do not have to pay for the whole unit.

Main Functions
  • Read & Clear Generic OBD2 Codes
  • Read Enhanced ABS, Airbag, Transmission codes
  • Compatible with a lot of car models
  • Freeze Frame Data
  • Live Data Analysis
  • Smog Test Check

The Bluedriver App which you can install on your phone is really easy to use and if you need support, you will get it. The support is open 24/7 which is really great. The database of repair information is also really great and if you are looking for a cheaper scanner that has the most functions as the other more expensive scanners, this should be your choice.

Pros
  • Easy to use
  • Great support
  • Large trouble code database
  • It can read enhanced trouble codes
  • User-friendly App
  • Covers a lot of car models
  • Small and easy to store
  • Low price
Cons
  • Does not have the advanced programming functions like the more expensive scanners.

OBD2 Scanners Buyer’s Guide

Choosing the right OBD2 scanner for your needs is not always that simple. There are hundreds of different scanners out there on the market to choose from. We wrote a small buyer’s guide of how to choose the right OBD scanner for your needs. We will go through things to consider before the purchase and some frequently asked questions about OBD2 scanners.

Things to consider when buying an OBD2 scanner

There are a lot of different things to look for when you are going to buy an OBD2 scanner. The process can be quite confusing but do not worry, You will find all the information you need here.

Compatibility

Different OBD2 scanners are compatible with different car models. The most Generic trouble code scanners can read the most vehicles after 1996 because they are using the same trouble code system. But if you want to read other control units like Airbag, ABS and transmission or others, you really need to make sure the scanner is compatible with your vehicle. You can often find this information if you go to the links to the products and you will find the vehicle coverage list at the bottom at Amazon. Make sure that you find your vehicle there. You can also double check this by sending a mail to the seller and ask if it’s compatible with your car.

Functions

You have to ask yourself, which functions you really need for the scanner. Are you going to do any codings or other basic settings, you may have to choose a more expensive OBD2 scanner. If you are only going to read the engine control module trouble codes and nothing more, then a cheaper generic trouble code scanner would fit you better. You can find the most functions of the scanners in the list above, but if you want to find the full list, I recommend you to go to the Amazon link and check the full description there.

Price

The price is an important part when you are checking for a scanner. How much are you going to use the scanner? If you are not using at much, you can probably choose a cheaper scanner as it will do the job for you. If you have a workshop and are reading several cars a day, you may want to choose a more durable and more professional scanner, which will probably cost a bit more. But, the price is not always telling you how the good scanner is. Some Cheap scanners can often surprise you and the more expensive ones can disappoint you. My recommendation is to check for scanners in our list, and you will most likely not be disa

Software Updates

Checking for how long you will get free updates of the scanner is important. Because what happens if you buy a new car and the scanner is not updated to that car model so you have to buy a new scanner to read it? There are coming hundreds of new car models every year, and the code scanner manufacturers do normally update the software in the scanner to make your scanner compatible with the new models also. Some scanner manufacturers do also have a limited time of free updates and it may cost you a bit to update it after that time. My recommendation is to choose a scanner with lifetime free updates.

Warranty

Always check the warranty time of the scanner before you purchase it. There can problems with the scanner directly from the manufactures, and you do really want to have the ability to send it back and get a new one. It’s also good to have if you do not like the product and want to send it back. You will find the warranty time at the manufacturer’s homepage or at Amazon if you enter the links to the product.

 

OBD2 Scanner FAQ

Why you should buy an OBD2 scanner?

There are a lot of reasons why you should buy an OBD2 scanner in my opinion. The most important is probably that you will save money in the long run. Visiting a mechanic is both a time consuming and money consuming problem. A mechanic does normally charge you 10-100$ to just read the trouble codes from your vehicle. Add all these mechanic visits and then count on how much a trouble code scanner costs. You will realize that you will probably earn that money back pretty fast. It’s really easy to read the trouble codes and if you need further help, you can bring the trouble codes to your mechanic and you may get some free recommendations of what parts to replace or how to fix the problem.

In my opinion, buying an OBD2 scanner is a really good investment that every car owner should do.

Why do I need an OBD2 scanner tool?

Modern cars are becoming more and more advanced and hard to troubleshoot. What is good with modern cars is that the control units are really smart, they are doing the troubleshooting for you. If there is not a parameter that is correct, it results in a trouble code. With a DTC tool, you can get that trouble code and find out where you should begin your troubleshooting. It can save you a lot of money from starting to troubleshoot at the wrong end.

Which OBD2 scanner should I choose?

It depends a lot on what car you have and what your needs are. If you only need a scanner that can read the generic DTC memory you can almost choose which OBD2 scanner you want. If you have to read other control units like transmission, abs and airbags, for example. If you want to search for other systems than the generic engine memory, you have to get a scanner that can search in those systems for your car model. Many car manufacturers have specific manufacturer trouble codes that you only can read with good OBD2 scanners.
If you want a scan tool that can search in several control units and read the manufacturer DTC codes, you have to read the specific descriptions of the scanners to find out if it’s compatible with your car model.

Can all of them read all control units?

No, as I wrote before. The most cheaper scanner tools can only read the generic trouble code memory. If you want to read other control units and manufacturer trouble codes, you have to consider buying a more expensive scanner which is compatible with your car model and engine.

Where is my OBD2 connector located?

Normally the OBD2 connector is located on the left side under the steering wheel ( If left-handed driven). Same side if it is right-hand driven. If you want to find your OBD connector location you can use this site to find it out: OBD2 Connector location

Which scanner is the best OBD2 scanner for the money?

All of these OBD2 scanners are good scanners for the money, but our favorite is the scanner if you are looking for a budget scanner, or the BlueDriver if you want more functions.

I got a trouble code, where can I find information about what it means?

The first letter in the code will tell us what kind of trouble code it is.

  • P = Powertrain(Engine, Transmission)
  • B = Body(AC/Airbag)
  • C = Chassis(ABS)
  • U = Network ( CAN-bus )

The next first digits are telling us if the trouble code is a generic or a manufacturer specific 1=Manufacturer and 0=Generic.
If you want to find out more what the trouble codes are telling us you can check out our DTC code list. You can also use our search function for recent questions about trouble codes.

What is CAN bus?

CAN-bus is the communication between all the control units and often the communication to the OBD2 scanner. It can also use other communication types like LIN-bus. A common fault is when one CAN-bus line gets an error, it kills the whole connection. That is why there is a common problem that you will not get any communication with several control units if one is broken.

Do I need any other tools to read the DTC memory?

Normally you do only need the DTC scanner tool. In some vehicles like older BMW’s, there could be other connectors than the standard one. In these cases, you need other adapters to read the DTC memory. I do also recommend to always use a car battery charger while you are reading the DTC memory because you should have the engine shut off and ignition ON. If you do not use a charger and the voltage gets low, you will get a lot of trouble codes and errors that will confuse you a lot. If you want to find a good car battery charger, check out our article: Battery chargers

I have a workshop and need a good OBD2 Tool, which one should I choose?

It all depends on your budget and what car you want to diagnose. In my opinion, it’s a good investment to invest in a good OBD2 scanner as it may save a lot of hours in troubleshooting costs. If you want a kinda cheap tool that works well for the most cars on the market, check out the Maxisys.

Can I damage my vehicle with an OBD2 scan tool?

Yes, you can. But as the most scanner tools on the market are very safe. If you choose one of the tools from this site and always connect a car battery charger while doing any work on your vehicle, you do not have to worry. The most common problem is using a tool and does adaptions with low voltage, which can damage control units if you are very unlucky.

How do I connect my OBD2 scanner?

The process is really simple.

  1. 1. Connect a car battery charger
  2. 2. Find the location of the OBD connector
  3. 3. Turn on the ignition ( Engine shut off )
  4. 4. Turn on the scanner & Read the codes

Can I save money with an OBD2 scanner tool?

Absolutely, you will save the money you spent very fast. A mechanic workshop takes a lot of money just to search the DTC memory for you. In many cases, you can do it yourself with a cheap DTC tool. Remember that the mechanics DTC tools are often a lot more expensive and can see faults that the cheaper tools can’t. But for small tasks, you can save a lot of money. I also see that very often people guess and just replace part after part of their car before they’ve checked the DTC memory. Always check the memory first and you could save a lot of money.

There are cheaper diagnostic scanners out there, should I buy a cheaper one?

The cheaper OBD2 scanners can often only read the engine control module and the generic trouble codes. This may not be enough for the most workshops and you should look for a bit more expensive and advanced diagnostic scanner. If you still want a cheaper diagnostic scanner you can check out our other review for cheaper scanners: OBD2 scanners. These scanners do often not have programming and basic settings functions like the diagnostic scanners in this review.

Do I have to buy any additional parts for these diagnostic scanners?

It depends on what functions you need. For some of these scanners, you can buy additional functions like TPMS programming and other programming and diagnostic functions. Check what functions you need for your diagnostic scanner and buy the equipment after that. As I said before, these scanners have the most required functions for small workshops and in many cases, you do not need the additional functions.

Does it cost to update these scanners?

These scanners come with free updates after purchase. Check the product description and manual to learn how to upgrade your scanner and make sure it has the latest software installed for the best scans and diagnostic functions. Some of these scanners have automatic scheduled updates, and you just have to use the WiFi to make it update automatically.

Is these prices a One-time fee, or do I have to pay monthly also?

These diagnostic scanners have a one-time fee and you do not have to pay monthly fees to keep them updated. Check the product description on the product for the right information about the updates. This is what makes these scanners good, several other professional diagnostic scanners have an expensive monthly fee to get them updated to the latest software after purchase.

I have a small workshop, and looking for an overall usage scanner, which should I choose?

If you have a really small workshop and not a lot of money to spend, I would choose the MaxiCom MK808 diagnostic scanner. It’s a very cheap diagnostic scanner for the most required functions for a small workshop and it can read the most car models. If you already have an established workshop and are looking for a more advanced one, I would choose the MaxiSys MS908P. The price of that scanner is 4 times higher than the MaxiCom, but you will also get a lot more required functions and it can scan and program more car models.
