We are going to detail in today's topic some of the most used scanners. Obviously, this topic is dedicated to people who are not clear about what readers need and what they need.
I hope that when you finish reading this topic, it is clearer which the best OBD2 scanners are!
On this page you will notice that we do not sell any obd2 product or software, therefore we will always try to see this world from the impartial point of view, trying to transmit as much clarity as possible.
The choice of the buyer is the determining factor when purchasing a scanner.
The first thing we must take into account is the age of our vehicle and therefore know if our vehicle is OBD or OBD2
Once this detail is solved it is necessary to see what use we are going to give to our future code reader.
If we are merely amateurs and only want to get information from the switchboard and erase the errors of this I recommend a generic reader by usb cable or by Bluetooth. Its price is quite low compared to others since they are low cost readers.
A generic or multi-brand reader can cost thousands of euros. Everything depends on the capacity and quality of the reader.
There are also diagnostic readers whose connection to the computer is RS232 is an important detail considering that most new laptops do not have an RS232 connection. In addition, the RS232 connection tends to disappear.
When to buy a scanner by Bluetooth and when by USB?
The answer is simple knowing what our means are.
If we do not have a laptop and if we have an Android phone, it is obvious that a Bluetooth scanner is recommended.
If it is the opposite, we should buy one by USB to connect it to the laptop and get all the information.
If we do not have any laptop or phone we can buy an obd2 scanner with integrated screen that gives us the information without the need of another device. These are usually more expensive.
When we want to delve more deeply into the subject of our vehicle and be able to modify some data, we must then acquire a specific scanner for the brand of our vehicle. This can only be used in our specific brand (some in several brands).
This exclusive scanner for the brand of the car will offer us many more data, in addition to seeing failures that the switchboard register and not notice to the driver. Detail that the generic does not perform.
That is why it is important to know what scan to buy for each brand!
Some of these scanners have a very affordable price (40 or 50 euros) and are specific to the car model we have. This is the case of VAGCOM with a very low price compared to other brands in addition to being used in the VAG group (skoda, audi, volkswagen, seat).
In other cases it is difficult to lose 300 euros for a specific scanner of a brand.
Our obd2 cable does not help if we do not have the right program for it.
Always look for trusted websites and get the specific program for our machine.
