The type of diagnostics that can be done range from engine related problems such as diesel ignition timing to coding a new electronic control unit ECU. The VCDS diagnostic system uses a more detailed manufacturer protocol commands and allows the user to access all the diagnostics that have been installed in the vehicle provided it is a Volkswagen or Audi. On of the key components to good vehicle maintenance, repair or upgrade is to make sure that you have the right tools and know how to use them.
Using the VAG-COM diagnostic tool will show you the state of your engine, how it is performing and then you can make the required adjustments to ensure that your car runs as economical as possible and reliably. It then codes them into 4 character codes which are simple to understand and each one is related to the performance of the vehicle.
There are thousands of different codes and by using the VCDS system it will direct you to exactly where the problem is lying. In short, if you have a Volkswagen or an Audi there you no longer the need to guess what is wrong with the car or doing modifications by trial and error.
The great thing about the VAG-COM diagnostic system a person no longer has to visit the dealer and pay an astronomical price for the service but you can do it right from your home. After the software has been downloaded onto your laptop… start the VCDS from the shortcut icon on your computer and the main screen will appear.
It will show all the options that are available. Then you select the port or USB that it is connected to. Press the test button and the test window will show. To test the vehicle you will need the cable that plugs into the car and the plug is in the vehicle cab normally placed somewhere in the dash of the car. Each chassis number have different control modules that exist across the VW and Audi range and with newer cars, there are more control modules and the reason why the chassis number is important is that not one of the cars have all the modules.
The newer models that have a full CAN diagnostic system a person can use the auto detect function of the software. The VAG-COM directory has a file for all the vehicle profiles and it can be edited if you press the hyperlink above the chassis type. If you are not sure of which controllers you have in your car you can use the control module finder.
Press the start and the auto scan will start. This process can take a while but after it is completed the lines that are printed in Red are where there are faults. You click on these and the fault codes can be cleared. Using fuel trim as an example the VAG-COM will check the current status of the fuel trim and in this case, you need to check the appropriate group for the vehicle.
Once you have accessed the code you will find two percentages. The first percentage is when the car is idling and the second percentage is when the car is operating at faster speeds. Negative figures indicate that the vehicle is running too rich and the oxygen sensor is, therefore, closing the injectors to soon.
Positive values are the engine is running too lean and the opposite effect will take place with the injector control. There will very seldom be zeros in both the fields and if there are you have probably cleared the values. One of the advantages of using the VAG-COM diagnostic system is that you have the flexibility to do readings of the various sensors in real time.
Firstly you need to choose the modules and generally, these modules are all listed under the engine option. By using the features you are able to log more than one group at a time. These can include the air mass meter diagnosis, vehicle speed but that is generally just for interest and coolant intake and temperature which is a good way to compare the revs against the vehicle speed.
Using Block there will be readings in column 3 and 4 which will be the requested boost and the actual boost. The ECU is programmed to control the turbo waste gate to achieve close to the requested boost. Therefore when the car is at full throttle then the deviation should at no time be higher than millibars. If the deviation is higher than that then there could be a problem.
Just like block you can measure the amount of torque and compare the readings to other parameters such as the boost and duty cycle.ODIS System provide flexible fault diagnosis, clear data test display, convenient diagnosis entrance.

Unfortunately for me, I got a chance to own the first generation VW Touareg. Let me tell you, the VW Touareg is an extremely capable SUV, but it had all sorts of problems, specifically issues with the check engine light. The problems were so bad, that I inherited the car along with all the problems that came with it.
*You are using an old version of Internet Explorer. Please upgrade it.
I decided to sell my SUV, but not before diagnosing the check engine lights. You see, it is quite difficult to diagnose a European car. Since German cars come with more CPUs to govern the engine, transmission, airbags, ABS or anti-lock brakes and other electronic accessories, you need an OBD2 scanner that is specifically made for a Volkswagen.
And VW is no exception. To see exactly what codes the Bluedriver will show on your Volkswagen, simply lookup your Year and Model on their website here: Bluedriver vehicle support. We tried this on our VW Jetta and it was able to diagnose a faulty camshaft sensor. For the price, the display is okay, but it is nothing to write home about. Besides, what matters is that the product works, and it is a stand-alone unit that can diagnose and turn-off the check engine light on your VW, without the need for additional gadgets or computers.
We simply plugged it in the diagnostic port of our Jetta and the device automatically turned on. It then proceeded to scan the entire system without pressing a ton of buttons.
It simply works. If you previously thought that wireless OBD2 scanners are expensive, then you better think again. This tool can also display current sensor data including intake manifold pressure, mass air flow, fuel level barometric pressure and air intake temperature.
It works via Wi-Fi, so it connects to your phone or tablet via wireless. You will have to install an app on your phone. It was able to reset the oil service light and retrieve the VIN number of the Golf. It is also compatible with Seat and Skoda vehicles sold worldwide beginning This device can read and erase diagnostic trouble codes of the engine, transmission, radio, climate control, steering, immobilizer and many more.
What we like the most about this VW obd2 scanner is that it comes with a rather large backlit LCD display, which is the kind that you would expect from more expensive OBD2 scanners. There you have it, the 5 best OBD2 scanners for Volkswagen vehicles. Do you have questions or comments? We would love to hear from you. You must be logged in to post a comment.
