Introduction To Audi/VW Scanners
A VW/Audi scanner is an OBD tool that is compatible with Volkswagen and Audi vehicles. For those who need to know, an OBD scanner is a device used to diagnose on-board systems of a car.
The most basic scanners display diagnostic trouble codes (DTCs) that are stored whenever the car detects a problem anywhere in its systems. The problem may have occurred in the powertrain, chassis, body or anywhere else in the car.
Regardless, if you have a VW or Audi scanner you may be able to view the codes and in some cases read live, freeze frame data, etc. Ultimately, all these pieces of information will help you identify the problem, and even fix it (if you know how to).
Now, with that in mind, which is the best scanner for Audi and VW car owners? Sit back and relax as we take you through this review of our top 7 picks. Here’s a comparison chart to get the ball rolling.
Best VW Audi Scanner Reviews
1 Carista OBD2 Bluetooth Audi VW Scan Tool

Carista is an Audi and VW scanner that pairs with iOS and Android smartphones to perform diagnostics. It’s an adapter. What you do is install an OBD2 app (like the Carista App) on your phone and then connect the phone with the Carista adapter via Bluetooth, which turns the adapter into an OBD2 interface that links your phone with the car’s ECU. And you will be able to perform a wide range of diagnostic functions.
One of the things that you can do is read and clear codes. On VW and Audi cars, Carista supports viewing and erasing engine, ABS, airbag and transmission codes. It follows that this VW and Audi diagnostic tool can reset the Check Engine Light as well as ABS and airbag warning lights.
Besides that, Carista has some dealer-specific functions for VW and Audi. They include service light reset, EPB retraction and viewing of ECU information.
Like most other OBD2 adapters, Carista does an excellent job in relaying real-time data. You can view parameters like engine temp, calculated engine load, fuel trim, vehicle speed, MAF air flow rate, torque, fuel economy, etc. Just keep in mind that the exact number of gauges that you will see depends on the app you use.
The Carista adapter works with the Carista app as well as third-party apps like OBD Fusion, OBD Auto Doctor, OBD Car Doctor, and Torque Pro. So be sure to choose an app that offers as many functions as possible; like OBD Fusion.
All in all, Carista earns a spot as the best VW Scan tool (or the best Audi scan tool for that matter) because of its simplicity. Connecting it with a smartphone takes a few easy steps.
Despite that, it allows you to diagnose all the primary systems (engine, ABS & airbag), to view the live data and to monitor fuel economy to name a few. That’s why it’s one of the best apps for car owners with OBD2-compliant vehicles.

Carista allows you to diagnose all the primary systems (engine, ABS & airbag).

Pros
- Has special functions for Audi and VW cars
- Small, compact and lightweight. Can be left plugged in the car’s OBD2 port
- Comes with the premium version of Carista app for free for one month
- Compatible with third-party apps

2OBDeleven Pro Bluetooth Full System VW Audi Scanner with Programming and Monitoring

If you like the idea of an OBD2 adapter but don’t want to use Carista you may consider the OBDeleven Pro. Just like Carista, the latter is a dongle that plugs to the OBD2 port of your VW or Audi car. It then pairs with your mobile device (smartphone or tablet) via Bluetooth and allows you to run diagnostics from that mobile device.
Although they are similar in many ways, Carista and OBDeleven Pro also differ significantly. For starters, OBDeleven works on Android devices only. That means VW and Audi car owners who use iOS devices exclusively can’t use this adapter.
Besides, OBDeleven Pro is only compatible with the OBDeleven App. That limits the number of OBD2 apps that you can use to just one. Again, if you are a VW or Audi car owner who prefers a different app (like OBD Fusion, Torque Pro or any other), then you are out of luck.
In terms of functionality, OBDeleven is just as good, if not better than Carista. For one it can identify your car make and model automatically using the VIN. Besides, this Audi and VW diagnostic tool can read and clear trouble codes from all major systems. That includes the engine, ABS, airbag, and transmission.
So if you are looking for the best VW scan tool or the best Audi scan tool for resetting the MIL and other warning lights, OBDeleven Pro should make the best choice.
The one thing that gives the OBDeleven scanner an edge over other adapters is its wide range of advanced functions. With it, you can reset oil service, relearn brake pads after replacement, adjust car lights, view live sensor data, view freeze frame data, perform coding, make adaptations, and so much more.
In short, if you own a VW or Audi car, the OBDeleven Pro might prove to be invaluable. It is especially great for enthusiasts and DIYers who frequently work on VAG cars. The tool is compatible with OBD2-compliant vehicles.
