LAUNCH CR619 OBD2 not only offers basic features such as CEL codes, EVAP/O2 test, and fuel system information but ABS and SRS code reading as well. In most cases, these handheld devices only read error codes and show them in plain text on their display. With some it is also possible to delete error codes from the vehicle’s fault memory. Additional functions are rare. It places full diagnostic control over your vehicle in the palm of your hand by using your smartphone’s interface to manage your Volkswagen or Audi’s functionality and operation. In addition to all these features, the Autel MST505 OBD2

For the wireless scanners, I connected to my Apple iPad Pro, Microsoft Surface or Samsung Galaxy S9+ phone via a Bluetooth or Wi-Fi connection. The handheld scanners only needed to be plugged into the OBD-II port, which provides power. All in all, TOPDON AD Pro is the perfect choice for Audi home mechanics for comprehensive diagnostics and maintenance. The Bosch OBD 1300 diagnostic scanner stands out by including cables to connect with pre-1996 Chrysler, Ford, GM and Toyota cars. It can get heavy once the 6-foot extension cable is attached, but the OBD 1300's small size hides its powerful range of abilities. It must be understood that not every stored error code is relevant, as incorrectly measured values can also trigger a code. Therefore, a basic distinction is made between static and sporadic errors, and typically, static (permanently-occurring) errors are important for your vehicle’s functionality. On the other hand, sporadic errors are automatically deleted if they no longer occur after a certain number of driving cycles. A driving cycle is counted as one instance of switching the ignition on and off again. Even if the fault memory is read before the deletion of these faults, the warning lamp that may have been active before is no longer lit up. Is It Worth Reading the Memory Yourself? Although the exact location of the OBD-II port can vary from vehicle to vehicle, the port is typically located around the footwell on the driver's side, beneath the steering wheel and above the pedals. Why Trust UsThis 30-gram dongle is also capable of more than it first appears, even if you have to pore over a few YouTube videos to figure out what the information means. It will clear most basic error codes, though it doesn’t have the capacity to configure SRS. But that’s understandable, since SRS stands for “supplemental restraint system” and relates to the airbags. Finally, it also comes with a 12-month no-quibble warranty. Coding is essentially the personalization of the vehicle. You adjust the settings according to your preferences. Set which lights should come on during emergency braking or adjust the brightness of the dashboard lights.

We plugged the readers into a selection of cars of different ages, including a 2008 Mazda 2 and 2014 Peugeot 208 with known faults that were generating a warning light. Wireless readers were connected via Bluetooth to an iPhone using the app suggested by the device’s instructions. Verdict OBDeleven is a more expensive choice for those who want to comprehensively customize their VW/Audi.Transmission codes: This SRS diagnostic tool can read live transmission data when you’re driving. You will be able to see fuel information, live sensor performance, and other such details.

This device from Foxwell is one of the latter, meaning that it will be useful for cars that aren’t Volkswagen as well. Let’s see what features and specs it has. I've run scans on both our Polos and sorted the engine fault light on my daughter's, it was a one-off out of range brake switch reading which has cleared OK and not returned. Also found and resolved an issue with one of the aircon motors/flaps. To me the code fault detail seemed quite impressive and explained the fault sufficiently to assist tracing the issue. Besides the low price, we love the user-friendly nature of the XTOOL. 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. This is perfect for the DIY VW enthusiast. Here’s how such a process (a query of diagnostic data) runs internally — all in a fraction of a second! This little tool is specialized for Audi/VW, so we are pretty sure it will work well on VAG vehicles.

Why would I ever need to locate an OBD2 port on my Volkswagen?

The fourth and fifth numbers denote the specific fault being detected. It can be any number between zero and 99. OBDLink MX+ is a reliable SRS scanner that supports almost all devices including Android, iOS, Windows, and Kindle Fire. EPB reset: Problems in the EPB system are serious as issues with the system can lead to accidents. You can use this scanner to diagnose the EPB system and solve issues. One issue that plagues many OBD2 scanners is that they can become obsolete as soon as the codes change. Thus, if you decide to buy a newer vehicle, you’ll have to get another scanner as well.
