10. Frequently Asked Questions (FAQs) About Audi OBDII Cable PC
Here are some frequently asked questions about using an Audi OBDII cable with a PC:
10.1 Will VCDS work with my car?
VCDS (VAG-COM Diagnostic System) works with most Volkswagen and Audi models sold worldwide from 1994 through the current model year. It may also work with some cars dating back to model year 1990. If your VW or Audi has a 16-pin “OBD-II style” Data Link Connector, VCDS will likely work. For older cars with a “2×2” Data Link Connection, ensure there is a wire going to each pin for diagnostics-capable modules.
10.2 Will VCDS work even if my car is “chipped”?
Yes, VCDS should work even if your car is “chipped.” Reputable chip vendors ensure that their chips do not interfere with diagnostic functions. If the factory scan tools can communicate with the ECU, VCDS should be able to as well.
10.3 What functions are included in the current release?
The current release of VCDS includes a comprehensive set of diagnostic functions, allowing users to perform the same diagnostic procedures as VW/Audi factory scan tools, following instructions in the factory repair manuals.
10.4 What are the computer requirements?
VCDS requires a computer running Microsoft Windows (the HEX-NET can be used with VCDS-Mobile on other platforms but that use is still in beta testing). A Laptop is most convenient but a desktop PC can also be used. We recommend a PC running Windows 7, 8.1, 10 or 11 with at least 2GB of RAM (single-core Atom-class processors are no longer recommended and Windows on ARM is only supported with the HEX-NET and HEX-V2). Screen resolution of at least 800×600 is recommended.
10.5 Should I get a Serial or a USB interface?
If you are using a modern PC running Windows XP or newer, a USB interface is recommended. USB interfaces are more future-proof as it becomes increasingly difficult to find new PCs with serial ports. For older PCs running older versions of Windows or with a CPU speed of less than 1GHz, a Serial interface may be more suitable.
10.6 What if the PC I wish to use with VCDS doesn’t have Internet access?
You can download the software from our download page on a computer with Internet access and transfer the file to the PC you will be using with VCDS via a removable USB drive or CD-R/CD-RW.
10.7 Can I use VCDS on a desktop computer?
Yes, you can use VCDS on a desktop computer. However, you may need an extension cable for your interface if the PC is more than 6 feet from the car’s diagnostic port.
10.8 Will there be a Mac or Linux version?
There will be no “native” Mac or Linux versions of VCDS. However, VCDS works fine on Apple Mac computers that have Intel processors when Windows is installed on them using Boot Camp. Alternatively, you can use the platform-independent version of VCDS called “VCDS-Mobile”.
10.9 What’s the difference between VCDS and an OBD-II Scan-Tool?
OBD-II is a government-mandated diagnostic protocol primarily aimed at diagnosing emissions-related problems. VCDS uses VW’s proprietary diagnostic protocol and is specifically designed and supported for use in VW/Audi vehicles. VCDS can access numerous “intelligent” systems in the car, while an OBD-II Scan-Tool is limited to the engine.
10.10 Can I use VCDS to roll back my electronic odometer?
No, VCDS cannot be used to change odometer readings, with one exception: the odometer reading on a brand new instrument cluster (with less than 100 km / 62 miles on it) can be increased, one time only.
