As an automotive repair professional and a long-time user of VCDS (VAG-COM Diagnostic System) from Ross-Tech, I recently decided to explore a new OBD2 Bluetooth diagnostic tool that promised similar capabilities but with the convenience of wireless connectivity. Excited to test its potential as a more portable solution for quick diagnostics and basic settings, I purchased one and immediately put it to work on a range of Volkswagen and Audi vehicles.
My initial experience with this Vcds Obd2 Bluetooth tool has been largely positive, mirroring the claims of accessibility to control modules, adaptations, coding, fault reading, and live data – functionalities that seasoned VCDS users are well familiar with. In these aspects, the tool performs admirably, offering a user interface that’s quite intuitive for anyone accustomed to the comprehensive diagnostic environment provided by VCDS.
However, during my testing, I encountered a notable issue specifically related to performing basic settings on older Volkswagen and Audi models equipped with VE rotary pump diesel engines. This communication timing problem seems to manifest when attempting to execute basic settings procedures on cars with engines like the AHU and ALH. Interestingly, this issue doesn’t appear to affect newer PD (Pumpe Düse) diesel engines, suggesting a peculiarity in the tool’s communication protocol with the older VE rotary pump ECUs.

The primary symptom of this communication timing issue is observed when trying to check injection pump base timing. Due to the erratic communication, accurately verifying and adjusting the injection pump timing becomes unreliable. During the basic setting procedure, the glow plug light flash rate behaves erratically, and the injection pump timing readings in field 2 fluctuate wildly, making it impossible to obtain a stable and dependable measurement. This is in stark contrast to the consistent and reliable performance I’m accustomed to when using Ross-Tech VCDS for the same tasks.
I promptly reported this feedback to the developers of the OBD2 Bluetooth tool, and to their credit, they have been remarkably responsive. This level of engagement is encouraging, indicating a commitment to product improvement and user satisfaction. In fact, just recently, I received a software update, which suggests they are actively working to address reported issues like the communication timing problem I encountered. I am yet to thoroughly test if this update has resolved the basic settings issue on VE rotary pump cars, but the quick turnaround time on the update is a positive sign.
It’s important to note that this OBD2 Bluetooth tool is still under active development. Like any evolving product, especially in the complex field of automotive diagnostics, teething problems are to be expected. The key is how responsive the developers are to user feedback and their dedication to resolving these issues. My experience so far indicates a proactive approach from their side, similar to the responsiveness and continuous improvement ethos that Ross-Tech is known for with VCDS. I have personally provided feedback and suggestions to Ross-Tech over the years and have seen them incorporated into VCDS, so I appreciate this collaborative approach to product development.
Looking ahead, I will be rigorously testing the latest software update to ascertain if the basic settings issue on VE rotary pump engines has been resolved. VCDS remains my trusted benchmark for comparison, given my extensive experience with it since 2006. Currently, VCDS maintains an edge in user convenience, possessing more comprehensive label files and integrated hints and tips that streamline diagnostic procedures.
The developers of this OBD2 Bluetooth tool are also diligently working on a long coding helper, aiming to replicate a feature similar to VCDS’s Long Coding Assistant for Mk5 and newer vehicles. While still a work in progress, this feature holds considerable promise and could significantly enhance the tool’s capabilities for more in-depth coding and adaptations on newer VW/Audi models.
In conclusion, this VCDS OBD2 Bluetooth tool shows significant potential as a viable wireless diagnostic solution for VW/Audi vehicles. It effectively mirrors many core functionalities of VCDS, offering access to crucial diagnostic and service functions. While the communication timing issue with basic settings on VE rotary pump diesel engines is a current limitation, the developer’s responsiveness and ongoing updates suggest that this, and other minor shortcomings, will likely be addressed in future iterations. For now, VCDS remains the more polished and feature-rich option, but this Bluetooth tool is definitely one to watch as it continues to evolve.
