Are you experiencing frustration with your Veepeak OBD2 scanner failing to connect to your vehicle? Specifically, users of the Veepeak VP11Plus model have reported connection issues, particularly with certain car brands. If you’re encountering this problem, you’re not alone, and understanding the potential reasons can help you troubleshoot effectively.
The issue doesn’t appear to be a general problem with OBD Fusion, the popular app often used with these scanners, but rather seems specific to the Veepeak VP11Plus interface itself. Initial investigations suggest that the root cause lies in protocol compatibility. Many vehicles, especially European models from manufacturers like Audi, VW, and BMW of the E46 era, rely on the ISO9141 and KWP2000 protocols for OBD2 communication.
It’s suspected that the Veepeak VP11Plus may not fully support these protocols, or there might be a firmware or hardware bug hindering proper communication. In contrast, American car brands like Ford and GM often utilize J1850 and CANbus protocols, depending on the model year. This protocol discrepancy could explain why VP11Plus users are facing connectivity problems primarily with European vehicles. While other Veepeak OBD2 interfaces are known for their reliability and broader compatibility, the VP11Plus seems to present limitations, especially for older European cars using ISO9141.

It remains unclear whether this issue stems from a production defect in certain batches, a firmware flaw, or a deliberate limitation in protocol support within the VP11Plus design. The VP11Plus is a newer addition to the Veepeak product line, and this incompatibility is disappointing, especially for users seeking a cost-effective, low-power interface for continuous vehicle monitoring. For now, it appears the Veepeak VP11Plus might not be the ideal choice for owners of European vehicles requiring ISO9141 or KWP2000 protocols.
Further investigation and communication with Veepeak are needed to clarify the exact cause of this connectivity issue and potential solutions. If you are experiencing “Veepeak Obd2 Not Connecting” with your VP11Plus, especially with a European car, protocol incompatibility is a strong possibility to consider. Before purchasing, always verify the compatibility of any OBD2 scanner with your specific vehicle’s make, model, and year to avoid such connection frustrations.
