Many cheap Chinese adapters do not support the ISO 15765-2 (CAN FD) or the specific timing required for WABCO bootloaders. Symptom: The download starts but freezes at 1% or 100%. Solution: Use a WABCO-approved device or a Nexiq USB-Link 2.

Final Pro Tip: Always keep a backup of the existing software parameters (Export → .wpp file) before starting any download. That way, even if the new software fails, you can revert to a known working configuration.
