The dreaded “Unable to find a .ROD file” error in VCDS can be frustrating. This guide explores a common scenario involving a missing ROD file for EV_MUHig6C3Gen2HBAS 001115 (VW37) and potential solutions.
While a previous VCDS version (17.3.1) claimed to resolve this issue, some users still encounter it, even with the 17.12.0 beta. The error specifically states: “Unable to find a .ROD file for: EV_MUHig6C3Gen2HBAS 001115 (VW37)”. Investigating the UDS_EV folder reveals similar filenames (EV_MUHig6C3Gen2HBAS), but none with the VW37 suffix. Available files include:
Available ROD files in the UDS_EV folder
Both the standard and beta installations exhibit the same file list. One potential solution found in a forum thread involved a successful scan using the AU37 version of the .ROD file. This raises the question: Can you simply copy the AU37 file and rename it to VW37?
While tempting, simply renaming the AU37 file to VW37 doesn’t resolve the issue. VCDS likely uses an internal naming scheme within the .ROD file itself, rendering a simple filename change ineffective. Further analysis of the auto-scan data between a successful case and the problematic one reveals a difference in component identifiers. The working component was MU-H-ND-EU, while the problematic one is MU-H-LND-EU. This slight difference in component identifiers might explain why the AU37 fix doesn’t apply and why VCDS can’t locate the correct .ROD file.
This discrepancy highlights the importance of matching the precise component identifier when troubleshooting missing .ROD files in VCDS. While renaming might seem like a quick fix, understanding the underlying component differences is crucial for a successful resolution. Further investigation into specific component variations and corresponding .ROD files is necessary to address this “Vcds Rod File Missing” error.
