For advanced users, you can request or create an XSD schema from the Renolink developer (though not publicly documented). An XSD describes the exact rules for a valid XML file. If you have the XSD, you can validate using:
xmllint --schema renolink_schema.xsd yourfile.xml --noout
Without the official XSD, your best bet is to use a known working XML as a template and never deviate from its tag hierarchy. renolink valid xml file
To ensure an XML file is valid for Renolink: For advanced users, you can request or create
| Check | Action |
|-------|--------|
| XML syntax | Validate with any XML validator (xmllint, online tools) |
| Encoding | UTF-8, no BOM |
| Root element | <renolink> or <ecu> (case-sensitive) |
| CAN IDs | Hex format with 0x prefix, within 0x700-0x7FF for 11-bit |
| No trailing commas/spaces in hex values | 0x7E0 not 0x7E0 |
| Referenced diag files exist | The diag_file attribute must point to an existing file in the same folder |
| No CDATA misuse | CDATA is allowed but rarely needed; avoid inside numeric fields |
| Closing tags | Every <request> needs </request> |
| No comments inside tags | <ecu <!-- comment -->> is invalid | Without the official XSD, your best bet is
Every opening tag must have a closing tag or be self-closing (<param value="123"/>). Unclosed tags are the #1 cause of validation failure.
The specific requirements for a RenoLink XML file can depend on the version of RenoLink you are using and the specific tuning or data you are trying to modify or load. However, here are general steps to create a basic XML file that might be compatible:
