The engine number is a unique alphanumeric code assigned by vehicle manufacturers to identify a specific engine's design, technical specifications, and production series. Within the TecDoc Catalogue—the world's leading vehicle and spare parts database—this "Motornummer" serves as a primary search criterion.

1. Sanitization – Remove spaces, hyphens, special characters. Convert letters to uppercase.
2. Prefix matching – Compare against known manufacturer prefixes (e.g., M52, F9Q, 272 for Mercedes).
3. Variant detection – Some engines share the same code but have different component specifications (e.g., oil cooler, injector type). The full number may indicate production plant or revision level – TecDoc uses this to filter parts.
4. Fallback – If no prefix match, the system may ask for additional attributes (kW, displacement, fuel type).
