Even experts trip up. Avoid these pitfalls:

If you cannot find the physical number, you can use the TecDoc online catalogue (or sites like partslink24, KP-Exerts, or aftermarket store finders) to identify it: tecdoc motornummer

Using the wrong engine code is the #1 reason for returns and restocking fees in the auto parts industry. Here is why the TecDoc Motornummer is your most powerful tool: A critical but often misunderstood component is the

The TecDoc catalog system, maintained by TecAlliance, is the global reference for vehicle spare parts identification. A critical but often misunderstood component is the engine number (Motornummer) . Unlike a Vehicle Identification Number (VIN), the engine number is not always standardized across manufacturers. This report clarifies how TecDoc processes engine numbers, links them to vehicle configurations, and enables accurate parts selection. Key findings: (1) The engine number is essential for distinguishing variants with the same engine type but different components; (2) TecDoc uses a proprietary engine code normalization to cross-reference OEM engine designations; (3) Correct usage prevents costly mis-ordering of timing kits, gaskets, injection systems, and engine management parts.
