Decoding the Engine: Why the "TECDOC Motornummer" is Your Most Powerful Search Tool
In the world of automotive spare parts, precision is everything. Ordering a part for a 2015 Volkswagen Golf might seem straightforward, but without knowing the specific engine code (Motorcode) and engine number (Motornummer), you could end up with the wrong water pump, an incompatible timing belt, or a sensor that simply doesn’t fit.
- VAG Group (VW, Audi, Seat, Skoda): Usually on the engine block, above the oil pan, or on a sticker in the spare tire well or service book.
- BMW: Stamped on a flat pad near the oil filter housing.
- Mercedes-Benz: Often below cylinder 1 or on a label on the timing cover.
- General Rule: Check the vehicle registration document (Zulassungsbescheinigung Teil I in Germany, or V5C in the UK). The Motornummer is listed separately from the VIN.
Executive Summary
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. tecdoc motornummer
