Tecdoc Motornummer __link__ May 2026

The TecDoc Motornummer eliminates ambiguity when ordering parts. Since a single vehicle model (e.g., a VW Golf) can have multiple engine versions with different specifications, the engine number ensures you receive the correct part for: Performance parts (Injectors, Turbochargers) Climate control (AC Compressors) Engine internals (Crankshafts, Valves) 📋 Identification Examples

• Germany: Look at field K (Fahrzeug-Identifizierungsnummer) or sometimes specifically field P.3 (Kraftstoffart) combined with D.2. However, the specific engine code is often not printed directly on older documents. It is usually derived from the VIN.

• Reading the Wrong Number: The engine number is often confused with the engine type or code. If you type M54 (engine code) into the Motornummer field, TECDOC will return "No data found."
• Older Vehicles (Pre-1995): For classic cars, TECDOC data is sparse. The Motornummer search works best for vehicles manufactured after 1995 when digital records became standardized.
• Digit Misplacement: Engine numbers often include stars (*) or dots (.). In TECDOC, you usually omit non-alphanumeric characters unless the specific brand guide says otherwise.
• Regional Variations: A European Motornummer may be formatted differently from a US or Asian one. TECDOC software must have the correct regional database installed.

• Example (VAG - VW/Audi): AGR, AHU, AUX
• Example (BMW): M54B30, N42B20
• Example (Mercedes): M111, OM642

Furthermore, with the rise of electric vehicles (EVs), the concept of "Motornummer" is evolving to "EM-Nummer" (Electric Motor Number) . TECDOC already supports this for EVs like the VW ID. series, where the electric motor serial number determines the gearbox oil spec and bearing kit. tecdoc motornummer

Let’s say you have an engine code CDB (1.6 TDI) from a Volkswagen. You can enter just the Motornummer into TecDoc without the car model. The system will show you every vehicle that ever used that engine (Seat, Skoda, Audi, VW). This is invaluable for salvage yards or finding rare parts. Reading the Wrong Number: The engine number is

Common Mistakes When Searching by Motornummer

Even experts trip up. Avoid these pitfalls: Example (VAG - VW/Audi): AGR

Precision Fitment: Many parts (like timing belts, water pumps, and gaskets) are "up to engine number X" or "from engine number Y." Searching by engine number eliminates the guesswork common in generic year/make/model searches.
