Tecdoc Motornummer 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

Depending on the manufacturer and the TecDoc database entry, the Motornummer can appear as a numerical ID or an alpha-numeric code (often matching the manufacturer's own engine code).

Spare Parts Portals: Online retailers like Autodoc or eBay list this number under "Technical Data" or "Compatibility" for specific listings.

Workshop Software: Professional garages use TecDoc-connected software to identify the number via the vehicle's VIN or KBA number (Germany).

Manufacturer Label: The code often corresponds to the engine code stamped on the engine block or found on a sticker in the vehicle's service book. ⚠️ Why it matters tecdoc motornummer

Using the TecDoc Motornummer is critical because parts for the same car model can change based on the construction year or emission standard (e.g., Euro 3 vs Euro 4). For example, a 2008 VW Passat might require a different AC compressor than a 2011 model based on whether the engine code is BMR or CBBB.

To help you find the exact part or information you need, could you tell me: The make and model of the vehicle? Which specific part (e.g., alternator, belt, filter)

Do you have the VIN (Vehicle Identification Number) or Engine Code from your car's manual? AI responses may include mistakes. Learn more Valves and Components

Here is the detailed information regarding TECDoc and the "Motornummer" (Engine Number) , specifically how the leading automotive cataloging system (TECDoc by TecAlliance) handles engine identification. Kombination aus Buchstaben und Zahlen

This is crucial for workshops, parts dealers, and vehicle restorers to ensure they order the correct engine components.

Step-by-Step: Using Motornummer in a TecDoc Search

Let us simulate a real-world parts search using the TecDoc interface (or any retailer using TecDoc data, like Autodoc, Mister-Auto, or PartsPro).

Scenario: You need an oil filter for a 2008 Opel/Vauxhall Astra.

Step 1: Select "Vehicle Search." Step 2: Input the Manufacturer (Opel), Model (Astra H), and Year. Step 3: Instead of selecting "Engine" from a drop-down list, you type the Motornummer directly, e.g., Z16XER. Step 4: TecDoc instantly confirms: - Displacement: 1598 ccm - Power: 85 kW (115 HP) - Fuel: Petrol Step 5: Click "Parts List." TecDoc now displays only parts compatible with the Z16XER. A Z16YNG (different engine code) will see zero results for this filter. Beispiele typischer Bestandteile:

Why TECDOC Requires the Motornummer (Not just VIN)

Many parts sellers rely solely on the Vehicle Identification Number (VIN). While the VIN contains the engine code, it does not contain the sequential engine serial number (Motornummer). This leads to three common problems:

2. Aufbau und Varianten der Motornummer

Es gibt keinen weltweiten einheitlichen Standard für das Format der Motornummer; Hersteller nutzen eigene Systeme. Typische Merkmale:

• Kombination aus Buchstaben und Zahlen.
• Länge variiert meist zwischen 6 und 20 Zeichen.
• Einbettung von Informationen wie Motortyp, Hubraum, Leistungsstufe, Fertigungsjahr oder Produktionswerk.
• Manchmal existieren zusätzlich Seriennummern oder Teilenummern, die separat geführt werden.

Beispiele typischer Bestandteile:

• Herstellerkennzeichen (z. B. „VW“, „BMW“ intern codiert)
• Motorcode (z. B. „1.9 TDI PD“ als Kurzbezeichnung)
• Serien- oder Laufnummer (eindeutige Ziffernfolge)

Wichtig: Motornummer ≠ Motorkennbuchstabe (bei manchen Herstellern existiert ein separater, kurzen Code, der Motorfamilie und technische Basis beschreibt).

VW EA888 Gen 3 engines changed head bolt length and thread pitch mid-production. The engine number (e.g., CJSA vs CJSA with higher serial range) is the only reliable discriminator.
