Sometimes, the Motornummer isn't enough. TecDoc may ask for a "Construction Interval" or "Engine Variant." For example, engine M57D30 (BMW) exists with 170kw and 210kw. Look for a 4th or 5th digit in the code (e.g., M57D30TU for Technical Update).
Let’s walk a real-world scenario.
Situation: A customer arrives with a 2008 Audi A4. They know the car is a 2.0 TDI, but they don’t know if it’s a BKD, BRE, or BMM engine code. You find the Motornummer stamped on the engine: 1234567.
Workflow in TECDOC:
Result: The customer returns 6 months later, no timing failure. Precision saved the day.

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. Sometimes, the Motornummer isn't enough
How does TECDOC stack up against OEM systems?
| System | Strengths | Weakness | | :--- | :--- | :--- | | TECDOC | Cross-brand; shows aftermarket alternatives; Motornummer search standard. | Subscription cost; heavy interface. | | ETKA (VW/Audi) | Extremely precise for VAG group; updates weekly. | Only works for VAG; no aftermarket prices. | | EPC (Mercedes) | Deep vehicle history by VIN. | Motornummer search is secondary. | | TECDOC Motornummer | Uniquely allows search by serial number across all brands. | Requires training to use advanced filters. |
The Verdict: If you work on multiple brands (independent workshop), TECDOC using the Motornummer is the only viable solution. If you are a VW specialist, ETKA is fine, but TECDOC gives you the cross-referencing to aftermarket brands like Febi, Meyle, or Vaico. Result: The customer returns 6 months later, no
