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. Common Mistakes When Searching by Motornummer Even experts trip up. Avoid these pitfalls: Mistake 1: Confusing "Engine Number" with "Family Number" Some manufacturers (looking at you, Ford and PSA) use a "Family Code." For example, the engine might be DV6C . If you enter the serial number stamped on the block (e.g., DV6C0065421 ), TecDoc will fail. Enter only the base code: DV6C . Mistake 2: Ignoring the Supplementary Criteria 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). Mistake 3: Using Aftermarket Tuning Codes If you have chipped or tuned your ECU, do not change the Motornummer. TecDoc is for OEM specifications . Always use the factory engine code as it left the assembly line. Advanced TecDoc Features: Cross-Referencing the Motornummer One of the most powerful features of TecDoc is the cross-reference tool .
Do not rely solely on the vehicle model or the year. Two identical cars parked next to each other on the same lot can have different engine codes, and thus, different fuel pumps, different gaskets, and different timing chains. 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.
