Once you have the code, you are ready to use the TecDoc system.
However, the efficacy of this system depends entirely on the data quality
Manufacturers often swap belt profiles or hydraulic tensioner designs mid-production, dictated entirely by the engine number. tecdoc motornummer
TecDoc er i konstant utvikling. Nylige oppdateringer har fokusert på å forbedre håndteringen av motordata:
Two cars with the same VIN prefix (same year, same model) can have a different Motornummer range. For example, the Peugeot DW10 diesel engine underwent a piston ring design change in 2006.
