The Mercedes-Benz Digital Service Booklet is also known as DSB. It is used to document maintenance-related service data after workshop work has been completed. The workshop enters the information digitally. A digital service report can then provide proof of the entry.
Many Mercedes-Benz passenger cars use digital maintenance documentation instead of relying only on a paper service book. An entry may contain the service date, mileage, workshop, maintenance operations, inspections or information connected with a service interval.
DSB support is not the same for every vehicle. It depends on the model, production period, market and vehicle category. It also depends on whether the workshop was able to register the visit digitally. Some older cars still need offline or paper documentation.
An absent entry does not show why a record is missing. Work may have been documented on an invoice or in another workshop system. Compare the digital history with receipts, inspection papers and information supplied by the seller.
