Warranty processing
Validity:

This workshop campaign will be carried out up to 7/16/2025 and will be completed by the specified date.
Please note that warranty claims can only be processed before this date.

Information on the working time:

Generally, the working time includes all work that requires the active participation of the service technician.
This also covers all required preliminary work and subsequent work.
The working time includes the following activities during control unit programming:
• All required steps for starting or finishing programming
• Required interaction during a programming sequence
• Waiting times until programming starts
• Random check of programming status
If no further interaction by the service technician is required once control unit programming has started

because programming is performed automatically, there is no need for the service technician to remain at the
vehicle for the entire programming time.
These waiting times are not included in the working time if the total programming time is more than 15
minutes.
If programming takes up to 15 minutes, the full waiting time is included in the working time.
