Claim:
1. Method for monitoring state of health of a vehicle system of a vehicle, comprising the following steps: performing an end of line test on the vehicle system, measuring a plurality of parameter values for the vehicle system at different running conditions during the end of line test, storing the parameter values in a fingerprint file in a memory, measuring the same plurality of parameter values that is comprised in the fingerprint file at similar running conditions after a predefined time interval and storing the plurality of parameter values measured after the predefined time interval in an additional fingerprint file in the memory, adding a predefined ageing offset to the fingerprint file, where the ageing offset corresponds to a predicted wear of the system during the predefined time interval, thereby obtaining a time modified fingerprint file for the system, and storing the time modified fingerprint file in the memory, comparing additional fingerprint file with the time modified fingerprint file using a control system, and issuing a message if the additional fingerprint file deviate from the time modified fingerprint file.
