One problem related to air brake abs warning light has been reported for the 2003 Jaguar S-type. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Jaguar S-type based on all problems reported for the 2003 S-type.
The abs light and a message stating abs fault/park brake fault would display while driving at highway speeds. When the car was stopped and re-started, the message would re-set. This happened several times (> 5), and the dealer did not fix for some time because they never got to see the message. We noticed that the problem occurred during or after a heavy rain. The dealer thought there might have been a problem with a sensor on the wheel. Ultimately, the dealer replaced the abs module.
