Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Does it say park brake fault or cannot apply parking brake? Does this come on while driving or right after starting? When you say locked does the parking brake engage or does t just go into limp mode where you cannot accelerate?
Ok we may have a problem with the parking brake module. In some cases the software my need to be updated. To be sure we will definitely need to know what the stored fault codes are. A Jag factory tool or equivalent will need to be used to read these codes. If no fault codes are stored then it is possible it is a bad module. Let me know.
