Park brake problems with s type. We have had a problem with the handbrake sticking on intermittently for a while but locking and unlocking the car has always released it until now. The breakdown chap released it by bypassing the EPB module. The auto electrician put it on diagnostic machine and said EPB module was faulty so we replaced it but this hasn't fixed it. When switching on we get " Park brake fault" and " cruise control not available". Anyone any ideas?
