Hi, My ABS fault light came on along with DSC not available. The car was due its MOT and failed because of this. I drove it to an electrical specialist who diagnosed a faulty abs Sensor on one of the rear wheels. I went to pick up the part from Jaguar and on the way a new light saying gearbox fault came on. The car clunked and jolted every time I put it into gear.
Anyway they fitted the new sensor and all problems went away with no new gearbox required.
