Newbie maself and have a similar fault. 2.7d se Auto been running great the last 3 or so years. Had to turn off my ABS the other day due to the ABS constantly kicking in reducing power. Works fine now with no ABS. Car is booked in for Wednesday (non Jaguar Dealer) but has diagnostic kit to check it out.Think the sensors are not talking ?? Worried though as Gearbox Fault now displayed but no code. Turn off engine then restart and clears. Noticed heavy duty smoke threw the gears when giving it the "Gypsies Warning" and felt it has run a lot smoother. Turbo's replaced 30,000 or so miles ago. Surely not again ?? Just a wee tad worried !! :( Help and views much appreciated ......... GAS ........ ;)
