Sorry if this has been raised before but new to the forum and I couldn't find any topic directly relevant so raising a new one. I have a 2.7 diesel, auto (ZF box I believe) in an S-type that I have had since new (December 06). I do around 8,000 a year - mostly motorway driving - and the car has been brilliant............ right up until Monday, when the ABS fault light ("disc not available") came on and, in what I believe is a separate problem, the day before yesterday when the gearbox fault light came on. With the latter the car seemed to be stuck in one gear because when I took it to the dealership in Chichester yesterday it stuck at 3000 RPM at 50 MPH along a dual carrageway. Dealership plugged it in and the verdict, based on the diagnostic printout, is that I have a mechanical problem and the cure is either a: a replacement 'exchange' box from Jaguar at a shade over £4000 or b: sending it off for a gearbox refurbishment at a shade over £3000. Have gone for the former, which I have been assured is essentially a new gearbox in the old casing, because of time (its quicker and I need the car (and they don't have a loaner at such short notice)) and because I am hoping that if there are any inherent faults with the ZF auto box; they have been 'developed out. However, can't help but wonder about the need for a replacement/full refurb based on a software diagnostic...... Anybody had similar problems? Any comments welcome.
