That's the engine in my XF - about a year ago the EMS took leave of its senses and started killing the engine dead whilst I was driving (with spurious errors displayed on the dash). Then, at one point, whist I was sitting at the roadside (having coasted to a halt safely, fortunately) looking at the manual to try to decipher the dashboard warnings the engine started again all by itself... :-/ According to Jaguar it was caused by a faulty parking brake sensor - well, if something like that can cause such potentially catastrophic consequences for the EMS as a whole the software must be so bad that I'm not surprised you bailed out... -- Andy Greener n.b.
