Yep and the battery and alternator have been checked, all ok.

thanks guys, already checked the boot area, dry as a bone, is there a control module which is common, ie can affect all the systems mentioned?

I have a 2.7 diesel S type automatic which is displaying intermittent faults ranging from a simple non start, ie turn the key and absolutely nothing happens, to various erroneous warning lights and messages when the car does decide to start! including Gearbox, parking brake and DSC faults, sometimes the power steering will pack up, sometimes the gearbox will not change up, sometimes the tacho or speedo will not work, sometimes one not the other will . My engineers have inspected and run diagnostics to no avail, once the car does start, the fault indications and gearbox/power steering malfunctions, do fade away, when the engine has run for a while and stopped and restarted. I suspect water in the electrics somewhere, but has anyone any ideas where? Anyone any ideas?
