Well good things don't last long! Car ended back to draining the battery - typically 110>180milli amps over an extended period after which time the controllers should have been shut down by the BCM! So I went to talk to my next SEAT dealer, who was willing to believe that it might just need a software update or patch. The car was in today and unfortunately there is not updated J519 software available for that car!! The worksheet records a battery drain of 0.25Amps after 20 minutes - but no clue as to if they consider this to be excessive though it is a lot different to the 0.005Amps to recorded when the systems were asleep or the 0.117Amps I recorded when the systems are awake. Strange that my recorded asleep and awake drain currents agreed with what the now closed SEAT dealer found, it was just that they never recorded the systems staying awake which I did and was probably the reason for the battery getting drained over a few days of not being used. This latest SEAT dealer has sent SEAT a technical inquiry and hopes to have a reply in 48 hours or so - I hope that something good comes out of that, as that enquiry is meant to be fed into a common "pot" of knowledge world wide!
Edit:- I can force the car to go to sleep by removing the heavy red lead from the battery top fuse links area, then refitting it a few minutes later, every time that I've done that I have managed to drop the drain current down to roughly 5milli amps - for some time, I've yet to actually record how long, over a couple of hours once, ie I monitored it over 2 hours and it was still roughly 5milli amps.
