Well the X went into have the front active anti roll bar replaced last week, because I was getting a lot of extra front suspension noise, and I told the dealer about the flat battery, which happens every weekend now, despite the battery getting a good charge after a long drive.
So he kept it in over night to check it, and he said he could find no fault, and says he put it on charge overnight - 'great' - I could have done that, and guess what , another flat battery this weekend, why dont these idiots listen to what you are telling them !! ? Grrr..

So now I'll need another dealer visit to get the battery replaced !!
