[PsYcHe]

Just dropped the car off at Mackie's this morning to be phoned about 10 minutes later with the joyous news of:

ZF recommend an update for the 6-speed boxes in these, so not only is there a software update (more time), but to go with it, they recommend changing up to the Lifeguard 8 oil which is more expensive.

I did have the option to stick with the Lifeguard 6 and no software update, but there have been a few cases of gearboxes shuddering when coming down the gears as they age which is why ZF recommend the update. He did say it wasn't essential, but it did add just shy of £200 to the price!!
