Do you just undo the 3 bolts holding the clamp/washer bottle support and lift it out? I think mine has died a death, I had to jump-start it this morning.
What a total sod of a job that was! I had to remove some air ducting and the plastic radiator surround to be able to get the battery out but after half an hour of swearing the new battery is in. Thank goodness for ratchet spanners or it would have been a whole lot worse!
Knuckles are fine actually, it took me a while to work out why I couldn't get the battery out between the rad and wiper motor until I realised the surround came off!
