Disconnect earth lead first- reconnect last. Located nearside front wheel arch. Remove 4 screws cover comes off. Battery now in view. Easier with wheel removed. Battery literally behind passenger footwell.
thanks bobd. Is it realistically possible to do it without removing the wheel??
on another note - just noticed your car on your profile that you have colour coded front gills in the air ducts - did you specify this yourself as all the sags I've seen these are black??
