Noticed that the battery 0n the testing 09 is 85ahr 680amp, D3 spec says 95ahr 850amp so have ordered correct specification exide, might this make significant difference? 07 all good but elchepo compressor needed Hitachi software not direct replacement as advertised, but works fine, started on jaguar xf, spent whole day removing bumper and under tray bolts and clips seized or spun managed to remove wheel liners, then remove bumper and front part of tray as one, new clips and bolts on parts list, up on stands now, removing radiator and all front panels next, hoping to support motor and subframe with engine hoist and my gearbox lift drop it and roll the whole thing as a unit out the front, well that's the plan so far, don't have a lift, lot of hidden pipes and plugs and a sump oil leak from sensor I think, it's a challenge but going well
