Mr Polson 10,214 Posted March 15, 2013 Try this, to fix the A/C issue... Thanks for this issue mate, made me realise mine has come lose, may explain a few electrical issues I've been having!! Pics are uploading.... Its under here You will have the EFI comp here rather than the EST one See that dash mounting bolt up to the left? Here The earth should be on that bolt. As you can see, mine is lose, so I'll have to tighten it back down. Should be three or four wires leading into the main connection to go onto the bolt Ignore the black tape on it. Probably factory to cover any exposed wires Don't expect the fuel estimate to be accurate from what I've heard... Mine is trip comp with carby motor and it tends to over estimate massively (example, says I can do 873km on a full tank, every time I fill up). Love to see a carby XF do that on 68L of 91. Bright side is I never get the low fuel warning/beep. Share this post Link to post Share on other sites

Mr Polson 10,214 Posted March 15, 2013 Dunno then mate, you've exhausted my electrical knowledge Share this post Link to post Share on other sites
GspecZL 979 Posted March 15, 2013 My computer went bonkers for a while. Was saying i had 1km until empty when i had a half tank. Then i decided like polsons that i could get 800km from a tank. I replaced it. Cleaned up some wires behind it. Now it even keeps time! Share this post Link to post Share on other sites
