Hi all I have been directed to your good site by links I've searched and have signed up and hoping I could call on your expertise to help a new member out with my range rover. Apologies of this might jot be the correct place to ask a question I'm just getting to grips with your site. I have a 4.6 thor engine had a battery low issue couple of weeks ago and after charging it wouldn't start turns over but no spark or fuel. I read codes as I have a launch x431 system as mrs has a Renault.... yeap thought better of keep taking it to dealers !! The range had crank sensor fault so proceeded to change it but still no start the only other fault i am getting now every time is immobiliser incorrect code data a. Would this by any chance be a becm to engine ECU sync issue ? Possible the crank fault was either coincidence or a ghost fault as it couldn't start anyway due to un synced codes. The key works cranks and opens locks doors remotely etc was driven fine day it would not start then when I went to go back out but battery was low so took of to recharge. I have read links talking of a syncmate hoping might be a good samaritan on here close to oldbury in brum who could help .. beer tokens obviously on offer.
Thanks so much for your help it's a sad day when the range is parked on the drive and I can't use it :-((
