hi i have a 2004 2.7 v6 and loveit to bits but the latest problem has got me stuck

i have stoped using it every day and brake wise it hasnever missed a beat  80 miles a day  but now changed jobe 3 miles from home so wont use the jag but give it a run once a week and use it week ends

all good untill friday drove to work great after work jumped in it drove a fewmiles to the petrol station filled up drove off and all hell broke lose abs lights on gearbox fault etc first thought low battery

but pluged my i car soft reader in and i can check codes for any part of the car except the abs system it wont conect

any idears my thought are the abs unut found a company that will rebuild it to save getting it reprogramed but will cost £200

battery is almost fully charged after 24hours so will try agaig but last atempt was @ 12.10volts so not holding my breath

low battery, put battery on charge overnight and try it then

low battery on these causes all manner of problems

if your only doing 3 miles on a diesel, it wont put back into the battery, what youve taken out on first startup

I would personaly get a smart charger like a ctek and keep it on charge when not in use, it will keep your battery tip top and you wont get any more issues

Right update ABS came back no faults checked the loom from the abs to front lights found a bad earth and now i can use the obd11 reder and now i get

steering wheel possision sensor

gearbox ratio wrong

also brought a cheap chinese vacume bleader that goes on an air line and it made bleading the system so easy

so any idears i will charge the battery again just incase
