Thanks for the response lairdscooby . Will look into it . I had a replacement alternator and new drive belt fitted when this began so that's probably it . The rectifier you mentioned , is that a replaceable part ? Can any garage do it or is it a jaquar part ? And how much labour is involved? So to bombard with questions but I just need to get this sorted before any more damage is caused . Many thanks in advance 

Can any jaquar technicians advise what this code means and any easy fix to get rid of . Getting battery warning light at the same time even though battery is being charged .
