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 . 

What is your charging voltage? Often if there's an internal fault like a blown rectifier this will trigger the charge warning light. Also if the drive belt is loose it can happen plus a whole host of other causes.

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 

In that case, it's probably an old code, read the codes again, check there's nothing new and then erase them. Drive the car as normal and see if the codes and charge warning light come back.

If the code does come back with the charge warning light, you'll have to take it to where the alternator was fitted, it should have come with some sort of warranty
