Battery will not keep charge

[Chappie773]

Had an issue with my 2015 Coupe for aboutt a year. New battery fitted and new fuse box has not solved my battery draining over 1 week.
Does anyone know any electrical specalist in the Somerset area that are decent. Been to my local Jaguar specalist Swallows spent just short of a grand with no luck.
Seems to be worse when the cars locked
Any help appreciated

No courtesy lights staying on when the boot lid is shut? An Almera I had got a rear end shunt and the boot switch was displaced - amazing how much a 5W bulb can take out of a battery overnight.

No lights staying on as far as I know

I had a problem lately, are the orange padlocks on the door card going off when double locked ?
Check both sides, mine was just the drivers door.

After the car is locked, does the hazard light switch illumination in the centre of the dashboard go out after a few minutes, or stay on?

The light on the door lock was staying on till I disconnected the battery.

If the little padlock stays lit with the battery connected, then the electrical fault is likely to be in the door handle.
There are quite a few microswitches and stuff on the back of it.
I also found that because the car did not know it was locked, then the hazard warning switch light came on occasionally and would flatten the battery over time.
Steve the Jag tech at German auto centre in Sheffield solved it for me.
New handle fitted problem solved. the most expensive part was the 5 hours fault finding, would have been 2-3 times cost at main dealer.
I'm not saying this the fault you have, but it could be. My battery stayed charged with the door unlocked in a garage.
Make sure the car is double locked to check if the light goes out.

if it has had a dignostic ,check that each programme has been closed down individualy , if not thay keep running in the back ground and drain the battery, you can't just unplug the diagnostic

It was done at a Jag Specalist (swallows Rooksbridge) I would like to get it checked by someone different
Would you trust a standard vehicle electrician or should I goto dealer
