Great news Steve and thanks for the update.

Here is the electrical manual for your car, figure 05.1 refers. http://www.jagrepair.com/images/AutoRepairPhotos/CarPDFFiles/JaguarXType/2007XTypeElectrical.pdf

The most likely cause of a drain that large is the “alarm chirp sounder”. The internal batteries degrade over time and short out causing the drain. Disconnect it and then see what happens.

If you go through this page to find the one you need you will at least get the part number, it may make it easier to find. https://parts.jaguarlandroverclassic.com/parts/index/part/id/250.1121.2713.12497/brand/jaguar/

Check relay R3 and fuse F23 30A in the auxiliary junction box as a first port of call.

Here’s one in Ireland; https://www.ebay.co.uk/itm/167490959257?_skw=Jaguar+XF&itmmeta=01K16GVZ0BKP2FGF1DCTN720MC&hash=item26ff3d3799:g:fX0AAOSwC2JoFM~4&itmprp=enc%3AAQAKAAAA8MHg7L1Zz0LA5DYYmRTS30mRRdfuYUeC1zkW7Odi%2BQUKrOukr%2F9ZbOgBSyrqqZc2VX9unfHiow0%2BnbViA4eCiPPllWv8Qb6iXZMyEoTO0bLNbyTJiQJq%2BdnAoO4fRZ44%2FS8gs12ls0G2TJ%2B4X7%2FlUPob4EEvABl11hmBXCr3oWQzJlASu%2B0p28KJwqgCyDaJ3%2BWlYyqS0tc%2FLPt%2FOV2SuEqEpP8bd2YuCronU7K5m2lQgoo2ZaKvHBTjOeP088Ufr5Td1%2B%2FfMmsDqKnHzLrVc6Bd8nVU0ZVH4RrBCnrLU5T5Q%2FQceQCia5ryZimx7dhtSw%3D%3D|tkp%3ABk9SR6zw79CJZg

I would suggest you check the “alarm chirp sounder”. This is by and large the most common fault with discharging batteries. Disconnect it and then see if the battery dies.

Hopefully this will help you out; airbag code 16 indicates a passenger seat weight sensor CAN fault. This means there's a communication issue with the sensor that detects if someone is sitting in the passenger seat. The CAN (Controller Area Network) is a communication bus that various modules in the car use to talk to each other, and the fault code suggests a problem with the signal from the passenger seat weight sensor being transmitted over the CAN. Here's a more detailed explanation: Passenger Seat Weight Sensor: This sensor is located under the passenger seat cushion and is designed to detect the weight of a person sitting there. CAN Fault: The CAN bus is a communication network that allows different modules in the car to exchange data. If the passenger seat weight sensor is not communicating properly with the other modules (like the airbag control module) via the CAN, it will trigger code 16. Possible Causes: Faulty weight sensor under the seat. Wiring or connection issues in the passenger seat weight sensor circuit. A problem with the CAN bus itself (less likely). Faulty passenger airbag module.

This is a common fault on the XK8 and here is a video showing you how to repair it.

Hello and welcome Julian. Try this one; https://britcar.com/product.php/317608/5497/boot___trunk_release_button_gold___ruby___jaguar___xj_1995_to_1997_daimler_variants

Try this;

The noise is mostly likely the aspirator fan behind the dashboard. This picture shows how much dust can accumulate on the sensor part at the grill. Removing the dash surround and thoroughly cleaning and blowing out with air may help.

There are places that can repair your existing one, unless it’s too far gone.

Hi Ed, here’s one for sale; https://www.b-parts.com/auto-parts/electrical-and-electronic/instrument-cluster-jaguar-xk-ii-coupe-x150-42-xkr-7w8310849he-2006-2007-2008-2009-2010-2011-2012-2013-2014-15262054

This will help you out and also aid in understanding the system. http://jagrepair.com/HydRoofManualOperationxk8.htm

Hi David, You May have to manually close the roof fully in order to reset the system.

Hi David, The quiescent drain for our cars is 30 milliamperes or 0.03A so not very high at all. This is also easily checked. I would ensure the day before you leave, you allow your CTEK to fully charge the battery. However, it would be worth having the capacity of the battery checked as it may have dropped from lack of use. Lead sulphate begins to form at 12.4v and its these sulphites that strangle the battery.

You’re welcome, Paul. If you intend to remove the battery then always the negative first.

Hi Paul, With your car there is no problem with disconnecting the battery as you don’t have the BMS (battery monitoring system) fitted. I have the icarsoft i930 for mine which is perfect for what I want and it will tell you which sensor is at fault. If you go the icarsoft route then make sure you buy from a reputable source and it is Jaguar specific.

As shown in the video, no specialist tools required to change the sensors. You can always disconnect the battery to be completely safe.

Hi Paul, A code reader will tell you exactly which part of the system is flagging the fault. Usually it will be one of the 2 impact sensors at the front of the car. On your car, both can be changed from the top without having to remove the nose cone. This will help;
