2004 S Type battery drain please help.
Hi I have a problem with my 54 plate S type I have a 3.4 amp battery drain so far I have pulled all fuses and found out that fuse 20 in the fuse box drivers side is the fuse thats pulling the drain but now I have hit a brick wall my manual book says...
Logic supply to instrument cluster,climate control system,front and rear electronic module,electric parkbrake.
And help and advice would be great and if anyone knows of a good place to take the car to get it sorted in the birmingham area would also be great.
Thanks in advance a frustrated Lee

If you can read circuit diagrams then download, for free, the diagram for your car at Jaguar electrical reference.
There is quite a lot coming off that one circuit and you should be able to narrow it down.
Have a look to see if the little flap in the ignition barrel is closing when you remove the key.
If you have auto lights and wipers, switch them off. Also switch off the steering column.
Hope this helps, if you need any help with the diagrams, just ask I will be more than happy to help.

Also bear in mind that when the car decides to "go to sleep", which is about 40 minutes after you walk away from it, the battery voltage is monitored by the system.
If, at that time, the battery voltage is "sensed" as below 11.7V the car simply will NOT go to sleep, and continues to drain "about 3amps", until death arrives.
This was the case with "her" Silver S type. It took some finding, as I was looking for all the obvious, as in my older Jags, and it was simply a battery past its use by date.
These are "juice hungry" cars, as are most late model makes, and the battery is more important now after shutdown than its ever been.

I left that fuse 20 out for about 4 hours to confirm that was the fault but when I went back to the car it was dead I could not even open the boot off the key fob BUT the battery had not drained at all I popped the fuse back in and the car fired up...
As you can see I dont really know a lot about what does what

Your OP failed to say you had a diesel. They are very significantly different than any other S-Type and not in JTIS. They have all the usual faults well known on here and a lot of others that are on the UK forum (no diesel S-Types in USA etc). For electrical testing you can probably get away with using the non-diesel guide but always keep in mind it does not cover your car so you can have extra or different issues.

Not been able to get out to the car today been to busy but I have been told to take it to a place in Derby called performance elite jags might pay me to get a price of them and let them check it out properly as I am not confident on being able to id the problem fully and fix it and I need the car I have ordered an isolater for the battery just for now so I can use the car and not get stuck somewhere.....

Hi Lee
I have the same model on an 05 plate. FYI there is an independent jag specialist in Stourbridge which has an excellent reputation, can't give you the name as I am away out of the country till mid January, but I am sure they would come out on a google search.
Hope this helps
Best regards
