2001 S type dead battery
I have a problem with a 2001 S type (v8)that has intermitment (about once every two weeks) dead battery. Battery replaced several times. No warning lights or check engine issues. No connection with days driven or not driven. Battery shows no sign at all of weakness in the morningsthen sudenly one morning its dead...totaly dead. This has been going on for about 6 months.
When jumping the battery the alarm almost allways sounds when opening the door and lights flash...The only system not functional on the car is the back-up warning sensors.
Any ideas???

RE: 2001 S type dead battery
the pre-'03 cars are notorious for parasitic drain. first thing to try is to turn everything off when you park: a/c, radio, auto wheel and seats, auto lights, EVERYthing. This may help, but if not there is a TSB on an auxiliary wiring harness that solves the problem. You can trouble shoot to find the device that is draining, but it involves looking for current draw at every accessory and electrical device...

RE: 2001 S type dead battery
pre 03 cars do have a plenty problems.. 1st thing to check .. is in the trunk.. white connector.. near battery check and see if its corroded.. if so cut it off and separate the wires.. check the easy things.. first.. glove box light on.. ignition barrel not shutting off all the way when turning vehicle off.. if none of these works then will need to be drain tested.. with an amp prob.. on the negative terminal.. that auxilary harness. does work for that problem.. but can be several other things.. ive had in the pass... seat modules ..relays... front control module losing keep alive power missing .. air conditioning module.. several things can cause battery draw .. good luck.

RE: 2001 S type dead battery
Wow..you guys are great. I did in fact find an exta wire in the trunk about a month ago...just hanging down with white connector. It was completely corroded - even impacted with crud. I cleaned it out with a scribe and tucked it away. I will go cut it off...can someone tell me what that lead is for??
I do own a multimeter and know how to use it...I've been suspicious of the glove box light and trunk lights but they seem to working everytime I look into them as culprits. The ignition barrel seems like an interesting culprit..is there a trouble-shooting method to checking that...As far a techinal advice..I've worked on my own cars for 20+ years (jags for zero years). I would self-rate my knowledge as -Troubleshooting knowledge 8/10. tools 7/10. Knowledge of Jag electical system 1/10. This one is kicking by butt. By the way, what section of the electrial harness are we talking about replacing- and what is the failure mode inside that harness that causes this in other cars?? Very very much appreciate the help thus far.
Last thing..can someone confirm with me that the alarm going off after connecting the jump cables has nothing to do with this.

I don't see an answer to this last post. Any further info on this problem, and what is that white wire in the trunk for?
I have just purchased a 2000 S-Type and the battery went dead after the car was parked in the garage for two days.

Robert, IMB, you actually have a good chance of finding the problem because your drain is so fast. Search for the electrical schematic on the forum and divide the system into major components. Park your car and isolate a chunk of components by pulling one fuse every time you park. If the battery drained, that wasn't the problem. Replace the fuse and repeat. Eventually, you'll narrow it down. It's not a labor intensive process, but it does take time. Just be methodical and you will find the fault.

Thank you all, I'm wondering if we are all experiencing very similar "drawn battery problems" why was there no "recall's ever issued. I thinks it's fair to say that the Jaguar technicians really don't know what the problem is. Like so many others when the vehicle didn't start, I later went to retrieve some items from rear seat, I had no keys in my hand, yet when I closed the door the back rear lights flashed four times yet front lights never came on

Hiya, I have just bought a 1999 stype 3.0l V6 quite cheaply from my brother in law because it has this battery drain problem,
I love the car and want to get this sorted.
I'm no mechanic but like to fix things myself if I can.
I have noticed that 4 relays in the boot stay on all the time and are always warm,
for the last couple of nights I have double locked the car at night (I don't normally lock cars as I can park around the back of my house) and in the morning the relays are cold,
I'm not completely sure I have fixed the problem yet and am still keeping a spare battery in the boot but it all seems good so far,
Worth a try before you take to drastic measures.
