ELECTRICAL SYSTEM NOT FULLY SHUTTING DOWN AFTER LOCKING CAR

Had a 4 year service done yesterday. This morning got in car to see message "start engine battery low". Never had this message in 18 months. I also noticed that the door lock lights and hazard warning light triangle were not switching off (after a short time) after lock up, and were on all the time, showing the system was not fully shutting down, and therefore draining battery. Having seen, on this forum, that this has happened to other members after a service and that it can be rectified by simply removing the negative connection on battery, leaving for approx. 20 Minutes, and then reconnecting. I did this (left disconnected for 30 minutes) and when reconnected the door lock switch lights and hazard warning triangle light both went out after approx. 5 minutes and 10minutes respectively (after locking car), showing electrical system is now fully shutting down. So thanks, to the forum members, for the advice, it has worked for me. Also it has saved me the inconvenience of revisiting the Dealer and being without my car for more days.

Thanks for posting this. Quite often people are given solutions and then never report back on whether things work or not. Glad your issue is solved.

This is due to the service technician (probably some apprentice) not shutting the computer diagnostics down correctly before disconnecting from the OBD.
Dreadful as this will cause a flat battery very quickly.
Seems so common with Jaguar dealers, this is something that should be overseen by a senior technician.

Good to hear...so many people can't be arsed/too lazy to write any feedback after lengthy fault finding has been undertaken.
What many don't realise is that JLR charge min £150 just to tell you what the fault is, whereas we do it all for free..


I think I may have said it before;

All you need cary is a small adjustable in the glove box to whip off the negative for 10 secs or so.

Why the heck should we have to carry an adjustable spanner to fix a basic process that a dealer should comply with though?🤔

Might be worth contacting the dealer principal so they're at least aware of the issue. Whether they do anything about it, of course, is a different matter .... :(

I did contact the dealer (Friday 14th) but you know what it is like, they have a system, and they stick to it. Managed to speak to a technician who was quite helpful but the earliest they could look at the car was next week, but that would have to be authorized by the service advisors, and as I know from experience, trying to get a courtesy car at short notice is virtually impossible I thought to myself it could be 2 or 3 weeks before it will be looked at. Mean while I could get caught out with a flat battery. Out of frustration I thought I would try and rectify the problem myself, just to get it done quickly, but it does annoy me that after paying for a service (which is not cheap) you end up finishing it off your self.

Totally agree and totally unacceptable.

I find an email to the dealer principal gets results - when my used 2010 XKR developed a "wiring fault" 4 months after I'd bought it I was told it wasn't covered by the warranty and it involved a 6 hour job (at dealer labour rates :o!) to drop the rear axle to get at and fix the wiring. My email explained how sorry I was that the warranty didn't cover it but it didn't matter as it would anyway be covered under the sale of goods act. It was fixed under warranty the next day! ;)
