'Battery Not Charging' Warning Came On

A couple of days ago the 'Battery is not charging' warning appeared on my display. The circumstances however where a bit unusual. My wife was in the supermarket and whilst sitting in the car I was reading up on and adjusting various settings (I've only had it a few days). I say unusual because I'd start the engine, explore some features and then switch off. A few minutes later I'd remember something else I wasn't sure of and start the engine again to experiment with the settings. I must have done this three or four times without moving the car.

This warning signal appeared but, as soon as we drove off, it disappeared. We stopped at another shop shortly afterwards and I once more sat in the car only for the warning to appear again. We drove off, the warning disappeared once more and since then, having driven it about 150 miles in three or four separate journeys, it hasn't reappeared and all seems fine.

Could I have upset the engine management system with all my starting and restarting whilst stationary? I checked the obvious things, such as the battery terminals and all seemed OK and the battery was fully charged at the start of the journey in question.

However, the most annoying and exasperating thing in all this was the dealer's reaction. I phoned to ask if I could speak to a technician just to ask if they had any experience of this and was told that I must bring in the car where they would do a 'visual inspection'. Don't you love management-speak? God knows how they'd do an inspection without looking at it!

I asked what the case would be if I lived a hundred miles a way and had to take in the car only to find that a mechanic will tell me that there's nothing wrong and that he could have told me on the phone that this is something that they'e come across before and that nothing needs fixing? I was told quite firmly that it would make no difference, they do not give any advice on the phone and I must go to the dealer.

I said that I was most unhappy about this policy and she told me that she's see if anyone could phone me - no one did!

I find it staggering that dealers are so frightened of possibly giving wrong advice that they won't even talk to you on the phone. I never had this problem with Mercedes who would happily speak to me. Yes, they may well have then told me that I need to take in the car, but at least they'd discuss the problem first, and on occasions, tell me that there isn't a fault and save me a long journey to hear the same thing face to face.

I'm going to phone one or two more dealers within a reasonable distance and if I can find one that is more accommodating it's they who will do my servicing and it's where I'll buy my next car.

My first thought would be the one you had, the system got in to a muddle which no doubt a period of rest cured.
You don't say which controls you were accessing but many can be adjusted without the engine being started via the Home screen.
As for the dealer, well that is disappointing and I am sure more to do with your not knowing the name of an individual that would be able to get the information for you, the sales person with whom you dealt would be a good starting point if you don't know anyone else. I doubt that a technician would be available in any dealership at a moments notice but the after care manager should be within a reasonable time.

The low battery voltage signal was probably activated. It is generally a bad idea to repeatedly start the car and run it only for a short time. Modern cars don't like even momentary low battery voltage. As the lead acid battery is a little chemistry set it does take a short period of time for a partially discharged battery to recover full voltage. If outside ambient temperatures are low this can take a little longer. My guess is during one of your repeated starts the battery voltage momentarily dipped below the magic number and triggered the fault message. This should self clear if the battery is in good shape.

How old is your battery? After four years of faithful service any battery may fail quite normally. Most last five years or more but some don't. Next time it is convenient have a service shop perform a load test on your battery. This five minute test is simple and reliable. If your battery fails this load test just fit a new one. Likely you will replace the battery at least once in ten years. It is false economy to hang onto a failing battery, too much depends on this vital component nowadays. Also, a failing battery may place extra load on the voltage regulator in the alternator. As I say, deferring replacement of a suspect battery is false economy and can save you only a few pounds at best. At worst it can cost you more than a new battery, for example a single tow or missed flight costs far more than a new battery, much less the opportunity cost of premature replacement. Out here we easily find out when our batteries are weak enough to need replacement when the engine won't turn over at minus 30C! Our equivalent of your AA or RAC tow trucks carry a supply of common battery sizes to reduce their overall costs by roadside replacement rather than a tow.

Finally, many functions can be operated with the ignition switched on. It isn't necessary to start the engine. Only starting the engine draws any significant current out of a battery, especially a diesel. You are much better off not starting the engine if you merely wish to check functions. Unless you start the engine the battery won't notice the modest current draw for weeks.

My car is nine months old and the battery was well charged when this happened. And of course it wasn't telling me that the battery was low, it was saying that the battery wasn't charging, implying that it wasn't receiving a charge.

I think that I must have fooled the engine management system by starting the engine for short periods. I'd only had the car a few days and for most of those it was snowed in and I hadn't really got to grips with everything. In future I won't start the engine if I want to fiddle with the settings. Lesson learned!

Just had exactly the same scenario this weekend (hottest Saturday or even day of the year). Car driven 35 miles In morning, parked (while I watched Lions match) then 6 miles and 30 minute stop then return 6 miles and 15 minute stop then driven 2 miles and warning light on. Called Jaguar assist, they were going to send someone but were OK for me to try drive car home as no other warnings. Light remained on for next 35 miles home... called jaguar assist and they send guy to look at the car. He started car (which indicates after 35 miles that battery wasn't dead as you'd expect) then checked charging with voltmeter, seemed ok. I asked if there would be a diagnostic record in car system he aid no. Seems odd to me, if a system bothers to generate a warning message it may as well be logged (no? too obvious?)

Car now going in to dealer tomorrow for a check up, I didn't try the car on Sunday and the message didn't show up this morning (Monday). The car is 3 months old, it has done 2500 miles the battery should not be faulty. I am concerned about the build quality. I said when buying the car if it was going to be as reliable as my 10yr old Volvo I would be happy... so now in 3 months it has as many issues as I had in total with my Volvo in my 6 years of ownership, clearly I'm not happy!

As expected nothing found. However a wind noise issue that they couldn't find before has now been "found" so they are keeping the car a few more days while they wait for a new door seal to arrive then be fitted (old one had a split in it?) and during that time they will spot check the battery charging status.
So I will know at the end of the week if the noise is sorted (it always kicked in at 35mph), and I do hope so! As for the battery, well I suppose its a glitch, annoying and worrying but not much I can do. If the battery is drained then it will become an issue. Shame, I like the car, but I worry about reliability though!

Wind noise not related to door seals is said to be caused by the door mirror design. This was changed for facelift cars 2012 and up. My new 2013 has no wind rustle sounds coming from the door mirror area of the drivers door seal, unlike my 2009 which always made a rustling sound at speed as if air was leaking past the door seal right where the door mirror is mounted. That's wind rustling not cattle rustling which is generally silently achieved.
