Hi Everyone,

I picked up an '07 Q7 a few months ago. Someone has done a poor job of installing face lift headlights and tail lights, so please disregard the light faults (this is on the list of things to resolve)

A couple of days ago the central locking stopped working. After looking at the scan, I am thinking it is a faulty/failed battery that is causing the issues. Looking at module 061 and blocks 1, 4 and 10, the voltage of the battery with the engine off is only 11.65V. With the engine on I get a good 14.3V at the alternator and 46A, so it looks to me that the alternator is working ok, but the battery is not holding a full charge.

The above indicates to me that a failed battery is causing systems to shut down and cause my central locking to stop working. Ergo, a new battery should fix the issue.

However, the car is doing a couple of other weird things, which don't seem to me to line up with the idea that systems are shutting down. When you turn the ignition off and remove the key, the MMI stays on, the tail lights stay on (if auto-lights are on), the power windows continue to operate and the steering lock does not activate, almost as if the car has not recognised the removal of the key from the ignition. Over the last couple of days we have had to manually turn everything on/off to make sure the battery isn't further drained. I'm worried that the battery might be a symptom of some other fault, rather than the cause. Some sort of fault with the ignition switch causing systems to stay on, draining the battery etc.

Any thoughts on whether I am wasting my money replacing the battery first? Do the symptoms described sound like issues related to a battery failing, or is the low battery voltage a symptom in and of itself? Any thoughts or insights would be greatly appreciated.

Thanks.

Hello,

Any thoughts on whether I am wasting my money replacing the battery first? Do the symptoms described sound like issues related to a battery failing, or is the low battery voltage a symptom in and of itself? Any thoughts or insights would be greatly appreciated.
03041 - Energy Management Active

- You may not be wasting your money (or time), especially if the battery was already replaced once before and they did NOT adapt the replacement battery to the vehicle, now the system thinks there is a 12 year old battery in there. And if the battery is about 12 years old and is an AGM, it maybe time for a new one.


It is not necessary to use a Audi Battery, you can use an exact replacement size/ratings battery and when you adapt the new battery, just keep the values the same except change the battery serial number by a digit, that way the battery management system know there is a new battery which is of the same ratings.

Battery Replacement



Hope this helps,

How quickly does the battery voltage drop after you shut down the ignition?

If you've driven the car for a while, meaning the battery is presumably well-charged, and it drops below 12.0V quickly, either the battery is shot, or there's excessive resistance in the leads to it.

Have you checked the condition of the battery terminals? Have you tried charging the battery using a separate charger and then monitoring its voltage afterward without applying any load to it?

Thanks for the quick response guys. Out of interest, how can you see the battery is 12 years old? That doesn't surprise me as it has a genuine battery in it and there is no way the guy I bought it off would have installed a genuine battery. When I l saw the battery was genuine it made me think it must be pretty old.

Yes, have checked the terminals etc. and everything looks tight and clean. It basically drops below 12v straight away, although we don't really drive it that far. I will go for a drive now for a good half hour and check the voltage then. Your suggestion to charge the battery externally was on my list, but I don't own a battery charger, so was tossing up about buying a charger versus just going straight to the new battery.

I'll check the voltage after a drive this morning and if it quickly drops below 12v I'll replace the battery. I'll post back with what I find.

Cheers,

We cannot. But based on what you posted there, it looks like the car thinks it's the original one.

You could go to [Applications] -> [History Data], select module 61, and click [Start]. When VCDS finishes (not long), click [Save] and post the data here.

but I don't own a battery charger
Given how hard modern cars are on a battery, and how important the battery is, you should. Everyone should.

I went for a longer drive this morning and the voltage dropped pretty quickly after turning the car off so I replaced the battery. The new battery is definitely stronger, with the voltage holding above 12v for longer after shut down, but unfortunately the battery was not to source of the issues.

Below lists some of the symptoms/observations:

-When I insert/remove the key from the ignition there is no change in state of the vehicle. The steering lock doesn't engage/disengage the MMI stays on, lights stay on etc.
-Central locking does not work from the remote
-If you wait for the cabin light to turn off, pushing the unlock button on one of the keys causes the cabin light to turn back on (indicating the keys are actually communicating with the car)
-If I undertake the tests in module 05, I can get the key ignition lock to click on and off, but I cannot get the steering lock to actuate.
-With the new battery the battery voltage is 12.05v in module 061 (after working on it for a while with the engine off), but the supply voltage to the ignition in module 05 is only 11.6v. Could this be an issue with the ignition, or perhaps an earthing issue, or is this normal?
-in the advanced block measuring in module 05 it states the locking voltage to the steering lock as being 0.28v, but then states the minimum locking voltage as being 7.2v.

It seems to me that the car is not sensing the keys being inserted/removed, although I am lost as to the reason for this. Also, the fact I cannot get the steering lock to activate using the output test in module 05, seems to indicate some potential issue there.

Below is a couple of screen shots, an updated log after the battery replacement and the history data log. Again, I appreciate any thoughts or hints on what could be going on.

Cheers.

-When I insert/remove the key from the ignition there is no change in state of the vehicle. The steering lock doesn't engage/disengage the MMI stays on, lights stay on etc.
-Central locking does not work from the remote
I had these exact symptoms in my A3 8V. Reason was, ignition lock was somehow physically stuck in such a way that it did not register key being taken out. Car thinks the key is still inserted and leaves MMI on and won't let you lock the doors with remote.

I had the entire ignition lock replaced (under warranty, luckily) and no problems after that. Maybe you are experiencing the same issue? Try to wiggle the key while pulling it out to see if that helps? In my case, it did. Also, when I took out the key and MMI stayed on, I could often turn it off by hitting ignition lock firmly with my fist. :D

EDIT: If there is a measuring value for this key in/out detection, maybe that would tell something. But I do not know if such thing exists in your car or not.

Wouldn't hurt to install a solar charger to maintain the thing when it sits either.

Change the battery anyway.........

Mike, you nailed it, thank you. If I get really aggressive with the key I can make it sense the key removal and then all works normally. There is obviously something mechanical in the ignition switch that is faulty. I’ll replace and report back.

Hi again everyone,

I purchased a replacement ignition and installed it and it problems are fixed.

A few points for anyone undertaking this repair:

-The ignition is a simple plug and play replacement
-No coding required
-The ignition is not specific to the key, so can just replace and not worry about keys etc.
-An ignition from a C6 A6 also works (That's where I got my replacement from)

Below is a picture of my ignition module with the part number shown.

Thanks to everyone for their time and help.
