For a battery to go dead on you like that there must be something draining the battery while the vehicle is switched off. It could be something like a trunk light which is not switching off or a short across some circuit that does not show up on any light. The first and easiest test is to disconnect the battery negative cable whenever you park the vehicle overnight etc. and see if the battery still runs down.
As a more positive step and if this does not affect the alarm, disconnect the positive lead from the battery and wire a bulb like a tail light bulb, between the terminal and the removed lead. The bulb should light up. Make sure that everything on the vehicle is switched off, the bulb should still be lit. Remove and replace the fuses one by one until the bulb goes out. That is the circuit that is running your battery flat. Check all the components on that circuit until you get the light to stay out and your problem should be fixed.
Check your charging system. With the engine running at about 2000 rpm, a volt meter across the battery terminals should read around 14 to 14.5 volts and drop to about 13.8 volts with the engine at idle. If this does not happen, the charging system may be defective. Even with lights on the voltage should climb, but will drop lower at idle.

Battery draining in my audi a4


the battery to get drain means that you have a power leak somewhere. Check sometimes the light in the boot still on as the off switch is faulty or the door is not closing it. What to do first remove the bulb for a night and on next day starts fine the repair the fault. Also sometimes light might still on current to a very low power where is not spot as it happened to me on a customer Alfa Romeo 147,having power leak on the rear left light very low currency and how spotted,left in a very dark place and noticed. If you think is rather difficult to do something take it to an expert electrician to check every close reason for power leak.

Every time it rains water comes into the passenger side footwell.My Audi is a 2.6 convertible 1998 model. any ideas how to solve this problem ?


The drains under the battery are blocked causing water to come through holes in firewall. Remove battery and unblock drain to fix. Unfortunately there are computers under passengerseat carpet which will probably be damp. best to leave a dehumidifier in your car for a day to try and dry out.

Audi A4-how do i know if my alternator is bad or


START engine and turn on head lights to main beam if engine stops and battery is flat then the Alternator isent putting out 13.5 volts or 12volts so then turn off lights and turn on inn and with a test light check power lead on Alternator if you have power to alt then you have either Reg or brush problem .
Take it off and get it tested and if slightly faulty then get a change over one and refit start and recheck your head lights as they should come bright when engine runs evan at idle .

Battery dies on 2003 A4 audi


HI there,

I had the same problem with mine. Managed to determine that it was the rear brake light switch that caused a short. This meant that once the car was turned off power was being drained. We thought it might be the computer module shutting down which can take up to 10/30 minutes. But No. Replaced with a new Brake Light Switch, Problem Solved

Radio stays on.


It would be best to pull the radio fuse leaving it out for several minutes then replace it. tis may well fix the problem but if it doesn't you can remove the fuse agin knowing it will not drain the battery over night
