The battery warning light means the alternator is not charging the battery. And the check engine light is probably for the same issue.
Have you had the charging system checked ?

SOURCE: 97 vw jetta w/aftr mkt. alarm drains battery and disarms on own?

My friend you are faced with a catch 22 problem. The first thing I would like to know is, who installed the alarm system? Did you do it or was it professionally installed. If it wwas professionally installed I would go right back there and discuss the problem with them. It very well could be a defective unit. If you did not have it installed professionally I would disconnect the alarm and see if your battery still get's drained.If so, then the alarm is not the culprit, and you have some hunting to do. If not then you have some testing to do.Next what type of alarm is it? Try to google it. You may be able to find a trouble shooting guide to assist you. I know that you said you just replaced the battery, but the alarm very well may not be the culprit. It could be many other things as a loose fanbelt, bad diodes in your alternator, or some other componet draining your battery.

My engine light and the ETC light cone on when I try to start my 2012 VW Routan. What is wrong? You

Hi
Solution: This indicates a serious failure of your throttle control system. The engine computer is programmed to go into limp mode when the system malfunctions, in an attempt to limit your speed and prevent damage to the engine. It can be caused by a sensor failure, or even by outside electromagnetic interference.
May need to get your car computer reset.
All best Clive

04 model starts ok battery charge light appears then ABS malfunction I drive short distance turn engine off when I turn on just clicks I can try again and starts no bother then same thing happens

Your battery charging system is defective, the battery is going dead and that is the cause of the other issue like the ABS light. Get the charging system diagnosed.

Vw 2001 beetle engine malfunction light is on

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Common problems with the pontiac grand am mot starting

That is a pretty "wide-open" question. Not starting can be caused by everything from a low or dead battery to a malfunctioning security system to a faulty fuel pump or the fuel injection control system or ignition system problems. It can even be caused by serious mechanical failures in the engine itself. A LOT more information would be needed before anyone could tell you why your car is failing to start.

If the battery and charging system is OK, then you need to begin diagnosis of the rest of the possible system failures by scanning your engine control computer for possible stored fault codes.

I have a 2004 VW Passat the engine light came on had it diagnosed the code is P0322 what does it mean and how is it fixed? Thanks

Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stallPossible causes- Ignition/Distributor engine speed sensor harness circuit is open or shorted
- Ignition/Distributor engine speed sensor poor electrical connection
- Faulty Ignition/Distributor engine speed sensor
- Faulty Crankshaft Position sensor
- Low battery charge
- Faulty Engine Control Module (ECM)When is the code detected?The P0322 code is triggered when the Engine Control Module (ECM) detects no signal.P0322 VOLKSWAGEN DescriptionIgnition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If ECM detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.

What do the warning lights on the 2004 VW Passat dashboard mean as they are a few flashing and I don't know what they mean?

Depending on which light is flashing will determine whats wrong, normally thee are three lights that flash one is yellow check engine light, when it flashes it means a misfire and catastrophic catalytic converter failure. Red oil light means your low on oil and if it does not have a gage you may have damaged the engine and then there is several others like air bag warning light this would be caused by a defective clock spring, or a malfunction in the computer system. Your best bet is call your local dealer and describe to them your problem and tell them what lights are flashing they can determine weather you should drive it or have it towed in for repairs. Remember FLASHING RED OR Yellow light means imminent failure of expensive engine parts.

Battery light on dash is on but car is still going - only got a new battery 4 months ago - car is still driving - Imported 01 Mazda Premacy

The battery light on your dash indicates a charging system failure, that would be the alternator and its wiring. If you are still driving the car and haven't needed a jump start in four months, you probably have a malfunction in the circuit that checks the charging system.
Check your voltage at the battery with the vehicle running and if it is between 13.5-15 volts i wouldn't worry to much about it.

MIL dashboard warning light came on in my 2005 VW Beetle. What could the problem be?

this is the Malfunction Indicator Light, also known as the check engine light, this light is to alert u that a problem exists in the electronic controls of your engine, transmission or emission system, or a combination of all three, u can go to any Kragen or Autozone car parts store and they will run a test to determine the cause of the light free of charge.
