    Checked the battery terminal voltage when engine running?

    Checked the connections to the alternator?

    Sounds like the alternator voltage regulator isn't working, yet the Auto-Scan shows a sensible battery voltage of 13.7/13.8V - was this with engine running or just ignition on?

    Do you have evidence of actual overcharging, as in a sustained >= ~15V measurement at the battery with a multimeter?

    Sometimes batteries die of natural causes, and sometimes they do it ungracefully.

    +1 on all of the above. Voltage looks normal for a car that's either running, or on a charger. Which is it?

    I was driving, i noticed that the Rpms were at about 1.000 like it was charging the battery if I had low voltage. Next I noticed the smell from the battery acid and then my dash beeped 3 times and the speedometer dropped to 0 and then jumped back up to my actual speed. Plugged in The cable and laptop while still driving and this is the result. Right after I pulled this Cable gave me a red light immediatly unplugged it and parked. From the time the smell started to park is about 3 minutes.

    As soon as I got home I pulled the battery because it was leaking and swelling.

    I’m going to check all my wiring and connections today to verify I don’t have a shirt to ground etc. I’m more than likely going to get a new battery and I’d like to verify the coding for the cent elec last 8-10 bytes with a good reference scan. This car was borrowed for about 7 months while I was deployed and since I’ve had so many gremlins since I’m concerned he tweaked shit he shouldn’t have since I know he messed with some of the comfort features.

    And just prior to this the vehicle was torn apart for about 2 weeks and the battery was low when I installed it. Could the age combined with the abuse of charging it back up and manintenance on the vehicle have just killed it? I’m sure I didn’t follow VW procedures when I removed and reinstalled it.

    With the current evidence of a sensible battery voltage, and the chequered history of the car I would go for a new battery.

    AFAIK the only component on a car that can cause overvoltage is the alternator, and there's no evidence of that.

    Has the car ever been jump started? If so was a normal car jump starter used or a truck one? I've seen BIG problems caused in ports when cars have been jump started with a truck (28V!) jump starter...

    Hello,

    And just prior to this the vehicle was torn apart for about 2 weeks and the battery was low when I installed it. Could the age combined with the abuse of charging it back up and manintenance on the vehicle have just killed it? Im sure I didnt follow VW procedures when I removed and reinstalled it.
    You do have a fault code in the [03-ABS Brakes] that would indicate there was at one point in time an 'over voltage' condition.

    00668 - Supply Voltage Terminal 30
    001 - Upper Limit Exceeded


    To answer the question about the battery, was it "killed"?, maybe?

    Based on the VIN number, the build date is 11/2014, so if this is the original battery, it 4+ years old, I have seen less than 4 year old batteries fail.
    Any abnormal stress on a battery can cause it have a shortened life, just really depends on the battery, type and life it has lived.
    As per the parts catalog, the original battery was rated at [280 A (60 Ah)] part number: [000-915-105-DE]

    You can take the battery to an auto-parts store to have it tested, many store use modern test equipment to help verify the overall battery condition.

    After you figured out the battery condition, I would suggest to verify actual voltage at the battery, with the vehicle running, using a decent volt meter. If that is okay, then check the voltage drop from the alternator (+) terminal to the battery's (+) terminal while loading the charging system by turning on large electrical consumers.
    You should no more than a 0.5 volt voltage drop volts and charging voltage should not exceed 14.4 volts.

    By the way, I have replaced failed voltage regulators in alternators for over charging problems before with success. PartsLink24.com shows the regulator is available separately [04C 903 803].


    Hope this helps,

    drpeter
