Scirocco Central

So I've had my scirocco for about a year it's a 1.4 tsi 59 plate.

Two months ago I started to get a bong type sound through the speakers when unlocking the car it would then stop when I put the key in the ignition. it would sometimes bong for quite a while once the car was locked but this was intermittent and random !

I had a look on here and discovered it was a low battery warning. As you do I changed the battery last week and it stopped.

Now it's doing it again surely it can't drain it that quickly !

Noticed it's also having a caw before it turns over making me think the battery is dead again !

Has anyone ever had this problem before or know what the best think to do is ?

Cheers

Have you checked the output of the alternator to see if the battery is charging. It's also worth checking if there is a circuit causing battery drain.

Is there an easy way to do this or is it a vw job ?

If you have a multi meter you could see what voltage is at the battery when the car is running should be 14v plus
