Howzit guys. The battery on my golf 5 2.0 is always going down. The battery can't be at fault cause I changed it about a year back. The only thing I did recently was put a golf 6 gti MP3 player on the car but I'm not sure whether after that then the battery started going down. Any clue what's wrong guys?

TIA

The golf 6 radios will draw the battery if you dont code the car for it or have the correct gate way installed.Remove the radio and check it again.

You need to do the following.... I did this fix on my car and the battery is 100% fine. I also have a rcd310 the newer spec mp3 vw radio.

Used this technique to have a small harness made up to cope with the issue explained below...

I have been using this method for over a year now with not problems at all."

Step 4:

does ur car having a tracking device?

Wouldn't be the tracking device. The golf 6 radios draw more power from the battery than mk5 ones would, even with the car switched off it draws power. You can either do this fix or buy a new CANbus unit from vw or a scrapyard and have it coded via vcds.

Thanks for the help guys. Will try that fix tonight

Golf 6 RNS510 unit battery drain issue fix & DIY fix.

There's an even neater way IMHO.

It would be neater to open the fuse box and move the radio fuse terminal to a switched slot.

Just move the radio fuse - open the box, remove the wire/plug from where it is, to the switched area. Then plug the fuse in normally.
