Electrical problems with MK5 Golf

[shonekapone]

Hello,

New here and not sure if this was already posted or not...

I have a problem with my Golf when starting cold & hot, it makes a loud bang or a clunk when it's about to start sometimes, i fixed this problem recently by buying a new battery and it was fine for about 3 or so months, but now it's returned again, i'm not sure if it's something electrical or mechanical. I noticed also when i'm about to park in my garage i usually have the windows open and just as i'm about to turn into the garage i start putting up my windows and as i turn the windows stop half way. Again not sure if this has something to do with it..Been to a mechanic and he couldn't figure it out, so just thought someone on here might have the same problem.

Thanks

Could be many things.

Windows might need to be reset, since the battery was replaced. Heaps of info out there on it.
