Rear Speakers Buzzing

Hello,

I've just bought a '08 Octavia Estate L&K from a Skoda dealer on Saturday.

When I got into it yesterday, the rear door speakers near the door handles were making a loud buzzing noise. The radio was not on and I didn't have the key in the ignition. Switching the radio on didn't stop the noise.

The noise didn't stop whilst I was driving it but when I went out later in the evening to check a couple of hours later it had.

I've phoned the garage but they hadn't heard of this before so they're going to look into it.

I've looked in the forum but only found one mention of this about 4 years ago.

Has anyone had this with their car? Any help would be great.

Thanks,

Ian
