Car CD player

I have a problem with a car stereo CD player. It will play CD’s but there is an intermittent scratching sound which overwhelms the audio. It is a Volkswagen CD/radio player and it came with the car, which is a 1998 model. Can the problem be fixed cheaply and easily? Any guidance would be greatly appreciated. Thank you.

Do you get the same "intermittent scratching sound " with the radio ?
If so get a noise supression kit.Radio Shack should have one.
They basically have a coil to the power supply & I think a capicitor to the car coil.

If it’s just with CD’s & not the radio too then you probably will need a new CD player for your car.
