I have a parasitic draw on battery in the radio circuit in my VW Passat W8 and is not the radio. What else is on this circuit that could be the problem?

SOURCE: How do you compress the

Your Passat has screw-in rear pistons. Only the fronts will compress. For the rears go to AutoZone and use their tool loan program. Leave a deposit at the counter and they'll loan you the piston kit that will allow you to twist the pistons back into the calipers. You'll want to remove the brake fluid reservoir cap before you do this, so that you're not fighting against the hydraulic pressure in the lines. Take the cap off, and size up the proper piston tool to the caliper pistons on your car. Use the kit to screw the pistons back into the caliper enough so you can fit the new pads over the rotor, replace the cap, and pump your brake pedal several times to reseat the pads against the rotor. Then you're done:)

go to a tool store and ask for an easy-out, this is a specialty tool placed on a drill to grip stripped screws and broken bolts

If you don't have MODE and SCAN buttons ( I didn't ) you can try as above but with TP and TA - they worked for me.
