Sounds like your alternator and/or alternator bushings/bearings may have failed or are failing which can/will affect electrical system. The accessory belt (runs more than the alternator) will squeal when under no load like park or neutral. If the bearings/bushings fail in any accessory on the belt path the same noise can occur.

SOURCE: passat front screeching noise when rolling in gear

The loud screeching sound is made on purpose!

The front brake pads have a metal "screecher" that rubs against the brake rotor (harmlessly) and makes a screeching noise to warn you that the brake pads are worn to below specification.

Replace the front brake pads with "SEMI-METAL" pads because you mention "hills". Semi-metal brake pads have the best wear life and they remain "cool". Hot brakes don't grip. Replace them soon so you don't have to replace the rotors, too.
Check the rear brakes, too. The rear brakes don't have sensors.

Hope this helps!

If the belt is not tense enough it will squeal, so make sure it's tight enough. Otherwise you can use a stethoscope or long screwdriver up to your ear to isolate the source of the noise.

Sounds like the alternator bearings have gone away, but, you need to physically check the source of the noise. (I can't do that from here).
It also seems that you may have more than one problem going on there, possibly a bad ignition switch and also a blown fuse or bad body control module. As far as why the noise seems to be only when the engine is "freewheeling" may have a lot to do with rpm change and loading when in gear. I would go after the obvious alternator problem first, then sort out the remainder later.

Loud screeching noise coming from car after stops.


the screeching noise is most likely caused by a slipping belt or pully. transmission probably needs fluid and filter changed.
