No tail lights or dash lights, unless I press the brake, also anti lock light comes on but will go out when I stop and restart the car....any suggestions

Question edited for clarity, 'fuse', unless you light it 'fuze'.Question moved to sub category.

If the radio has an inline fuse, it will be within 82 of the plug at the rear. They are built into the harness. Unlikely because there are three fuses covering audio.

Shifter not coming out park could be a problem with the shifter interlock system . Won't let driver shift into gear unless foot is pressing the brake pedal down .
locked light on ? Do you mean SECURITY light is lit on the instrument cluster . Anti-theft system disables fuel injectors if there is a problem .

A simple 12v test light will track this problem down.(Unless someone has been butchering the wiring,it's probably a bad headlight switch).

check earth wires for light circuits and dash

Check fuses first. Should be a fuse labeled 'Stop' or 'Brake'.

If fuses are good, climb under the dash and look at the brake switch, it's high up on the brake lever. Make sure it is operated by pressing in the brake pedal.

When you are talking about "indicators" we could assuming that your are refer about signal lights. This work with "flashers" devices.

For 1996 Audi A4 2.8L SFI 6cyl the Flasher is located in front seating area, driver side, under dash, behind dash lower panel, mounted above driver side of steering column.

About generic fuses, open the driver side door. Remove panel on left side of dash. Fuse box is behind panel:

Hope this helps (remember to rate and comme this free answeer).

the abs light on the dash should come on when the abs is working (emergency braking)if it comes on when braking normally(gently)chances are a sensor is gone(replace in pairs,fronts & rears)
abs stops the wheels from locking up in an emergency brake situation,you will feel the grab-release,grab-release on the brake pedal......

replace the brake switch.i has seen in gm cars if brake switch is open not working.it will cause anti lock brakes stop working.see if anti lock brake module detect fault in brake switch circuit .anti lock brakes stop working.your brake light and abs light will come on.if this dont help.take it to dealership.

The anti-lock light is indicating that your anti-lock brake system has a problem. Check fluid level. Could be a sensor, time for brake service etc, but I wouldn't wait too long to have it checked, just in case something serious. Anti-lock brake problems may cause a wheel or more, or all, to lock up in a panic stop situation. When was last service on brakes done?

check for a defective tail light,or rear socket light,circuit wiring touching each other at trailer plug if equip.usually damaged wiring are at rear of truck,unless wiring mod.were done under dash!
