fuse 22 for the RH side, 5 Amp

XENON LIGHTS I MUST GUESS??U NEED TO HAVE THE CAR TESTED FOR DTCS!!LET ME KNOW HOW U DID !!!

there should have a fuse layout or description in the fuse compartment near or under the light switch.

If you continually blow a fuse when using a high-amperage appliance, you may need to change the rating of the fuse itself...more?------------------------------------------------------------------------------------

The battery in a 2002 Audi A4 is located at the rear of the engine compartment (back near the windshield) & has a tie down requiring a 6mm Allen wrench to remove it.----------------------------------------------------------------------------------------

A 50 AMP fuse is a main power fuse. This is not "isolated" that thing probably feeds 5 or more other circuits. You need to get the power distribution diagrams and narrow it down further by pulling the fuses (NOT RELAYS) that are fed by that fuse. Once you have it narrowed down to a single (small) fuse, then you narrow it further by checking the circuits that are fed by that fuse. You must check everything that is fed by the small fuse. The easiest way is using the power distribution diagrams to unplug all of the components (one at a time) that are powered by that fuse. Sometimes you can eliminate two or three components at a time by disconnecting a single, common connector.

No recall situation as far as I can tell (get 2nd, 3rd opinion).

Try this first. Instead of using the standard amp fuse, raise it up by 10 amps. So if it uses a 20 amp, use a 30 amp fuse and see if it still blows. If so, it sounds like you have a loose wire, or a ground issue. Something is shorting them out.

Also, consider replacing the switch under the brake pedal that actuates the brake lights to begin with. This could have been the problem from the start.

And a Tip: NEVER pay someone that much just to "look" at anything this small.

This is an easy fix, we just need to find the source of the problem, and for something like this, there aren't many places the problem could be.

Rest assured, we'll get it.

You could have a problem with the xenon light itself on the passenger side or the wiring running to the light assembly.You could unplug the connector from the light assembly and replace the fuse if it still blows the fuse, its in the wiring harness if it doesn't it problably is in the light assembly. I'm not sure how the lights are configured on the Z if the zenon lamp is replaceable by itself, you can try swapping it out. I haven't had any problems with my Z but those are a few suggestions on troubleshooting your problem.
