no dice

well, had them change the switch, which did not resolve the problem, unfortunately. Surprisingly, the old switch looked nearly as good as the one I bought from Audi...I really had to check to see the slightly higher amount of corrosion on the contacts to convince myself that he had indeed replaced the switch...and am just now literally realizing I should check for the Audi symbol on the part.

Here's some more info I've noted while driving I figure I should share that might help others recognize the issue:

- when driving the car, I will almost consistently get headllight and instrument light dimming and/or radio cutout when I initially step on the brake, and it seems to happen more often when in motion versus stepping on the brake when stopped. I've tested this out a few times and lifted my foot and pressed again a few times in succession. At night it is especially noticeable to see the headlights and instruments dim briefly and come back, or to see them doing their flickering thing in the reflection of the lights on the body of the vehicle in front of me at a light.

-If I have a bit of a slow start where the RPMs drop pretty low, where it seems the car could potentially stall, the lights will dim and the radio will cut out, all of which goes right back to normal once I'm rolling.

-This one I can't confirm entirely, but it seems that sometimes when making small adjustments to the accelerator input that the radio seems to cut out during this. It will sometimes do this as well if I lift off of the accelerator to begin breaking or otherwise slowing down, so somtimes I can get two radio cutouts in a row, one from the lift, the other from stepping on the brake.

-It is any and all lighting in the vehicle, from the dome light to the little door mounted lights, and seems to be only when the engine is running that this occurs, though I'll have to try playing the radio, turning on some lights, and stepping on the brake just running off the battery to see what happens then.

Anyways, he managed to resolve pretty much all my other concerns with the car unrelated to this (I have cold air from my A/C now ), which is great, but my light flickering and radio cutting out are still occuring. And I will say, I don't often drive with the radio or a CD playing, I prefer to listen to my cars when I drive them, but it's kind of annoying when you occasionally do so and have the thing cutting in and out. Can anyone tell me where else I should have him look for a problem? Could it be the alternator? I pretty much have this week and the next to get it resolved while still under the warranty, so I want to try and do so. Thanks again for all the help so far...hopefully I'll be able to get this fixed.
