I have a 78 Audi 5000 that I have had for about a month now. On two occasions now (both when it was raining), my Cruise Control warning light has come on. When I turn the vehicle off it stays on and will kill the battery if I don't disconnect the battery. When the Warning light is on anytime I step on the brakes the warning light turns off, and will do so whether the car is running or not.
I have gone through the owner's manual and understand that the warning light has to do with the throttle linkage being stuck or something to that effect? And have looked for information about this and it would seem that Audi had some problems with this during this era; however, the car isn't sticking at all. The throttle works just fine, and the Cruise Control also works just fine when the light isn't on. I have not had any other problems with it at all.
What could the problem be? And if no ideas, how can I turn the light off without disconnecting my battery? I have to wait til the car dries for it to turn itself off.
Thanks for any help you can offer.

P.S. Any tips for finding a leak in the power steering system would also be appreciated.
