Help!!!! My e39 m5 has thrown this code and has put the engine in safe mode. I can't rev past 3k and also the pedal is dead.I looked up the code, it say the code is P1634 Throttle Valve Adaptation; Spring Test Failed where do I start on a problem like this? Had anyone had the same issue? What was the cost?

That's caused by the throttle actuator motor under the plenum failing a special test that measures the closing time using the spring. It usually requires replacing the actuator. The codes are hex 6B, decimal 107, "Control unit self-test, pre-drive check of drive by wire system". Do a google search at the top of the page using "code 6B throttle test" or similar for more info.
