Here is the latest. Apparently the leaking vacuum line caused the pump motor to run to much and over heated. The heat melted the very fragile shaft to rotor plastic piece. The result the pump motor would run but no vacuum or pressure to the systems. Now the problem is finding a new pump without spending over 10% of the car value. Best I have found so far $420. Any ideas where the best prices are for Mercedes parts?
