As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.Google+

Mercedes-Benz SL500 Flush Brake Fluid Every Two Years
Mercedes-Benz SL500 Problem
Average Mileage: 47,333 mi (20,000 mi - 62,000 mi)
Visitor, 2001 Mercedes-Benz SL500, 20,000 mi
I bought 1 2001 SL500 with 18000 miles on it. One problem I had was ABS/ESC light will come on intermittently. Only way to clear it was shut down the car and re start. I flushed the brake system hydraulic fluid once and the problem occurred less often. Flushed it again and the problem went away completely. Make sure you bleed the brake hydraulic fluid at least every two years to avoid this problem, I am doing it now every time I change oil.
