Mercedes-Benz S430 ABS Modulator Failure Due to Dirty Brake Fluid

(9 reports)

The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.

I have the Elec Stabil as well Brake Bass Assist lights on. I also feel my power steering is not working properly. All these problems started soon after I fixed my Airmatic shocks. I am not sure what the connection is. The car had been driving very well for 6 yrs. -
Brake fluid flush, about $85 at my local repair place. -
