2008 MB S600 abs and eps inoperative

It could or could have electric power sterring , look up under the dash below the steering wheel an see if it has a electric motor on the steering column .
Power Steering System Description and Operation (with EPS)
The Electric Power Steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the power steering control module (PSCM), torque sensor, power steering motor rotational sensor, power steering motor, discrete battery voltage supply circuit, and the GMLAN serial data circuit to perform the system functions. The PSCM and power steering motor are each serviced separately from the steering column assembly. However, the motor rotational sensor is serviced as part of the power steering motor, and the torque sensor is serviced as part of the steering column assembly. The PSCM also monitors vehicle speed from the engine control module (ECM) via the GMLAN serial data circuit. At low speeds more assist is provided for easy turning during parking maneuvers. At higher speeds less assist is provided for improved road feel and directional stability.

Your vehicle has electric power steering . GM had a recall on some of it's vehicle .
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, nor the EPS motor are serviced separately from each other or from the steering column. Ant EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

Sounds like you are losing wheel speed signal when under hard turns. This is commonly caused by the harness at or near the wheel speed sensor has a bad connection of there may be a break in the wiring that intermittently loses signal to the ABS module and causes the anti-lock function to happen, (loss of wheel speed is like wheel skid as far as the ABS module is concerned) It is usually necessary to have a scan tool to monitor the data and read codes on the ABS system. You may have to take vehicle to shop that is capable of diagnosing the problem.

DIYer? There is probably a "reset" in the computer system when pads are changed. It may be an MB trade secret for the prevention of liability issues.

Well. I don't think they will be related. EPS is your electric power steering light. The hub would have the ABS system attached to it. Have it hooked up to a computer at a parts store for free and they will tell you the code that is tripping the light and what it is.

electri power steering assits is bad.. needs looked at...the motor that helps turn the wheels is not working..

It is safe to drive. You need a scan tool to get a code out of it. Could be as simple as a wheel speed sensor going bad. All of these lights will work together normally. The traction control uses the ABS to gain traction, and the Brake Assist System is part of the stability control. Also uses the ABS.

Hi. Thanks for your question. For assizstance on EPS light in 2008 ML 350 You can visit https://www.reliable-store.com and download the entire workshop manual which includes all the information along with the diagrams which will help you in checking lights. Good day!

EPS

EPS: Electronic Power Steering - enables the amount of assistance with steering to be varied depending on speed and how much you turn the wheel. This means it can give lots of boost when parking the car whilst still giving you a good feel for the road at speed.

It was the ABS system kicking in to try to keep the wheels from locking up. The squealing you heard was indeed the tires "sliding" across the surface in protest/resistance to your turning input thru the steering wheel. If you are not comfortable with that feeling go ahead and take it to the dealer/repair shop and have the ABS system checked/tested. (preferably the dealership)
