BAS/ESP ETS ABS Lights On and Noise
My 2002 ML320 is reaching 108K mark, but the BAS/ESP ETS ABS lights comes on only in the morning when I start to drive out. There is a cranking sound that comes from the driver's side in the engine compartment which lasts about two seconds when I drive out, followed by the three indicator lights on: BAS/ESP, ETS, ABS - this will remain illuminated until I stop the car and restart it again, and the issue will disappear. Does anyone know what might be the issue causing this? Please help!!

Hi Sit.
The cranking sound comes at very low speed for a few seconds then it dissapears....That was my steering rack.... The 3 lights abs/bas/esp etc often come on because of the steering angle sensor and they reset at 20km/h. So in my case the damaged steering rack was causing the cranking/grinding sound and the 3 lights to come on

I´ll be sure to keep you guy´s posted if the lights and sound reappear which they haven´t yet (thank God). I have however noticed that after the repair work, where both brake pads and rotors were renewed that the yellow triangle in the speedometer dash starts to flash at speeds roughly above 50 mph and disables the cruise control. Does anyone have an idea what would cause this behavior?
thx.

The caliper is the part were the brake pads sit. It consists of two parts. The main part were the break pads are being held and the cover on the top. The cover is being held in by two bolts. The rotor or the brake disk sits in between the pads. So if your caliper holding the break pads is not properly tight the computer will receive false signals and you will get the EPS triangle warning

Went back to the MB service shop to get a diagnose read out. They claim that the work they did on the brakes is in order and the fault code has something to do with the ABS hydraulic unit. Funny thing though after the visit I´m not seeing the triangle flashing as prior to the visit, however I have noticed that the abs system is jerking the brakes at low speeds?
I think this might be a tough one to chase so any suggestions are really appreciated.
Thx.

I would remove the ABS sensors and give them a nice wipe with spirit. Its a easy job. You will be surprised at all the crap that accumulates on them.
General question: Have you checked your suspension?
1.Ball joints
2.Tie rod ends
3.Steering knuckle
4.Shocks
If your suspension is dodgy the computer will get "wrong" messages.
Remember the triangle? Obviously the dealer "tweaked", "tightened" something they forgot to do on the first place.... Another example of how the computer picks up every small thing.
