"BAS/ESP" & "ETS" lamps

“BAS/ESP” lamp and “ETS” lamp remain illuminated after the power steering fluid “leakage” was fixed by changing all power steering hoses.

My lights light up occasionally also. I have had my ML320 tested and the computer isn't reading any trouble codes. I was told to swing by the dealership the next time they come on, but my schedule prevents me from doing so.

I have replaced 3 different switches this year and am not looking forward to replacing any more.

Let me know if you find out what the problem is.

My ML is doing the same thing. I was finally able to throw a code and it came back as:

Inlet Manifold Temp Sensor.

I do not know if this is related but I might start there. This part is about $400

I will try that in the morning.

Did you hear any sounds from perhaps your ABS pump?

Thanks
