So far none of these could make the ABS ESP and ETS light to turn off. I wonder if these warning lights need to be reset somehow if one of the above issue could have resolved the issue. If so, how to reset the warning. 
Thanks in advance for your advice,

Go to the top of the ML forum and click on search, type in ABS pump and look for my solution to this problem. You can use the same troubleshooting procedure that I did, even if the problem lies elsewhere. The dealers are very quick to replace the ABS pump assy and they blame the leaking window washer tank for shorting this out! NOT likely! The lights will clear themselves if you have eliminated the problem.
