Brake Issue
I have a 2002 ML320 and have recently been experiencing the intermittent BAS/ESP/ETS warning light problems. I've not yet replaced the stop switch as has been recommended elsewhere. Today, a new dimension was added to the mix in that my ESP control unit assembly started making some odd noises. It seems like the motor/pump(?) around the control unit is running constantly and producing the sound. In fact, this motor/pump(?) around the ESP control unit continued running with the ignition off for over an hour until I disconnected the battery to stop it.
Anyone have any clue what the issue may be?
Thanks.

More on brake issue
After disconnecting and reconnecting the battery, the warning lights remained off and the ESP unit wasn't making the noise anymore.
It seems like a lot of folks go to their auto repair shop and end up replacing many different brake system components just to find the fault lies in one particular area later on. I'd like to avoid this if at all possible.

Wow, the dealer says my car needs a new stop switch and ABS pump at the astounding cost $2500. With only 75k miles on my ML, I have to say I find this pretty ridiculous. For the $45,000 I spent on my car, I expect to make it to 100k without any serious issues.
I really have to question whether I want to buy another Mercedes in the future.

Try just the brake switch and see if it corrects the problem. What most likely happened was that you did not have the issue taken care of ASAP and the ABS pump was running all the time and burned itself up due to overheat. Unfortunatly a 45K car today is not a lot of money. Having to spend 2500 for the repair is also not much money after all those years of ownership. However I can understand your annoyance but to say you will never own an MB again is rediculous. Perhaps you will not have this exact issue with others but there will be similar expendatures that will be required.

Sorry to hear your having problems.
Though for real, you gotta do a cost analysis here. $2500 for basically a new brake system sounds about right. But hey if your spending the money matybe you can upgrade to some stronger brakes. Also have you priced it out yourself? The dealer is notoriously high for labor and parts.
Not trying to belittle your dilemma but don't feel like the dealer has a gun to your head for $2500. Personally I'd check some local shops to see what the cost breakdown would be.

They replaced two things:
1) the brake switch
2) the abs control until (said to be $1600 part)
I whined a little bit and got them down to $1950.
It sure beats buying a new benz, but it still sucks having to drop that kind of cash on my ML. Hopefully, I'm not going to run into these sorts of repairs often.
I actually think this problem started before I was even out of warranty since those lights came on pretty much from day one of ownership. But they didn't come on often and I didn't make a fuss over it with the dealer. In retrospect, I should have had them look at it in more detail.
I did try taking the car to a local benz shop, but they said it needed to be taken to the dealer once I mentioned the ABS unit.

Try this link, I just fixed mine using this procedure. It had a bad solder joint on the circuit board on the pump. Took about three a hours to fix, well worth the effort.
