2000 ml320 has,in the past two months,started to light the first three warning lights on the left of the dash(ETS/ESP/ABS)at the same time when the car is first driven in the morning.This is accompanied by a groan(moan)for a second or two.This happens within the first 200 feet of leaving my driveway without touching the brakes.If I shut the car off and restart it will usually go away but this also is not always consistent.Car does not do this every morning,and occasionally it will do it after use for several hours,then not for days.I have lived with this as an annoyance.Today it did not light in the morning or during use for a half dozen stop and go errands.I stopped the car for about five minutes and when I restarted and drove off,the lights came on accompanied by a long(10 secs.)groan(moan) and an audible hissing sound.Now the groan happens every time AFTER I step on the brakes,and lasts about 7 to 10 seconds.The groan is so loud that people look at the car.The hissing is in the area of the front left wheel and sounds like a leaking air hose.The hissing does not stop when the car is shut off but continues for about a half hour then stops.It sounds like an air compressor is running.I intend to get under tommorrow morning to look at front left area.If anyone has had this exact problem I would be grateful for your input.Anything to keep me out of the dealers shop !!!
