2001 ML320 BAS/ESP, ETS,ABS, brake warning, check engine signs all on!
Someone with same experience please help me!
My 2001 ML320 had check engine light for months which I ignored.
2 months and 2000 miles ago I had front brake pads and rotors replaced at a shop (OEM ones).
Since 1 month ago occasionally in the morning when it's chilly here in San Diego, BAS/ESP,ETS,ABS,Brake warning sign and red Brake sign illuminate all at once with beeping sound upon ignition or 5-10 seconds after ignition. Car shakes upon gear change. When I drive on, speedometer stays at 0, although tacometer works and the car feels like scratching on the ground with increased friction, as if I had not released the brake.
This is not happening when I start the car later in the day when it's warmer. The next morning it recurs.
As you might have noticed, I am a novice. Someone said it's brake switch. others said it's speed sensor. Stealership said ESP control unit, traction unit. They said ESP control unit is faulting and ESP control unit connector has corrosion, quote for replacement is $3319.
I know similar problems were posted here many, many times but wondering if someone had exactly same problem I have and can share how they handled it. Thanks!
