My 2001 ML 320 is having the ESP/BAS light problem, accompanied by four episodes of the car locking up one of the wheels as though the ESP thinks we're going into a spin (even though we may be driving at 30 mph on a straightaway). I took the car into the dealer, and intially got a computer code indicating a problem with the ABS pump -- which I didn't believe, because that shouldn't make only one wheel lock up. After a week or so, when the problem recurred, I returned to the dealer; and this time the code indicated a bad yaw rate sensor -- which makes more sense to me: if the yaw rate sensor is feeding bad data to the computer, the car thinks it is going into a spin, and engages ESP.
The dealer wants over $1000 to fix the yaw rate sensor ($500 for the part plus labor). I want to DIY, since I read in this forum the part is plug-and-play.
Anyway, in reading old posts on this forum, it appears that the ML 320 has (at least) two kinds of sensors, a lateral acceleration sensor, and a yaw sensor. I have seen the part number 163-542-06-18 posted for the lateral acceleration sensor, but also part number 163-542-23-18 on a different post (an updated sensor?). But I haven't been able to find the part number for the yaw sensor.
Does anyone know what is the correct (and most current) part number for the yaw sensor? When I open up the center consol (I believe the yaw sensor is under the window control switches), will it be obvious which unit is the yaw sensor, and which one is the lateral accelerometer? And how, by the way, do you actually open up the center consol?
Thanks!
