Right under the center console where the driver rests the right arm.
That is what I thought. I know that is where the sensor was on older (‘98-‘01) models. Mine is 2003. I have removed the center console. It is totally different. Sensor is not there. I have found some diogram showing the LA sensor together with Yaw sensor on the same bracket. This diogram also had brake booster on it.
Call up any Mercedes-Benz dealer and give them the vin number for your car. They will be able to look up in EPC where the sensor is located on that car.
You can also look it up yourself on EPC but it costs $75 per year.
Did you find it?
Nope. Dealer would not talk to me about it. Startekinfo was waste of time and money. I had a Mercedes mechanic look at my car. He said that 2003 ml may not even have a LA sensor and everything is controlled by the ABS module. He suggested I replace the ABS module. Just as a background info. My problem started with BAS/ESP, ETC, ABS and Brake lights come on accompanied by seat belt warning beeping. If I stop and put it in Park to shut the engine down and restart, it would lock the shifter in Park. After several tries it would release it and I would continue on my way. When it first started, I was able to reset it by rotating steering wheel from side to side. It worked for week or so. Pretty sure I was looking like an idiot turning my wheel back and forth at the traffic light. However, after a week or so the resetting would not work anymore. My mechanic first has told me that it it was a steering angle sensor. Replaced it with no result. After looking on forums, I have traced it to the lateral acceleration sensor. But now I cannot find it and it may not be the problem.
These symptoms also match a defective brake light switch. At this point I would read the codes and see what fault code you are getting. There is no point on just throwing parts.
Unless you have done that already.
The visiting Mercedes mechanic has done that and as a result identified the ABS module as a problem.
