At roughly 80,000 miles, began receiving abs and esp warning lights, intermittently at first and then increaing in frequency, so that now they are on roughly half the time. Mechanic diagnosed abs control module fault code c1120 ("standstill calibration of yaw rate sensor erroneous") and confirms that I am without abs when warning lights are on. Mecedesbenz technical service bulletin number af42. 45-u-8103a (dated 22 Jun 2000) indicates that this defective abs control module part was replaced in production starting in 2000, and was replaced in field as a recall item for some period of time thereafter, on report from regional technical coordinator. My attempt to have mbusa replace this part (cost approx. $1100) has been refused. Attempting to have part covered by aftermarket warranty company as well but a significant safety defect is still present in this vehicle and I believe that mbusa should replace control module.
I was doing around 55 and the road was curving slightly when I suddenly saw a large object in the middle of the road. I could not go to the other lane because a car was right next to me so I slammed on the brakes, I felt abs kicking in and was finally able to go around the object which turned out to be a large cardboard box. At this point is where I encounter my problem, I give the car gas to proceed down the road, the car just revs as if it was in neutral, I look down at my shifter and it is in d. I shift down to lower gears and nothing. Now I'm nervous because I see cars coming to my rear and there is no emergency lane on this road. After 30 seconds of no connection between engine and trans, the trans finally engages and I am able to proceed.
