I have a 99 SL600 that I think has a faulty body acceleration sensor in the front. First off, the ADS light is intermittent and mostly comes on when it is warm to hot out (I tried reseting the steering angle switch no luck). Second, when I start the car the front end just drops about 3 - 4 inches right off the bat and while driving the front is very bouncy to a point of having to slow down to 25 to keep in the seat. I do not see the accumulators being bad. I did have the codes read on it and of course these came back, body acceleration sensor, steering angle sensor and finally the ride height sensor. Now they all can't be bad, I think one triggered the codes for them all. So before I throw some parts at her what do you think?
