92 300te 4 matic light ?
 

The 4 matic light on my wagon keeps coming on. The first two times i took it in to the shop,they said they checked for codes but none where found.and reset the system.I have reset the light the next three times my self by disconnecting the battery.The first two times the light came on i was going slowly in a parking lot turning to the right, pavement dry. 3rd time while putting the car into park. 4th when aeccelerating from a stop. The 4 matic system has come on once while going over rail road tracks. but didn't pop the light on, i've only owned the car sence 9/03. after resseting the light i can drive the car around 100 to 150 mile before it just comes on again???

thanks for any help or info
