One problem related to warning light on has been reported for the 2003 Mercedes Benz E320. The most recently reported issues are listed below.
While traveling on i94 thru north dakota my srs warning light came on. A message on the dash board told me to visit a repair shop as soon as possible. About 10 minutes later the light went out. The light came on again while slowing to exit the interstate highway for a fuel stop. Upon restarting the engine everything was normal. About 30 minutes later the srs light came on again for about 5 or ten minutes. This pattern of normal engine starts and then intermittent srs warnings continues. I have read in the Mercedes Benz owners forum that there has been an NHTSA investigation : pe10017 that appears to reflect the same problem I am having. Please help.
