I own a 2010 E350 S and wanted to know whether they have EDR's that support the recording of events like "Turn signal indicators". From the owners manual,l I see that they have data related to the Airbags systems, but nothing mentioned on the turn signal indicators.

Also how do i get the data from the reader. I see one from bosch http://www.cdr-system.com/

Is it the only way to get the data

Thanks,
