AO service @ 39K

Just a comment that just the other day, I completed my 39 thousand mile service, the indicator on the dash was indicating it as an "AO" service, the service adviser also said that Mercedes recommended a transmission flush which occurs at 39K, so I had the done too.

regards,

Gary

Good. Check how many quarts they invoiced you. If 5 or less, ask them what did they flush, 'cause they only change the carter oil and perhaps the filter. So this left at least 40% that was not changed.

Can you specify what service code "AO" indicate?? I have about 35K on my 2008 C350 and I had “Service AO due in ….miles” pop up. Detailed feedback would be nice. Thanks!
