SL55/63/65/R230 AMG: SBC warranty extended to 25 years
I made an appointment and dropped the car off at Mercedes of Downtown Los Angeles on 08/31/2018. They loaned me a courtesy vehicle through the long weekend even though I offered to bring the car back on Tuesday since they don't service these type of repairs on Fridays/weekends and Monday was a holiday. I got a text on Tuesday saying the car was ready to be picked and I picked it up on Wednesday. The service tech said all that was necessary was a software reflash to remedy the issue. My friend with a similar vehicle (E320 CDI) had a red message on the dash and his vehicle is having the accumulator replaced.

DasGeld, I think I saw you ask about timing on about when the service threshold might trip. Mine hit at about 95,000 miles.
