I just got my CPO 2008 E350 with 33K mile in Feb 2011, It ran fine but had the CEL on and off by itself, I took it back to dealer and they told me that the balance shaft needed to be replaced (under warranty). My engine serial# is "272964 30 784919" which is greater than "2729..30 468993" listed in S-B-03.30/08i, is It possible?
Thanks,
