I purchased a 1999 E320 in April 2003. It had 43,000 miles on it, now it has 50,000. After reading this post, I went back and reviewed again the maintenance records, and saw that this car was towed to the shop June 2002 at 36,565 miles because of this HB issue.

It was repaired under warranty. The repair invoice states that the engine was removed, replace upper and lower oil pans, front engine timing cover, oil level sensor, serp belt and HB. It looks like they recorded 17 hours worth of work. WOW!

Although this was repaired prior to my ownership, I want to support those who are experiencing this issue. Does it help for me to log this repair as well, even though I personally didn't experience it?

Do I need to be concern with this happening again?
