Please help!!! My balancer # does not match any I have seen in these threads.

I have a 2000 E55, manufactured in 12/99. M113 engine. The part # on my balancer is different than any I have seen on these threads. It is 113 035 01 00 12 01. Could someone please let me know if this is an updated part or one of the original problematic ones? Thank you.
