I tried this question in the Crankshaft Balancer Failure thread but with no response. So I am trying here to see if someone can help me.

Please help!!! My balancer # does not match any of the ones mentioned in the thread.

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 there is a little space and then also reads 12 01. Could someone please let me know if this is an updated part or one of the original problematic ones? Thank you.

The 113-035-01-00 is the correct replacement number.

The original(bad) numbers were "WA"-113-035-01-00 OR 113-035-00-00

Thank you for your response, I appreciate it, but I am also a little confused. How can 113-035-01-00 be the correct replacement number and also be one of the original (bad) numbers??

Mercedes number 113-035-01-00 VS WA-113-035-01-00 is the difference. See the original number had a WA prefix!!!

A part number with a WA prefix indicates a "special" part for AMG cars only!!
