Is re-timing needed after VANOS seals ?

Quick question.
I have an 2001 E39 525. I'm about to re-seal the VANOS unit. I'm hearing some people have had timing issues post VANOS re-seal. Posts don't say why they had timing issues, is this something I can avoid.

All I'm doing is removing the VANOS unit, replacing the seals and re-installing.

No, retiming on the M54 engine is not required following removal of the Vanos. Just follow the Beisan procedure and you are all set.
