I distinctly think it was introduced in 2002MY

I have to find the PDF for this but in my air susp troubles I used to refer to the BMW tech manual for EHC systems, and it distinctly referred to the all new EHC2 system being introduced, and I feel like it was a 2002 manual. I think Arnott only uses 2000-2006 on their website because those are E53 model years.

Regardless its neither here nor there but I have never seen a 2000 or 2001 with full air. Maybe Qsilver or someone with the wealth of knowledge could find the EHC2 guide as to which year it was introduced?
