The sensor arms are about $7/10 at fcpeuro.

I came up to wife's new to us e70 today and the right rear air spring was flat.

It airs right up when turned on the car but already have arnott spring ordered.

Tight budget just spent a ton on new toolboxes and entire rear suspension kit for my car so I'll do her air springs one at a time but will get the other done before a road trip this summer.

Mine are still working at 196k miles! Hers just failed at 76.
