It looks like there is no part number for the M54 engine in Realoem.
But that doesn't mean there isn't a similar part that BMW sells that we just don't know the cross reference to.

For example, the #4 o-ring below is an exact replacement for the lower radiator hose thermoswitch o-ring (which itself doesn't have a part number).

Maybe we can find a similar o-ring in the BMW catalogue for this DISA valve (aka #7 Adjuster Unit).

Does anyone know the size of this DISA Adjuster Valve o-ring?

Here is the link on realoem for my M54 engine.

Realoem clearly lists two different o-rings:
# Description Supplement Qty From Up To Part Number Price Notes
04 O-ring 8X3 1 13621743299 $1.25
06 O-ring 7X3 6 11617502761 $0.88

But neither o-ring is for the DISA valve, per se:
# Description Supplement Qty From Up To Part Number Price Notes
07 Adjuster unit 1 11617544806 $212.50

Here is the complete listing from Realoem.
