I would be glad to measure the o-ring, just as I did with the lower radiator hose thermoswitch o-ring as I reported over here...
- Please measure the thermoswitch O-ring size!

If I had the o-ring in hand.

Since I don't have a problem with my DISA valve, and since I don't have the o-ring in hand, I'm hoping someone ELSE will have the o-ring handy (perhaps saved after a DISA valve replacement).

If you have an E39 DISA Valve o-ring - please measure and report back!

Also, it would be interesting to find out what the dimensions of the known DISA valve PN 11617504543 o-rings are.

I find it odd that realoem does not list the size for 11617504543 when I looked just now (at only one model) as shown above.
