| I'll add my thanks for all of your work in the videos, and will be very interested in how well your repair holds up over time.
The purpose of the mastic is not to "seal" - it is to dampen vibrations that may cause the brass valve to crack (especially where it passes through the seal). The earlier S-Classes did not have the mastic at all.
Regarding mj23cg69's question, the Airmatic relay will have a Siemens name if it is the older style, and Hella if it is new. If you have a Siemens relay, it could still have been replaced, but it would have been the same problematic kind as before.
