I pulled my speed sensor for the first time. Guess it looks as expected. That flyover tube is going to be a real problem to remove.
Not sure you have coolant yet from those pics. EVERY SINGLE first speed sensor pull on LDU from Tesla looks like this (also confirmed with @ajbessinger at QCC) I believe Tesla is greasing the seal on install. All PTFE seal literature says to keep it clean on install but I'm guessing grease will just burn off the lip contact surface quickly. Tesla maybe greasing it for installation. Triple lip seal with excluder lip require experience and procedure to install properly without folding. Even single lip seal probably require quite a bit of force over the chamfer on the rotor shaft opening as PTFE seal lip (feels like hard plastic) is more than 2mm smaller than shaft diameter. Cutting PTFE seal lip will cause instant leak.
I think the spun off grease is what you see on yours so perhaps still very early stage to no leak yet stage.
Have also heard/seen some early S's able to get 100k+ miles and 8+ years without a leak. My guess is the grease on triple lip seal with its 2 in betwen lip chambers might have something to do with it. But no proof or careful study of course.
BTW, what is really strange is ALL seal of any type and any design leak some minute amount (eal designers work towards such specs. Doesn't make sense LDU seals don't leak even a little even if working as designed and we are talking about much thinner viscosity than oil. But its a sealed environment so not really sure where the leak went. Perhaps we are just not seeing an LDU opened up without chasing a leak to see its internal condition "before" noticeable leak.
