On my Tesla S the original seal lasted 290.000km. Failed in the last year of warranty. The RMN seal (red) failed after 90.000km only. I have done the drains as per your suggestions and installed the triple lip seal now. The surface of the rotor shaft was in a very good condition. I saw the coolant delete kit from QC Charge but for now i hope the seal will work out ok. A big thank you to you for making these videos and your contributions on the open inverter blog too...a must read for all LDU fans.
Fantastic and thanks for the link to the website. My last drive unit was replaced under warranty but I s been over year since then so I need to start checking my drive unit and be preventative on this
What's the feasibility of installing some kind of coolant leak sensor inside the inverter housing, wired into some kind of warning alarm/light? That way you know instantly if there's a leak. Amphol sells one on mouser for $14, designed to detect leaks inside battery packs
Hey man, love your work ❤ is there any way I can add emergency drain on Tesla LDU without pulling the unit? Got a low whirring noise coming from the DU when accelerating, and I am worried about the seal leaking. Gonna check speed sensor today. Going on a long trip in a couple of days.If it is dry, I suppose the issue could be a bearing, but if not I would like to add drain on inverter side before going on our summer vacation drive.
@@diyEVguy Thank you so much :) I have the car on a ramp now and will check soon - the weep hole below the seal seems to be a great idea. Was wondering about that drain plug you put on the inverter side, though; do you have the excact position I would wanna drill? Was thinking by hand, so I don't go too far in. Also, I will add a hose, like you did.
@@diyEVguy Thank you! 🙂 I will do it tomorrow, and post video footage. I'll just try to put it approximately where you put it in your other LDU video (if I discover any moisture on the speed sensor).

You are a gentleman and a scholar. Such an amazing service you provide to the EV early adopter community!
Thank you!
Proper work produces good results!
Nice work Johan and Howard!

Very feasible. See here: czcams.com/video/ps2gha4w5YE/video.html. His name is Vladimir. I have worked with him as shown on my channel and I trust him.

@@diyEVguy Thank you 😊 adding a drain on inverter side will stop condensation? Or do I Also need vents on the top of the inverter cover?

@@fatmanbhkbjorn I did it for the Toyota (czcams.com/video/I_T-djy3TqI/video.html) - I don't know the ideal location for the Tesla...

what if you replace the coolant with a mineral oul, its not conductive.
The G-48 coolant used in Teslas is non conductive.
It seems the search for a good seal is still going on but this ceiming one is good for at least 2k miles?
Correct. See also the longevity page here: sites.google.com/view/teslaldu/longevity
