Can’t you get any of that from the service webpage? Most likely not, but it’s worth a shot.If anyone has an 21+ M3 (w/heat pump)HVIL (high voltage interlock loop) diagram and ohm specs I sure would be happy .Still trying to figure out where i have a HV problem on my paperweight., thx
No I wish. They keep all the higher diagnostic info hidden even if you purchased the toolbox 3 software. They are supposed to give you the battery shipping tool(they don't) and tech articals on tech issues in that same software but they hide them so they are inaccessible unless you can backdoor a way to find it which is a needle in a haystack. Pretty crappy really.Can’t you get any of that from the service webpage? Most likely not, but it’s worth a shot.
Dude you rock. Thank youI found this, rummaging through my old files, but this is for a Model 3 w/o heat pump. I’ll see if I can send you the whole thing.

BCH said they aren't willing to share their source for triple-lip seals, in fear of running out or buying them all and jacking up the price.
They rebuild enough of them that they have 2 extra cleaned stators on the shelf to reduce rebuild time by eliminating the need to wait for shipping both ways on the stators.
howardc64 has an extensive write-up on seal types and sources at Tesla LDU - Parts
There's also testing of different seals going on by DIY'ers at Tesla Large Drive Unit (LDU) Motor Teardown and maintenance - Page 11 - openinverter forum
I asked about warranty and I'll update when BCH responds.
I find it hard to believe there is no SKF equivalent that can be ordered locally. I used to repair servo motors and we would just measure it, get the specs, and call a supplier and order what we needed. What is so special about this seal that it has to come from Ukrainian?I believe all tan color triple lip PTFE seals I’ve ever seen from ukrain rebuilder/seller and QC Charge are all Ceimin from AliExpress. I have in hand and every single seal detail is identical. Ukraine guys even laser itch Tesla logo on them.
There is also the other half of the equation which is shaft surface condition. Likely poorer surface on the reman LDUs etc. I made a flow chart for decisions and seal sourcing and longevity data. All on the above linked website.

EDIT:
I just read the info at the LDU forum links. Excellent information and great research! Thanx
Hi all, I do have exactly the same situation with my restored m3, just can not get rid of RCM_a114. Would be appreciated if someone could help me with that code.I have just rebuilt a 2019 model 3 performance and have just powered the car up for the first time since the repair.
it was a front collision car with driver and passenger airbags, curtains and seatbelts deployed. all airbags were replaced for new ones and I sent my RCM to Ingineer to be reset.
once I put the car in drive the airbag light comes on and I get these 3 errors, RCM_a114, RCM_a013, and RCM_a004. does anyone know what these refer to as I am really unsure what the problem could be now!
Hey guys! Quick question, Does Tesla disable autopilot on blacklisted cars that don’t have supercharging and if so, is it possible to get it back?
yes Tesla does it they remove from salvage car supercharger and FSD.
This is your car you have always had that was totaled and FSD disappeared?FSD hardware and software is there of course and work with autopilot but summon and beta disappeared. and it was there before.
And it wasn't on a FSD trial or subscription? (Or a vehicle that someone had taken advantage of Tesla's FSD transfer promotion on?)FSD hardware and software is there of course and work with autopilot but summon and beta disappeared. and it was there before.
yesThere's another pyro fuse next to the 12v is it possible that is what is keeping this from charging and driving?
