You may need to try another SC if yours won’t replace the FDU for this issue. Try talking to the service manager if possible and reference the same issue happening to many early FDU’s in this post. Mine was also A LOT louder in the winter.
see my last post:
“To get the parts info go into service mode/High Voltage ⚡/Drive Unit, Press the Green FDU or RDU on the display/Parts info/Run, follow the instructions to press the R turn signal & Brake pedal.” Bladabing
My ‘24 Beast vin 34xxx, My wife’s ‘26 AWD vin is 87xxx.
Just had the ‘24 Beast FDU replaced with new 1920000-T1-L which fixed the bearing noises at zero throttle. The ‘26 AWD has the 1930000-TX-G FDU and the RDU has the 1920000-TX-M.
To get the parts info go into service mode/High Voltage ⚡...
They will inspect the halfshafts for damage/wear when they replace the bolts for that SB. The fact that you hear the noise when it’s cold more tells me it’s probably the FDU though.
Seems about the same with 14.3.3, but sometimes doesn’t do it so much, but overall better IMO than previous software versions. Only had 14.3.3 for several days now though.
Main reason for the service visit was to replace the failed PCS, then several other issues I had been holding off on since the SC is more than 2 hrs drive. I was happily surprised they took care of the FDU rattle as well. Great SC to deal with.
Update on my Beast: Tesla replaced the FDU to the latest FDU rev L and I can confirm the bad bearing, flutter, crackling noises are gone, plus it’s much quieter overall. South County St Louis Tesla did a GREAT JOB!
New Update: I can confirm after driving with the new FDU the last several days...
Update, bit the bullet and drive to the nearest SuperCharger and it works.
Coincidentally, while supercharging I received a call from Tesla stating that I had received the update to enable supercharging. Thrilled to be able to use my truck till SC appt and the threat of having to tow gone now...
