    I took in my 2017 Model S 75 RWD (19k miles) into the SC this week as I had been noticing a weird humming noise. After two test drives the SC said they'd need to replace the drive unit. On the invoice the replacement part that was used is ASY,P-TRAIN,RMN,MDLS,SPORT,CMC,HS 1025598-00-T. I'm a bit confused that the DU that was installed is of type SPORT since I do not have a performance model. Anyone else had a similar situation? Wondering if they maybe just install the SPORT for simplicity and there is a software limit in place that makes it a non-sport.

    Sport might be standard? It doesn’t say Ludicrous or Insane.

    When looking at other part numbers `BASE` was quite common so I thought that would be the standard part

    RWD cars used the "large" rear drive unit that is also installed in performance models.

    RWD: large rear drive unit
    AWD non-performance: small rear drive unit and small front drive unit
    AWD performance: large rear drive unit and small front drive unit

    Since the RWD isn't made any more and the only application for the big rear unit is in the performance models, I suspect they've changed the part name to reflect that. But it's the same part.

    What is the date of manufacture of your car? 2017 had DU01 option codes added to cars after June 14th. I was always curious if a pre June car would ever get a post June replacement drive unit, whether Tesla would add the option code and whether those cars would be automatically uncorked.

    With a 75 pack that is your limiter not the motor.

    Not in this context. My August 2017 S75 DU01 RWD does 0 to 60 in 4.2 seconds. I assume the OP is more like 5.3 seconds. If they install the large motor, then he should be able to do the faster 0 to 60 time.

    I thought you need an updated pyrofuse in the battery too, which may or may not be present.

    That makes sense, along with software update etc. just clarifying that it is the motor, not battery that is the limiting factor. But, to SSedans point, an S75 can never be faster than mine because of battery size/voltage.

    I've tried to get tesla to tell me if they put a new pyrofuse in my 75kwh pack when they replaced it in 2017 along with the drive unit but they wont provide any info. Any way to tell other than looking at the fuse?

    June 2017 based on my VIN number. Not sure of the exact date or how I'd find out

    I would have assumed it would have been stated on the invoice or work order. Tesla replaced the pryrofuse on our Nov 13 built S85 earlier this year when they replaced the drive unit (bearing noise), HV battery contactors, HVAC drain hose, and 12V battery after we received this series of dash warnings:

    "acceleration and top speed reduced"
    "service needed: car may not restart"
    "regenerative braking system disabled"


    All the replacement parts were listed in the work order and invoice. I'm not sure why they wouldn't tell you one way or the other.

    All the work to my S was done before I purchased it and tesla won't provide me the details other than telling me the drive unit, battery, mcu were replaced in 2017

    They used to tell you the week if you asked, but I am pretty sure nobody will do that anymore. Also no easy way to pull option codes anymore either. June is tough. Could go either way.

    The power difference in DU01 is 30kW but the torque difference is like 100Nm.

    If you ever pull the canbus data off your car during a 0-60 test you can tell what version you have now. Not sure I would bother. It is what it is. Just enjoy it.

    Howell, I am new to the forums and wanted to ask a question about this particular part. I have a 2012 model S signature performance that needs a new Drive unit according to the Seattle service Center. The part number is similar to the part number posted here, ending in T. My question is this: does the drive unit ending in T have the ceramic bearings?

    thanks!
