The work will only use one of the two fuses listed (if they are needed), either $240 or $175, not both.I just got this message yesterday on my 2017 S75D. I opened a service request and got this estimate.

The description is "CUR POWERED" which is short for 'current powered'. In other words no battery needed as it uses the voltage drop produced by the pack current draw across the sensing element to operate.Both fuses listed are "POWERED". My understanding is the new replacement has no batteries.

THANKS!Just received the quote back from Tesla.
They are putting in v2 of the fuse. Total cost, $208.25
I've confirmed the following internally which others have speculated or discovered:
1. The error is timer based which is why all us 2016 owners are seeing this all of the sudden.
2. The fuse is "dumb" so the car can't read the voltage from the pyro battery. Meaning everything could be fine with it, or the internal battery to the fuse could be completely dead. The fuses function is to explosivly disconnect the HV battery in the event the airbags trigger. Kinda cool.
3. The v2.0 replacement is not timer based.
4. Internal documentation confused employees where the word "battery" was mentioned, hence people getting $11k quotes. There wasn't any warning to employees that this error would be on the horizon. Internally, documentation has been updated, hence the more reasonable quotes.
5. Cost should be $113.75 for the part and half a shop hour to do. So total cost may differ slightly by region.
6. Confirmed that after 48hrs with the error, car appears to drive fine. The error message cannot be dismissed. Level 1/2/3 charging still works as expected. That includes supercharging. I'm waiting on service to respond on if there is a hard shutdown timer on the horizon as I'm a considerable distance from my home service center.
7. If you DIY, the car needs to be updated internally that you have the v2.0 pyro. This isn't done automatically and can't be done from any user exposed settings. Toolbox would be needed.
Thank you!The work will only use one of the two fuses listed (if they are needed), either $240 or $175, not both.
No one got a quote for top battery fuse replacement?My fuse must be on top, don't see any access panel.
Still waiting on estimate from Tesla.
What quotes have people getting for the fuse on top?
It's not a failure, it's a calendar time based warning that the battery in the pack mounted HV pyro fuse is reaching the projected end of life. All vehicles with the same manufacturing date for that part in their configuration will raise the error at the same time.
Put another way, all 2017 cars are about 6 years old.
Why do you think NHTSA would care? It's not a safety issue unless it turns out the software estimated current limit is too high and fuses start blowing during normal operation.3/2017 Model S 75D, got the error last week, service got back to me and quoted me $1491.62. Pretty sure I may just wait for NHTSA to force Tesla to fix their crappy fuse. Already got screwed over by preemptively replacing my MCU1 with MCU2 due to eMMC and Tesla refusing to address the issue and then covering it but not offering anything to me because I went to MCU2. Not a happy customer at this point.
Probably because it doesn't have a regular replacement interval and the first replacement is after 5+ years. More like brake pads than filters. Plus, the car alerts the owner when it is needed.If it has a projected end of life, why is it not listed in the service guidelines for the consumers?

My understanding from others is that, as the battery voltage drops, the threshold curent also lowers. So it will still fire if there is a true fault. Unless someone avoids exceeding the trip point and ignores the software reducing power until such time as the battery is well and truly flat...Along the lines of airbags that don't deploy during an accident, the fuse may not blow during an accident.
It’s lame we have to pay for it. But, it’s not worth 200 find out the fuse didn’t deploy
