I think it's fairly safe to say that the worst case per customer FSD retrofit cost is below $1,000:
- Elon said 20 minutes work time, anecdotes said 30 minutes to 3 hours depending on the VIN and model. A conservative assumption would be 2 hours work with $200 cost (labor+overhead).
- Cost of the board is lower than the nVidia board - which I'd estimate at $500 max.
This makes for about $700, which we can conservatively round up to $1,000.
Number of U.S. customers with HW2 FSD is estimated at around 50,000 - so the total worst-case FCF impact should be $50m - potentially much lower, because the service technicians are already employed and can do upgrades from Q1 "idle time", and the board cost might be lower than $500.
FCF should be stronger than this - maybe significantly stronger, so I don't think FSD retrofits will impact Q1 positive cash flow one way or another, unless Tesla decides to smooth the wave and fill inventory in this exact quarter, or there's force majeure.

@EVNow and
@FrankSG might disagree with these very coarse guesses.
