No, Tesla and SpaceX sold no Bitcoin in Q3.

Both companies kept holdings unchanged, at a combined 30,221 BTC worth about $2.54 billion, per Cointelegraph at 10:30 UTC Oct. 22 and CoinTalkX.

The split cited in supplied material is Tesla 11,509 BTC and SpaceX 18,712 BTC, totaling 30,221 BTC, described as about 6th among listed-company treasuries.

The $2.54B figure implies roughly $84,000 per BTC. That is a claimed valuation, not a verified trade filing.

I did not find SEC filings in the sources to independently confirm the Q3 balances.
