MCU1
Tegra
2012–early 2018. Slow maps. Many owners retrofit MCU2.
Buyer’s guide
SC01, hardware, MCU, and the drive unit. Sellers often mix these up.
5-minute HW4 inspect
Parking-lot cameras, then the software screen.
SC01 buyer checklist
Who can have it, what strips it, how to confirm.
SC01
Unlimited Supercharging that can follow the VIN.
SC codes
SC01 vs SC05 vs promo. Only one transfers.
How to verify
App, Tesla Support, option list.
MCU versions
Tegra vs Intel vs Ryzen. The screen you live with.
LDU issues
Early Model S rear drive units.
Autopilot hardware
HW2 → HW4 / AI4.
SC01 is rare and expensive when real. Use this list before you pay a premium. VIN alone cannot prove the option code.
Model gate
Only early Model S and Model X. Model 3, Model Y, and Cybertruck never received transferable SC01.
Order date
Almost only cars ordered before 15 January 2017 (deliveries roughly through April 2017). A 2017 build is not enough.
CPO / buyback / inventory
Tesla CPO, buyback, and some auction cars can have the entitlement stripped even when the year looks right. Ask directly.
App screenshot
Seller screenshot of Free Unlimited Supercharging. Ask them to confirm it is not first-owner promo / SC05.
Tesla Support
Have Tesla confirm SC01 on that VIN. Option list should say SC01, not SC05.
Road-trip value
Free Supercharging only reliably works at Tesla-owned stalls. Filter the charging map. Many SfB sites will charge you anyway.
Price the premium last
A working LDU, MCU, and title matter more. Do not pay an SC01 premium on a guess.
Option code for unlimited Supercharging bound to the vehicle. Almost only on Model S and Model X ordered before 15 January 2017 (deliveries roughly through April 2017). Tesla CPO and buybacks can strip it.
| Code | Meaning | Transfers |
|---|---|---|
| SC01 | Unlimited, vehicle-bound | Private sale |
| SC05 | Unlimited for current owner | No |
| Promo / SC06 | Time-boxed credits | No |
MCU1
2012–early 2018. Slow maps. Many owners retrofit MCU2.
MCU2
Late 2018+. Usable. Still not Ryzen.
MCU3
S/X refresh, Highland 3, newer Y. The one you want if you live in the screen.
Early rear-wheel-drive Model S cars used a Large Drive Unit that can fail (bearing / seal). Budget a specialist inspection on 2012–2016 RWD S. A cheap SC01 car with a tired LDU is not cheap.
HW2 / 2.5 cannot run current FSD Supervised. HW3 runs v14 Lite on 3/Y. HW4 / AI4 runs full v14. Full compare
