CCS2 Fast Charging on an Imported Tesla — What Actually Needs to Be Done

You plug into a European fast charger and nothing happens. The car just sits there. If you've imported a Tesla Model 3, Model Y, or Model X from North America, this is probably the first frustrating wall you've hit.

It's fixable — but it's not an adapter problem. It's hardware.

Why It Doesn't Work

North American Teslas have a different charge port ECU — the small module that manages the charging session. The NA-spec version doesn't have the CCS communication chip that European fast chargers require. A CCS2 adapter physically fits, but the car can't talk to the charger. No handshake, no charge.

Which Part Do You Need?

For Model 3 / Model Y (2019–2022) — you're looking for the Gen4 Charge Port ECU:

Part Number	Notes
1537264-00-B	Original CCS-capable variant
1537264-01-B	Revised version, same function
1537264-20-B	EU export — confirmed working ✅

⚠️ The -80-B suffix is the stripped NA version — the one that's probably already in your car. Don't buy another one.

For Model X / Model S — different assembly, different part:

Part Number	Notes
P1495114-00-C	Confirmed working on 2019 Model X ✅

What the Job Involves

The ECU is inside the charge port assembly, accessed through the rear quarter panel. On top of the physical swap, a software reinstall from service mode is mandatory afterwards — this re-flashes the firmware onto the new module. Without it, the new ECU won't activate correctly even if the hardware is installed perfectly.

After the reinstall you can verify it worked at Controls → Software → Additional Vehicle Information — the CCS Adapter Support field should read "Enabled".

⚠️ Pre-October 2020 Model 3 (chrome trim era) also needs an extra wiring harness adapter due to a different port generation — worth flagging before sourcing parts.

The Adapter

Once the ECU is sorted, you need a CCS2-to-NACS adapter to physically plug into European chargers. Tesla sells one in some EU markets; third-party options work fine too. Just make sure it says CCS2 / Combo 2 and is listed as compatible with Tesla.
