Rolna 29A, 62-081 Baranowo near Poznań Mon-Fri 9:00-18:00 5,0 on Google · 14 reviews
We repair Tesla electronics: black screen and reboot loop (eMMC memory replacement, MCU1 Tegra repair), MCU1 to MCU2 upgrade (Intel Atom), Autopilot camera and radar errors, and cloning control unit configuration. We diagnose the module on the bench, outside the car, and replace chips by BGA micro-soldering. Estimated prices: fault diagnostics 400 - 700 PLN, eMMC / MCU1 1 500 - 5 000 PLN, MCU1 → MCU2 5 000 - 8 000 PLN, camera and radar calibration 800 - 1 200 PLN - Poznex, an independent Tesla service in Baranowo near Poznań, phone +48 662 189 700.
Specialist repair of on-board computers, integrated circuits and modules.
We fix black screen faults (MCU Tegra/Intel), replace eMMC memory and carry out hardware conversions of Autopilot computers.
- eMMC memory replacement in MCU computers
- Module data cloning
- MCU1 → MCU2 upgrade (Intel Atom)
Typical electronic faults
Display problems (MCU)
- Reboot loop, endless Tesla logo (eMMC fault)
- No communication, no sound, black centre screen
- Stains and bubbles on the centre screen (gel leak in Model S/X)
Control units and Autopilot
- Driver assistance unavailable, side and B-pillar camera errors
- No communication with the radar / radar_a errors
- Cloning the configuration when replacing control units with used ones
How is the electronics repair done?
- 1. Bench diagnostics. Removing the module and connecting it to a dedicated programmer.
- 2. BGA micro-soldering. Replacing memory chips / integrated circuits using an IR/hot-air station.
- 3. Programming. Restoring the encryption keys and system calibration in the car.

Frequently asked questions
Black screen or an endless Tesla logo - does the whole MCU computer need replacing?
Not always. A reboot loop and an endless Tesla logo are often caused by worn eMMC memory. We remove the module, diagnose it on the bench, replace the memory by BGA soldering, then restore the encryption keys and calibrate the system in the car. An estimated 1 500 - 5 000 PLN; we confirm the exact cost after diagnostics.
Is an MCU1 to MCU2 upgrade worth it?
We replace MCU1 with MCU2 (Intel Atom) - an estimated 5 000 - 8 000 PLN. Whether repairing MCU1 or upgrading is better for your car, we will advise after diagnostics - call +48 662 189 700.
Autopilot is unavailable, with camera or radar errors - what do you do?
We check communication with the side cameras, B-pillar cameras and the radar (including radar_a errors) and, after the repair, calibrate the Autopilot cameras and radars - an estimated 800 - 1 200 PLN. If we replace a control unit with a used one, we clone its configuration.
How much do diagnostics cost and how long does an electronics repair take?
Advanced diagnostics of an electronic fault cost an estimated 400 - 700 PLN. The repair time depends on the module. We keep turnaround times short - we confirm the exact time after diagnostics, together with the price.
