Signs
- Inverter / oil pump errors, power drop or rear drive shutdown.
- Most often on 2017–2019 builds; the 980 motor itself was fitted until roughly 2022–2023.
Solution
- Replace/repair the inverter, check cooling.
- Reflash/initialize per the Toolbox procedure (see manual).
Belarus budget
≈ $1 000–2 000 for inverter repair / related work (without replacing the entire DU).
