To get at a leaking oil feed on the turbo ( Polestar T6) I need to remove the "firewall" behind the engine, which is bolted to the bodyshell. To do that, I'll need to disconnect the harness from the ECU, which is behind that "firewall". There seems to be no way to remove the ECU with wiring connected.

Does anyone know for sure whether doing that will generate an error situation, necessitating a visit to the Volvo dealer to get it reset ?
