Was bedeutet der Fehlercode?

The hydraulic pump is activated but the supply voltage to it is too low, and the fault code is set. The cause can be a weak voltage supply, an open circuit in the supply lead to the pump, a blown fuse for the pump, or an internal fault in the convertible roof module (CRM). The roof may then operate to a limited extent or not at all.

Mögliche Ursachen

Supply voltage too low
Open circuit in the voltage supply lead to the hydraulic pump
The hydraulic pump fuse is blown
Internal fault in the roof control module (CRM)

Was Sie tun können

1Check that the battery is charged and that the terminals are tight
2Check the hydraulic system fuse in the engine bay fuse box, and replace it if it is blown
3Inspect where the hydraulic pump connects to the roof control module for oxidation and loose contacts
4If the fault remains after these checks, a workshop should look at the roof control module
