Check the pump hydraulic reservoir level behind the boot carpet first, it could be low after the long winter months. Check here...





Probably could do with a yearly top-up!

01089 is the roof hoop stowed switch F204, the codes you have are saying that the roof ECU is receiving an implausible signal.

The possible causes are:-

- Contact corrosion in connector
- Open circuit in wiring or short to positive

Possible effects:-

Convertible top can be moved in normal manner; at end of closing process convertible top drops onto roof frame.

Other cause:-

Switch not switched within specified time limit

a) Insufficient hydraulic pump operating voltage (min 9v).
b) Convertible top stiff.
c) Solenoid valve 6 -N93 not functioning or mechanical fault in valve.
d) Insufficient pressure in hydraulic system:
- Hydraulic pipes to frame cylinders kinked or leaking.
- Internal leak in frame cylinder.

Possible effects:-

Convertible top can be moved in normal manner; at end of closing process convertible top drops onto roof frame.
Closing is not commenced.

This might help:-

Hydraulic system
Filling and venting hydraulic system
Notes:

◆ The electrohydraulic convertible top actuator mechanism is a closed hydraulic system, which generally only has to be filled after opening hydraulic circuit (e.g. following component replacement).
◆ On account of the stroke and displacement effect of the pistons in the hydraulic cylinders, the hydraulic system must be filled with the convertible top stowed in its compartment.

Bleeding

Note:

The hydraulic system is self-venting. Opening and closing the convertible top several times vents the system.

‒ Start engine.
‒ Close and open convertible top 4 ... 5 times using electrohydraulic actuator mechanism.
‒ Convertible top must move evenly and smoothly



‒ → Check fluid level in reservoir -2- with convertible top stowed in compartment.
‒ Fluid level must be between MIN and MAX marks
‒ Top up hydraulic fluid if necessary.

Check for damaged connector pins on ECU? There are ususally many cabriolets being broken on eBay UK for a used ECU.
