General information on hydraulic system

The hydraulic system is self-bleeding and maintenance-free.

When the hydraulic cylinder or hoses are replaced, no topping up the hydraulic fluid is necessary. The system contains sufficient hydraulic fluid so that the fluid level does not fall to or below the min. mark.

When operations are performed owing to loss of hydraulic fluid, the fluid level must be checked and rectified if necessary prior to operation.

Rules for cleanliness

1. Thoroughly clean all unions and the adjacent areas before disconnecting.
2. Place removed parts on a clean surface and cover. Use sheeting and paper. Use lint-free cloths.
3. Carefully cover or seal open components if repairs cannot be carried out immediately.
4. Only install clean components: do not remove replacement parts from their wrapping until you are ready to install them.
5. Place containers, plastic film or cloths under connections to be opened so that no hydraulic fluid comes into contact with painted surfaces.
6. Shut off open hydraulic lines with closure caps to prevent hydraulic fluid from leaking out.

Assembly overview

The following list pertains to see scheme 60.

1. Right tensioning bar drive cylinder
2. Right main drive cylinder
3. Right convertible box lid drive cylinder
4. Hydraulic pump with valve block
5. Hydraulic lines
6. Left convertible box lid drive cylinder
7. Left tensioning bar drive cylinder
8. Left main drive cylinder

Hydraulic system, filling and bleeding

Note. The electrohydraulic convertible top actuation is designed as a closed hydraulic system. Filling is generally only necessary following loss of fluid (accident, leak etc.). Owing to the travel and the displacement effect of the piston in the hydraulic cylinder, the hydraulic system must be filled with the convertible top folded in the convertible top box. For this purpose, the convertible top must be moved via electrohydraulic actuation.

Filling

1. Remove luggage compartment trim: See «LUGGAGE COMPARTMENT TRIM»(/audi/a4/b6-2000-2006/remont/gauges-instrument-panels/#interior-trim-cabriolet) .
2. Unscrew oil filler bolt -arrow- (2 Nm).
3. Fill with hydraulic fluid G 002 000 using an oil can until the fluid level is between the "MIN" and "MAX" marks.

Bleeding

Note. The hydraulic system is self-bleeding. When the convertible top has been opened and closed several times, the system is bled.

1. Start the engine.
2. Close and open the convertible top 4... 5 times using the electrohydraulic actuation. It must move continuously and jolt-free.
3. Check the fluid level in the fluid container -2- with the convertible top folded into the convertible top box. The fluid level must be between the "MIN" and "MAX" marks.
4. Top up hydraulic fluid, if necessary.
