Description
Mercedes-Benz R230 SL-Class Vario Roof Hydraulic Pump – OEM 2308000030
Genuine OEM Mercedes-Benz hydraulic pump assembly for the Vario Roof power retractable hardtop system used in select R230 SL-Class vehicles.
This is an original Mercedes-Benz hydraulic unit, not a universal aftermarket pump. The R230 Vario Roof system uses a sophisticated electro-hydraulic system to raise, lower, latch and store the vehicle’s retractable hardtop.

About the R230 Vario Roof Hydraulic System
The Mercedes-Benz R230 SL uses an electro-hydraulic Vario Roof system to operate its power retractable hardtop.
The hydraulic pump is the heart of this system, generating the hydraulic pressure required to operate the roof mechanism through its hydraulic cylinders and integrated valve system.
The original R230 hydraulic unit uses multiple hydraulic circuits and an integrated valve block to control the complex sequence required to open and close the retractable roof.
Common Symptoms
Possible symptoms associated with R230 Vario Roof hydraulic-system problems can include:
- Convertible roof will not open or close
- Roof stops during operation
- Hydraulic pump motor does not operate
- Weak or slow roof movement
- Roof begins operating but fails to complete the cycle
- Unusual noise from the hydraulic pump
- Vario Roof malfunction warning
Important: These symptoms do not necessarily mean that the hydraulic pump has failed.
The R230 roof system also contains hydraulic cylinders, electrical switches, sensors, wiring, control electronics and hydraulic lines. Low hydraulic fluid caused by leaking cylinders can produce similar symptoms and can place excessive stress on the hydraulic pump.
Proper diagnosis is strongly recommended before replacing the hydraulic unit.
Condition
This is a used genuine OEM Mercedes-Benz component and may show normal cosmetic signs of age and previous use.
Please carefully review all product photographs. The photographs show the actual condition and components included with the item.
Inspect the hydraulic reservoir, electrical connections, hydraulic line ports, mounting points and housing before installation.
Only the hydraulic pump assembly and components shown in the photographs are included. Hydraulic lines, cylinders and other Vario Roof components are not included unless specifically pictured.
Important Hydraulic System Notice
Before installing a replacement hydraulic pump, the complete Vario Roof system should be inspected for hydraulic leaks.
The R230 uses multiple hydraulic cylinders throughout the retractable-roof system. Aging cylinder seals may leak hydraulic fluid, resulting in low fluid levels and excessive pump operation.
Installing a replacement pump without correcting existing hydraulic leaks may lead to continued roof problems and possible damage to the replacement pump.
Installation
Professional installation and proper diagnosis are recommended due to the complexity of the Mercedes-Benz R230 Vario Roof hydraulic system.
Hydraulic lines must be connected to the proper ports and the hydraulic system must contain the correct type and amount of hydraulic fluid.
Fitment Verification
The most reliable way to confirm compatibility is to compare the complete OEM part number on your original hydraulic unit with:
A2308000030 / 2308000030
