2002-2012 Mercedes SL55 Active Hydraulic Struts (x4) -A long tube (similar to a shock absorber) that fills with hydraulic fluid forced in at varying rates of pressure determined by sensors on the vehicle. The strut is a perch for a metal coil spring, which helps support the weight of the vehicle. The struts on this vehicle are considered "active" because they can be adjusted hundreds of times a minutes electronically. Much like a shock absorber, the strut dampens vibration and bouncing caused by travel on rough road surfaces. 2002-2012 Mercedes SL55 Height Sensors (x4) - A linkage located near each wheel of a vehicle that electronically measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2002-2012 Mercedes SL55 Hydraulic Lines- Lines that carry fluid from a hydraulic pump to the vehicle"s active struts in order to adjust the height of the vehicle.

2002-2012 Mercedes SL55 Hydraulic Pump- A mechanical pump that delivers hydraulic fluid to the active suspension components. The pump can burn up prematurely when leaks in the suspension system cause fluid levels to get too low.

2002-2012 Mercedes SL55 Suspension Control Module- A computer responsible for the operations of the active hydraulic suspension system and maintaining the vehicle"s correct ride height.

2002-2012 Mercedes SL55 Rubber O-rings- Although they are the least expensive parts of the system, they are responsible for maintaining the seal where all of the hydraulic fluid lines connect. Bad Rubber O-rings cause leaks in the system and leads to part failures.

Look for these indicators that the factory active suspension system in the 2002-2012 Mercedes-Benz SL55 is going bad: A sudden loss of three to five inches of ride height in either the front, rear or entire vehicle. A suspension warning light, at times with a chiming noise, is another sign. Sudden loss of power steering is another indicator of a problem. Vehicle owners can check for extremely low fluid levels in the hydraulic reservoir/pump; leaks around the struts themselves; or leaks at connection points in the hydraulic fluid lines. Experienced technicians tell us that when one major component of the system has failed, the others are right behind it. A complete overhaul of the factory suspension system on this vehicle can cost in the $9,000 to $11,000 range with Original Equipment parts and labor at the dealer. The high cost of suspension repairs on the SL55 is exactly why the Strutmasters suspension conversion kit is such a popular alternative.

When one component of the "Active Body Control" hydraulic suspension suspension system goes bad, the rest of the system follows suit. This is no different for the 2002-2012 Mercedes-Benz SL55. Strutmasters built its active hydraulic suspension conversion system to save SL55 owners time, frustration, and money versus a factory system that fails over and over. Our product is manufactured in the USA and comes complete with one custom-designed suspension light fix module and four pre-assembled coil over struts that bolt right in place of the factory components. Customers appreciate the detailed instructions and online installation videos that guide the repair. If further assistance is needed, Strutmasters" technicians are available to answer questions and provide support. We use dual-action premium coil springs which eliminate the need of installing aftermarket anti-sway bars -- a time savings of more than 10 labor hours alone! Our conversion system allows Mercedes owners to enjoy these wonderful vehicles for many more years WITHOUT spending a fortune!

The R230"s hydraulic vario roof pump aka hydraulic unit is a complex, high-performance pump with integrated valve block, two different output pressures, high-end electronic noise suppression, and high flow rate.

Intermittently working pumps are often mistaken for internal leaks in hydraulic cylinders. While internal leaks occur in OEM vario roof cylinders on occasion, almost every hydraulic pump will fail eventually on account of some design flaws that Top Hydraulics fixes with its upgrade. Thus, your pump will be better than a new one.

Is your pump blowing a fuse every time you try to use it? That is a clear sign for a short from the pump"s electric motor, and Top Hydraulics" rebuild will take care of it.

You send in your malfunctioning vario roof convertible hydraulic pump, p/n 2308000030, 2308000088, 2308000330, 2308000348, aka A 230 800 00 30, A 230 800 00 88, A 230 800 03 30, A 230 800 03 48.

If possible, raise your roll bar before removing the pump. Note that line 100 going to the top of the roll bar support cylinder is always pressurized (on working pumps). Before removing line 100 from the pump, loosen the two inside hex (Allen) bolts that hold the valve block to the pump. There will likely be a small amount of fluid coming out between the valve block and the pump body (fraction of an ounce), but this relieves pressure from line 100.

Do NOT drill a hole in the reservoir! - the filtering in the original pumps is insufficient, and tiny plastic shavings can cause significant damage to the pump and the valve block. Top Hydraulics may have to charge extra for rebuild service on pumps with severe contamination or holes drilled in the reservoir. An additional charge may also apply to pumps that have been abused by DIY repair efforts or severely damged by fire or water. Note that the latter is rare, but we want to mention it for completeness.

The upgrade service for hydraulic convertible top pumps replaces sensitive parts inside the pump with re-designed, precision machined aluminum ones, improves fluid filtering on those pumps that need it, services the valve block, solenoids and check valves, upgrades electronic components, upgrades internal seals, and replaces the electric motors if needed. Early model year vario roof pumps p/n 2308000030 (aka A 230 800 00 30) and 2308000348 (aka A 230 800 03 48) fail very frequently at this point, and should be upgraded proactively. Top Hydraulics" service makes these high-performance pumps better than brand new ones!

Pump removal is quite simple. Disconnect the pump from the wiring harness, remove the bolts that mount the pump frame to the car, and turn the pump on its side. Now you will see all the hydraulic lines going into the pump, held in place by two retaining plates. Each plate has numbers engraved where the lines go in, and the lines (hoses) have the corresponding numbers printed on them in red or white ink. Thus, there is no need for labeling the hoses. First loosen the two inside hex (Allen) bolts that hold the valve block to the pump - one or two turns is enough. There will likely be a small amount of fluid coming out between the valve block and the pump body (fraction of an ounce), but this relieves pressure from line 100. (As mentioned above, there is normally pressure on line 100, and that would otherwise make line 100 pop out of the pump once its retaining plate is moved.) Then remove the retaining plates and pull out the hoses.

We suggest that you remove the mounting frame from the pump - it makes shipping cheaper and easier. Do not attempt to drain fluid from the pump. Instead, wrap the pump inside a large garbage bag, and then inside another one. That should take care of keeping oil leaks contained, and it will protect your pump. Buffer the parcel well inside, and tape it up well.

Top Hydraulics will not guarantee that the rebuilt units will be cosmetically perfect, but they will work well. For example, if you send us a pump in a bent mounting frame, then we may use our best efforts to straighten out the frame, but we will not replace it. We do not replace damaged electrical connectors - please package your pump carefully.
