Greetings, everyone.

The 2006 CLK vehicle in my possession is equipped with Orthopaedic Seats that are now non-functional. Based on my observations, it seems that the lack of audible pump activity suggests that the issue is not related to a loose air pipe.

I comprehend that the pump is situated inside the rear boot area; nonetheless, I am interested in determining the specific location of the fuse responsible for the pump's operation. Although I acknowledge that my inquiry may be speculative, it is plausible that the solution might be as simple as locating the fuse.

In the event that it is determined that the pump is the root cause, I kindly want information on a reputable supplier of replacement parts or used equipment, namely a functioning second-hand pump.

I would want to express my gratitude in advance for any assistance provided.

If the vehicle in question is identical to a 2000 Clk model, then it is equipped with a central locking system that is operated by the same pump. However, it is important to note that the activation of the pump is necessary for the functioning of the seats, since not all vehicles are equipped with this feature. My vehicle had a malfunction after the installation of a replacement hydraulic pump, despite the fact that the component numbers matched. It is likely that the pump requires coding using a Star scanner. Has your device had a pump replacement?

The automobile has been in my possession for a duration of two weeks. The service history of the vehicle is rather lacking in depth. However, I find solace in the fact that the car was accompanied by MOT certificates from the last five years, which provide a comprehensive record of the mileage. Consequently, I am inclined to believe that the mileage is authentic.

However, there is a lack of any other service records. It is evident that someone has made attempts to modify the vehicle since the fittings under the passenger seat have been tampered with. Nevertheless, apart from this indication, there is a dearth of information on any other maintenance or alterations that have been carried out.

Do you believe that an independent variable may be of assistance?

I am certain that an individual will possess the capability to provide assistance. The location of the pump in my vehicle is situated inside a foam enclosure, sandwiched between layers, and positioned below the trim in close proximity to the hinge of the driver's side boot, internally within the boot compartment. There are fuses placed below the boot carpet that may be of significance, while others may be found under the hood and at the driver's side dash end. As previously said, it is important to ensure that the seats are appropriately enabled, potentially making the task rather straightforward.

Were you successful in determining the cause of the issue? I am now experiencing a similar circumstance.

I have successfully resolved the issue pertaining to the malfunctioning orthopaedic seat in my 2009 CLK. The pump is located below the trunk, specifically underneath the fuse box. It is surrounded by two foam cushions. The pump motor required disassembling and cleansing, which proved to be a quite intricate task. However, after dedicating half an hour to the process, the motor was successfully reassembled and restored to its operational state. I now need to address the issue of the seat belt retraction mechanism, which seems to be functioning sluggishly.

Consider applying silicon spray to the belt. This approach seems to be effective in the majority of instances.

The functionality of my pump is contingent upon the initiation of the vehicle's engine. The estimated duration is around 20 to 30 seconds. Have you conducted an inspection subsequent to initiating the vehicle's ignition?

The pump is situated in the left-hand corner of the boot, next to the SAM unit, and is enclosed by a block of grey foam. One of the prevalent issues encountered is carbon burn on the commutator, which can be remedied rather easily after the removal of the pump motor. A comprehensive guide is available on this platform, which provides instructions on how to do the task.

This is the intended functionality of the system and does not cause any issues. The functionality of the pump is limited to a brief duration, since it only operates when starting the vehicle. In accordance with its intended purpose
