Conversion of the rear suspension

[Howard_silver]

I own a 2012 E250 W212 Estate that has consistently shown issues with its rear air suspension.
Does anybody know whether it is possible to uninstall the airbags and replace them with springs to create a traditional springs/shock absorber system? I am selling the automobile and I am looking for the lowest feasible price.
What kind of springs are employed, if it is possible to achieve?

There is a kit available for purchase, however I am unable to recall the specific location where I encountered it. Although I can recall, it was not inexpensive. Undoubtedly, the cost is not sufficiently low to justify replacing the air suspension. Additionally, it is important to consider the financial and desirability implications of removing the air before selling.

I had difficulties with the back air system, prompting me to explore the possibility of switching it to conventional springs. However, ultimately, the air conditioning was repaired. The system is not too complex, but it typically has a lifespan of around 10 years. Identifying faults in the system may be challenging.

I ultimately replaced all components of mine. Paradoxically, the airbags themselves were functioning well, while the issue was with the leaking lines and compressor.

Thank you. I have replaced almost all of it, totaling over 3,000 units, across two separate garages. Due to the extensive amount of time my automobile spent in the garage, I decided to purchase another vehicle.

I am experiencing difficulties with the rear suspension of my 2011 S212 E350 CDI, which has covered 90000 km. I believe that the suspension requires calibration after the cleaning of the pressure release valve. I am interested in purchasing a scanner that has the capability to do the above task, and ideally, other functions such as notifying the Engine Control Unit (ECU) when certain components are replaced. I am aware that the Youcanic scanner has the capability to calibrate the suspension. However, I am also considering Autel and Launch scanners. The issue I am facing is the lack of clear information on the capabilities and limitations of the scanners for motherboards like mine. Assistance in this matter would be much appreciated.

My mine has been thoroughly examined by two very skilled mercenary experts, but unfortunately, they were unable to find a solution. As a result, I am now attempting to fully remove the air system.

I had a similar notion, but, I discovered that the conversion kits are very costly, and transitioning also necessitates alterations to the electrical and electronic components. At now, I lack the necessary expertise to do this task, and entrusting the automobile to a professional would result in a substantial charge up to several thousand pounds, which exceeds the car's value.

[Howard_silver]

Indeed, I anticipated that it would be costly, considering the typically high prices associated with most MB products. Regrettably, an automobile lacks value in the absence of a suspension system.

I concur. I see that you have previously consulted with two "specialists". Based on my own observations, I have found that these individuals exhibit a variety of characteristics. Consequently, I have determined that it is most advantageous to do the task independently, if feasible. That is why I am inquiring about members' experience with scanners. We have already exceeded the car's value in our expenditures, as shown by my earlier blogs.

Since you have purchased another vehicle and considering the current value of your E250, it may be prudent to contemplate selling it for parts or repair. I often contemplate my own thoughts in a similar manner.

I made extensive modifications to my (independent) version, and if I recall correctly, it cost me less than 2,000 dollars. However, it required around six trips. The most exasperating aspect was that the majority of the malfunctions do not generate error codes, necessitating a return to fundamental troubleshooting methods to identify the problem. Is your situation still deteriorating? What items or components have you had substituted or exchanged for anything else?

Initially, my possession had damage caused by water and rodents, with the suspension still being a persisting issue. The ECU, ignition, front SAM, and gearbox control units were replaced, and minor repairs were conducted on the wire looms. The automobile remained in several garages for many months and incurred a total cost of around £6,000, which includes the expenses for the brake system repairs we had done upon purchasing the vehicle (replacing all brake pads and discs, installing new front callipers, and exchanging rear callipers). The independent contractor who addressed the rodent-inflicted harm successfully restored it, but said that they would need an additional two weeks to complete the task. What would be the additional expense of that? Although a nearby automotive repair shop offers the service of adjusting the suspension for a fair price, I am interested in attempting to do it myself. Accomplishing this task necessitates the possession of a high-quality OBD2 scanner (which may be more expensive than a visit to the nearby automotive repair shop, but is expected to provide long-term use). While I am aware that the Youcanic scanner is capable of doing calibrations, I am interested in acquiring a scanner that has additional functionality, such as the ability to inform the ECU when a new module is installed.
Meanwhile, our Mercedes-Benz provides a very smooth and enjoyable ride when it is functioning properly - we much appreciate the level of comfort it offers.

Hey, I was perfect after my suspension at the Bristol dealership.
