Offering the same functionality as in a new car

Even in premium vehicles, air suspension is usually still an expensive option.
This is due to the complex technology involved, which Bilstein explains makes it possible to dispense with the traditional compromise between ‘safety or comfort.’
Bilstein says it has played a major role in the development of these suspension parts in collaboration with leading vehicle manufacturers.
It explains the result is the Bilstein B4 air suspension modules for series replacement, offering maximum driving comfort and, at the same time, a safe driving experience thanks to optimised damping force and comfortable suspension.
Active air suspension modules are highly complex systems that not only allow the driver to select their preferred damping via adjustable characteristic curves, but are also able to recognise extreme situations – such as an evasive manoeuvre – and instantly adjust the damping force.
Bilstein says the most modern adaptive systems work with various sensors and can adjust the damping fully automatically to the road conditions, the load and the driving speed.
Due to the complexity of the systems, it is particularly important that the workshop pays attention to the integration capability of the air spring module and the quality of the components when carrying out repairs.
This is because one of the prerequisites for the positive characteristics of air suspension is the reliable and complete integration of the air suspension modules into the vehicle’s electronic system as specified by the manufacturer.
If communication between the vehicle sensors, on-board computer and air suspension module is not 100 percent reliable, the air suspension system is non-functional.
It also becomes a safety risk: the driver relies on the accustomed performance of his suspension, but in an emergency, the original reserves are not available.

Bilstein says that thanks to its expertise in series production, all Bilstein B4 air suspension modules can be easily installed (‘plug and play’) in a wide range of vehicles, ensuring 100 percent compatibility and full functionality.
The second important aspect is the quality of the individual components.
The advantage of the air suspension module design is that the actual air suspension, the shock absorber and the electromagnetic control valve are integrated into a single unit, making installation easier for the workshop.
Since the complex technology is expensive, remanufactured components (reman offers) could be an interesting alternative if repairs are needed, says Bilstein.
The company notes a problem with this is that the integrated gas pressure shock absorber and the control valves are often reused from the old part without any changes, and only the visible suspension bellows are replaced.
It says the workshop usually does not have the means to check the condition of the other components and as a result, an air suspension module is installed that only has a new air suspension spring, even though other components may have worn out unnoticed.
Bilstein explains that its B4 replacement air suspension modules are new parts in series production quality, assembled and manufactured to OE standards.
It says this enables the workshop to ensure driving performance as if it were ‘ex works’ and to restore the optimal driving experience for the driver.
