Experiencing issues with your Mercedes W251 after hitting a bump, particularly when it comes to scanning your car for diagnostics? You’re not alone. Many Mercedes R-Class owners encounter suspension problems, and while the inability to scan your car immediately after might be related to various issues, suspension faults are a common culprit that can sometimes be triggered by road impacts. Let’s delve into the discussion around W251 air suspension and explore why sticking with airbags might be the best solution for your Mercedes R-Class.
The Air Suspension Debate: Airbags vs. Coils for W251
When W251 air suspension issues arise, a common debate sparks: should you replace the airbags or convert to coil springs? Some suggest coil spring conversion as a way to avoid future air suspension problems. However, many Mercedes owners, as seen in forum discussions, strongly advise against this conversion, especially for the rear suspension. They argue that sticking with air suspension, specifically replacing faulty airbags with quality aftermarket options like Arnott, is a more sensible approach.
Why Airbags Might Be Better for Your W251 Mercedes
The original air suspension system in the Mercedes W251 offers features that many owners value, such as automatic leveling. This feature is particularly useful when carrying heavy loads, ensuring the vehicle remains level, safe, and comfortable. Converting to coil springs means losing this functionality. Furthermore, replacing rear airbags is often described as a straightforward DIY job, and the cost of quality replacement air bladders, like those from Arnott, can be quite reasonable. Forum members point out that the conversion to coils is actually more complex and potentially more expensive when considering all factors.
Addressing Air Suspension Durability Concerns
Concerns about the longevity of air suspension systems are valid. Airbags are made of rubber and, like tires, are subject to wear and tear over time, especially from road debris and constant flexing. However, it’s important to remember that coil springs are not lifetime components either. Springs can fatigue and weaken over time, especially in heavier vehicles, leading to a spongy and less controlled ride. Therefore, regular maintenance and timely replacement of worn components are crucial for both air and coil spring systems. Choosing quality replacement airbags and addressing any leaks promptly can ensure the continued smooth ride and leveling capabilities of your W251 Mercedes without the complexities of a coil spring conversion.
