BMW 5 E61 Rear Air Spring (Air Suspension Bag)

The BMW 5 Series E61 was produced in the period from 2003 until 2010 and is the successor to the BMW E39. The model set new standards in terms of safety, comfort and sportiness in the high-end vehicle segment. To date, the touring version of the BMW 5 Series, which was internally referred to as the E61 series, is considered one of the safest and sportiest estates in its class. Part of its success is due to the air spring system of the rear axle.

The Suspension System of the BMW 5 Series E61

While the E61 has air suspension on the rear axle, a conventional spring strut with spiral steel springs was installed on the front axle. Nevertheless, thanks to the intelligent level control, the vehicle is always kept at the same level regardless of the load. This also applies when a trailer is attached. The Aerosus air suspension is a new product of the highest quality. The air spring is suitable for all BMW 5 Series E61 models produced between 2003 and 2010 and can be installed on either side of the rear axle, both left and right. To ensure the air spring can be installed without any problems, an additional compressed air connection is included in the delivery.

The Advantages of an Aerosus Air Spring

The BMW 5 Series E61 is rightly considered one of the safest and most comfortable estates in the luxury class. In order to highlight and preserve these qualities, we have created a product which is in no way inferior to the original part. We always strive to keep the price of our components as low as possible. The air spring for BMW E61 by Aerosus was designed to the highest quality standards and had to withstand a whole series of checks, such as a burst test and a continuous load before its market release. All our spare parts go through a quality control carried out by experts in Germany.

You Must Pay Attention to This when Replacing the Air Spring

As with many other vehicle components, the air spring is a part prone to wear, which can suffer a defect over the years. This ongoing process is often noticed too late and is usually due to a leak. In addition to a warning on the dashboard with a “Level Control Defective” sign, you can also recognise a faulty air suspension by the fact that the position of your vehicle is no longer horizontal after being parked for a while. If an air spring leaks, then the problem should be taken seriously with immediate repair of the defect. If you don’t replace the defective parts in a timely manner, then the compressor will constantly try to maintain the level of the vehicle. The permanently working compressor overheats quickly and malfunctions as well. In this case, you must exchange not only the defective air spring but also the compressor, which is expensive.

It is recommended that air springs of an axle are always removed and exchanged in pairs, since the wear of the springs on an axle is usually the same. In addition, a replacement of both air springs can save installation costs. When buying online, we offer you a 10% discount on pair purchases.
