Why Your Mercedes-Benz Might Be Drooping on One Side

If you drive a Mercedes-Benz with Airmatic suspension—like the E500 or many other models—you might notice the car sagging after it sits for a while. One owner recently swapped the compressor and valve block, which fixed the car’s ability to raise, but the right side still dropped after 30 minutes to an hour.

The left side stayed fine. A scan suggested a leaking right front strut, but the right rear also went down. That’s confusing, right?

Here’s what’s likely happening: when one front strut leaks, the suspension system can’t hold pressure evenly, and the air can bleed across the rear through interconnected lines or the valve block. The result is both right-side corners dropping, even if only one strut is bad. It’s a common issue on Mercedes, BMW 7 Series, Audi A8, and even some Porsche Cayenne models with air suspension.

The fix usually involves replacing the leaking strut and sometimes the related air line or fitting.

For owners of Lexus, Toyota, Honda, or Volvo vehicles—especially hybrids—air suspension is less common, but similar leaks can happen on models like the Lexus LS or Volvo XC90. If your car is sitting unevenly, don’t ignore it. A slow leak can overwork the compressor and lead to a bigger repair bill.
