Why do Porsche Bilstein B4 (cars with PASM button) matter?

On PASM-equipped Porsche models, the dampers form a key part of the electronic suspension system. When they age or fail, you may see warning lights, notice inconsistent behaviour between modes, or feel that the car has lost the balanced, confidence-inspiring character it had when new. Replacing worn original units with Bilstein B4 PASM-compatible dampers helps restore normal operation without deleting or bypassing the adaptive features that many owners value.

• Keep your Porsche PASM system functioning as Porsche intended, with working mode selection and dashboard controls
• Renew damping control and stability where original PASM dampers are worn, leaking or noisy
• Address PASM-related fault messages when the damper itself is the root cause
• Support long-term enjoyment and a factory-like character on Porsche models with PASM

When should you review or replace your Porsche Bilstein B4 (cars with PASM button)?

Because PASM dampers are electronically managed, issues can show up as both physical symptoms and dashboard messages. It is worth paying attention to any changes in ride, mode behaviour or warning lights.

• You see PASM warnings or mode-related fault messages on the dashboard
• Damping feels inconsistent between modes, or the car seems stuck in one type of behaviour
• There are knocks, leaks or obvious signs of wear at one or more dampers
• The car no longer feels as composed over bumps as it did when new, despite correct tyres and geometry

If any of these apply, it is a sensible time to inspect the PASM system and related components. Where the fault traces back to the damper units, replacing them with Bilstein B4 PASM-compatible parts can help restore predictable behaviour while retaining the original adaptive functionality.
