Insignia air suspension failure

I had a similar issue with my Insignia. Does it feel like the car is riding directly on the suspension stop? Mine felt rock hard.

Yes, it feels like it's riding directly on the suspension stop. Could you elaborate on which component failed in your case? Was it the air spring?

Yes, the issue was with the air spring itself and the integral valve. Apparently it's a common fault. Given the complexity, a professional workshop diagnosis is advisable to avoid further damage.

Thanks, that confirms the likely cause. I'll thoroughly inspect the air spring and valve assembly, then take it to a workshop to prevent further damage. Your input was invaluable.
