One of my S3 LSS dampers was leaking and the others were pretty tired. New ones are £600 a corner I’m told. And on backorder anyway. Nitrons not much different AND I don’t like the idea of those in any case.
Contacted David Masters at Bilstein UK via this page:

…and he said no problem, approx 2 weeks turnaround.
So I dispatched these …

… and got these back today…

Around £180 per corner including fresh springs. Delighted

Only have to fit them now

But hopefully this is of use to others with tired Bilsteins. Prob cheaper if you have standard rather than LSS too.
