Aerosus Airbags - is there a catch?

[footfang]

Hi

See my other post about my C6 A6 Allroad with what looks like a leaky rear air suspension bag. Ive been googling and Ive found these replacement airbags for my model of A6. At £134 each inc VAT this seems to be a great price, especially when other suppliers sell something similar at £750. Has anyone out there had experience of this company and its products - is it too good to be true?

I replaced both rear airsprings using Aerosus parts. Quick delivery, perfect fit, no issues so far.
I needed an M6 spline bit to remove the lower screw fixing.

When you release the pressure from the airspring, the suspension arm moves up.
Tip: put it in lift mode before setting jacking mode & raising the car. Then wedge the suspension down before you release the pressure
