Alternative to DRC

[ABS2788]

So it’s come to light that my rs4 b8 DRC has failed. The car is now very bouncy to drive.
Audi have quoted £10k to replace whole system.
What’s a good aftermarket alternative to replacing drc system can people recommend?
Thank you

Isn't there any repairer's, assume its the shocks that are the issue?
