Audi Air Suspension

Audi has installed Air Suspension systems on many models (All Road, A8 D3-D4, Q7) for dynamic adjustable levels, it’s a complex system with many sensors, air pump, air tank and air shocks. My A8L hasn’t had any of the suspension issues up till now, 93k miles, but in the forums, many have experienced the problems

A8L Suspension Pump Retrofit

All A8 D3 Air Pump will fail during its lifetime ~100k+ miles. Wabco is the original company for this pump. Someone found out that Mercedes pump is being sold cheaper than the Audi Pump for some reasons. Someone also swap the Mercedes pump to run Audi Allroad which may also work for Audi A8 D3.
