Q5 Air suspension retrofit or Koni Special Active on Q5 B9

[mistaleung]

I love my car, it is comfortable and practical
As a family car, I am trying to push its comfort level to the maximum level
So far, I have done acoustic glass retrofit, Fine Ash Grain interior trim, OEM Deep-pile textile floor mats and sound deadening

I am now considering an air suspension retrofit, found a second hand set and the total cost with installation is approx. $4,400 USD
It will cost me a fortune, and will likely to increase the maintenance cost

On the other hand, I have heard good things about the Koni Special Active shocks, which focus on comfort and high speed stability
It only cost a fraction of air suspension retrofit

Is it worth to pay more than $4000 USD for an 2nd hand air suspension?
How is the comfort level of an air suspension? (I have never ride or driven a car with air suspension)
Does it make more sense to install the Koni instead?

Thank you

i'd check on the koni website first because if yours has s-line suspension it might not be for your car something todo with the oem s-line springs being shorter than the normal ones and if fitted regardless of this warning you'll void the warranty... so make sure, if your car is an s-line spec it might not be an option.

How old is the second hand system? Air springs can fail around 100K miles and aren't cheap to replace.

It’s around 50k km, new hoses will be used
