I purchased a 2015 Audi A7 Black Edition a two and a half years ago, which I love. It came on 21" wheels and 275/30 tyres. Initially, I found the ride quality firm but acceptable, but after a while I became less and less happy with it. It felt harsh on urban roads, which are often poorly surfaced and have potholes and badly repaired road surfaces. I contacted Audi Customer Service to see if anything could be done to improve things, but the reply I got was not helpfull and I was advised that only OE specification parts could be fitted. I left it at that for a while but continued to brouse the internet for information and eventually came accross something on YouTube about cars with sport suspension but not specifically Audi. The piece was promoting Koni Special Active Dampers, which have a dual damping rate and are designed to absorb high frequency shocks while retaining firmness for lower frequency movements. I contacted Koni in the UK to discuss the possibility of fitting these and was advised that dampers designed specifically for the problem I was experiencing were available for my car. Long story short; I have recently had them fitted and they have transformed the ride quality of the car. The jarring has gone but the firmness on the open road is still there and roll stability is unaffected. For the record I have no connection with Koni. Alan G

I have experienced this problem a number of times on my A7. Fortunately I purchased wheel and tyre insurance when I bought the car so the replacements were covered. I was advised to change to Continental by one Audi body shop, which I will do the next time I need to replace tyres. I have been trouble free for a while now. Touch wood! Alan G

I have a 2015 A7 Black Edition on 21" wheels and lowered Sport suspension. I find the ride uncomfortable when driving on poor surface urban roads. I have asked Audi Customer Service if there is anything that can be done about this but they were not interested. I have now found that Koni produce a shock absorber called Special Active, which is a dual rate damper that absorbs severe bumps and pot holes bit retains a firm ride on good surfaces. I am seriously thinking of fitting these and would like to here from anyone who has experience of them.
