In my case, after switching back to a GTI from an Audi, I was shocked by how harsh the suspension felt and how uncomfortable the ride was over bumps, as well as the noise on the motorway. I even experienced multiple rattles in the cabin. I was quite disappointed until I remembered that here in the UK, some dealers don’t properly control the tyre pressure during the pre-sale prep.
When I checked, I was shocked to find that all four tyres were at 49 psi. After lowering them to the factory-recommended 39 psi, all the issues with my car disappeared. Obviously, DCC is a much better system, but I believe that for some people, simply adjusting the tyre pressure could be a quick fix for many complaints about ride quality
