Im thinking of going from 18" to 19" on my A5 2L quattro. Does it make a massive difference to the ride quality?

Good day! No, I don't think that you will notice, perhaps a slightly harder ride but surely not "massive". My A5 came with 19s as standard and I found the ride very comfortable indeed.

I just did this last summer, I really didn't notice any difference in the ride with the change. Biggest difference I noticed was a slight drop in fuel mileage from the stock Continental 245/40R18 All Season tires to Pirelli 255/35ZR19 Summer Performance tires. Worth it for the appearance in my opinion.
