So how are people running their S3's in? Do modern engines really need a 1000 miles running in period? I once had 2 brand new Renaultsport Clio 182's, the first an 04 plate which I ran in for 1000 miles (not going over 4000rpm), the second an 05 plate which I gave the beans from having 15 miles on the clock. The 05 plate was noticeably a lot faster for the duration of my ownership. So does a new car like an S3 really need 1000 miles running in?! It would take me months to run it in as I don't do many miles!
