I've just bought a 97 BMW 323i. (150ks / 65000 miles) Test drive etc was fine, driving it home, I noticed it was VERY rough at about 100kmh (60mph), I rang the previous owner who said it sometime happens in economy mode (auto) and change to sport mode, this should fix it... and it did. Puzzled! Any ideas? I was going to do a transmition fluid change this week not sure this will help....
Any ideas my dear BMW afficondos?
