I think the issue is really 1st year production issues rather than where the vehicle is built. Most manufacturers seem to have problems with that, although the Japanese seem to have a better handle on it than most.

My buddy had a 1st year E36 that he had to lemon-law. He seriously had a 2" thick stack of repair paperwork to give to BMW's rep when they gave him static about a swap. My 3rd year E36, built in Germany, had several problems from the get-go. One entire headlight assembly kept popping out. It's no fun to get out of your brand-new BMW and have your date ask you why the headlights are hanging loose by the wires! The tranny shift lever also had a sheared-off bolt that kept it from going into park occasionally. Another fun issue on dates until service finally figured out what the problem was.

My E46, built in Germany, had 4 window regulators fail. Driving with a window all the way down when it's 115F outside really isn't fun. And the sunroof died the 2nd time I used it, and there were all sorts of odd clunking and thumping sounds that took years to iron out.

Anyway, my point is that anybody that buys the 1st year of any model, especially a German car, should expect more than their fair share of problems no matter where it's built. Oh, the 335i also had issues with overheating. Apparently BMW decided that non-SP models didn't need an oil cooler and so left it off if you didn't order the sport pack. Those wacky Germans!
