They worked perfectly on my 2008 BMW 335i with no problems. I took the wheels and gauges to Costco for fitting, mounting, and balancing, and Costco had the tools needed to do whatever it took to get them working (not sure how much setup their gauge needs, but they said it wasn't a problem and they were right - I think most/all tire shops these days have the programming tool needed for tire pressure sensors). The sensors were immediately recognized by the car's computer and after several months and several thousand kilometers there were no problems to report.
