Ordered new wheels for my car and needed a new set of TMPS sensors to monitor air pressure. OEM was expensive so I decided to order this kit since it was cheaper. Was a bit worried they didn't have any reviews for it but went ahead and ordered them. They are pre-programmed to work with my car so check them before ordering and fit them when the tires are fitted. I reset TPMS in idrive settings and after about 5-10 miles of driving everything was synced. The tire pressure is checked correctly. I'm glad I ordered them and they worked straight away, definitely cheaper than OEM. At the moment they have been in the car for 2 months, I will update if there are any problems.
