This is not the first time we dealt with this comapny. We had 2010 BMW 328I for footwell Module and they veryfied that it was a bad oneand need a replacement. Plug and play and work great has no issue till nowsaday. It has been 3 years since then. Indeed, We sent our 2013 BMW X-5 Twin turbo ECU to verify that the injector drivers are not working and they confirm it that the ECU was bad and need a replacement. We ordered one and put it back within 2 week after we sent out and plug and play again...no need programming and no issue so far. We drove the vehicle for 2000 miles at no problem.
