I am completely satisfied with the repair to my mini cooper frm module. Mini Cooper recalled it and after 4 months had no solution to the problem. My windows, blinkers, hazards, brake lights, sunroof didn't work. I had this module replaced by the Mini Cooper dealership where I purchased new in 2010. The new one did not work and they told me another module was bad charging me $1200 and another $900 but that was on indefinite back order. I had them remove it replace original one and that is when I sent it to ECU and now everything works just fine. I only wished I had just sent it off to begin with. It was easy to take out and replace and they provided a video. I am a 63 yr old woman so don't doubt yourself because you can do this. The turn around time for service was great. I mailed it on a Thursday afternoon by USPS in bubble wrap with bubble wrap envelope they received on Friday. I received it back by Fed Ex Express on Tuesday. I called them to ask a question about the battery cable they referred to in directions and they were great in telling me what to do. I will recommend them to anyone with Mini or BMW problems. Excellent customer service and easy to navigate online info that you give them before sending.
