I have used ECU Pro for the repair of the CAS Module on my 2011 MINI Cooper S. I sent them my Key FOB, ECU and CAS module. 3 days later they emailed me to let me know they received it. Two days after they sent me a video of it repaired and running in their test car. The same day I had an email with the tracking for the return of my parts. I received them and installed them and the car ran like new again! ECU Pro is the only place I would use for my BMW and Mini Cooper Electronics! They are fast, efficient and an excellent quality repair center. I highly recommend them. Chris Katsoufis Fort Lauderdale Florida.
