I have a 2011 Mini Cooper S that had developed multiple issues. To start with the right footwell fuse and relay box was buzzing after I put the key fob in the ignition. Then later the lights stayed on after I had turned off the ignition, killing my battery. I replaced the footwell fuse module and the ignition which seemed to work for a short time. Then a few weeks later the lights wouldn’t turn off and the car started wouldn’t turn over. Everything pointed to the CAS module. So after looking for a solution I found ECU Pro. After initial contact, I sent my ecu , my CAS unit and my key to them. Soon as they received it they checked it and repaired it. Then they sent me a video with my units working in their test car! Two days later I received the cas and ecu units back and I installed them back into my car. It started and ran better than it has ever! ECU Pro is truly the best experience I have ever had in several decades working on cars. They are truly professional, courteous and knowledgeable. I highly recommend their service, they are the best! Thank you again for the quick return!
