When my mechanic diagnosed that CAS Who is bad, he said he didn’t even deal with it and to send it to the Mini Cooper shop. They started with a $5000 repair cost that wasn’t gonna happen. Then I found the ECU angels. I did need to replace one of the parts and added an extra Key. They reprogrammed everything and actually sent me a video with my parts running in a car just like mine. And what did I pay? With my amazing Mini Machanic, about $1500. When I got the confirmation number and the tracking, I realize that they were sending it back to me because I had messed up the return address. I called them immediately and they were able to re-route the package to my mechanic. They just go above and beyond.
