    Great service

    The shipping was very quick both ways. I had an issue with the DME they sent me but were on top of the issue and had it resloved within 3 days. I am very impressed with their customer service and product.

    Finally got my car on the road.

    After 8 months of immobilizer problems and spending $1,700 (US) at several different BMW dealers my BMW 528i EWS unit would randomly disable my car thus requiring a tow to the dealership and an EWS alignment. The problem was described as a rolling code problem. The dealers were unable to resolve the issue. They replaced the EWS unit two times and haven't solved the problem. The tech support I received from RPM goes far beyond anything I could have imagined. You can’t buy the level of support I received. The RPM tech spent a half hour with me on the phone identifying the problem and that was before I had even bought anything. I bought an EWS and DME kit and it was shipped overnight. The tech had me call when I received the unit and he talked me through the installation. It took about 30 minutes and the immobilizer problem that had plagued me for most of a year was resolved. If you have any doubt about their ability to resolve your BMW problem, just give them a call.
