Product Information

This is a BMW Repair Service for BMW E70 / E71 X5 50iX and X6 50iX with N63 engines equipped with DME MSD85.1 that have the BMW Fault codes listed under "Popular Fault Codes". 

Please Note: There is a risk that the EGS will not shift gears after the repair is complete. If that's the case, you will have to send us your Mechatronics (EGS), CAS Module and Key after that to Remanufacture the Mechatronics and adapt it with the CAS and Key.
This service will cost an additional $699 + shipping. 

Popular Fault Codes

  • 2F49 - Anti tampering protection
  • 2F4C - EWS DME message incorrect
  • A102 - Immobilizer anti tampering protection

The reason this happens is because the CAS Module and DME (Engine control unit) loses its Sync Code between them. Even with an Autologic or ISTA-P you will NOT be able to complete a CAS-DME Alignment. The Only way this will work is that you send us your DME, CAS and Key.

        They were honest with the diagnosis and return.
        Would use them again at a drop of a hat.

        Reprogrammed the CAS and DME for my Z4

        I own a 2009 BMW Z4. The battery had gone dead and that caused all sorts of problems. I replaced the battery but then the car would turn over but not start. I took the car to two local repairs shops that work on BMWs and they were not able to get it running. All they were able to determine was my car was in lock out due to the anti-theft being triggered. Their "solution" for the problem was to replace the CAS and probably the DME also. VERY expensive and the parts were back ordered. It would be at least 2 or 3 months before the parts were available, if then. I did some research and found a number of sites that claimed to be able to reprogram the CAS and DME to resolve the problem and RPM Motorsports stood out due to their references. I called them and ended up working with Lee. He was fantastic. I explained the problem and he diagnosed the problems and the fix which involved reprogramming the CAS and DME so they were properly sync'd. Lee explained they would send me an overnight shipping label that I would use to send the CAS, DME, and key fob to them. I received an email with the UPS label attachment and printed it out and took the package to UPS. 3 days later I received the reprogrammed CAS and DME and key fob. Installed them and the car started immediately and there were no other problems. Everything worked as it should. Lee in particular and RPM in general were great to work with and I would highly recommend contacting them if you have problems with your BMW. The service was great and they know what they are doing and the price was extremely reasonable.

        Thanks so much for sharing your experience and for the kind words Jim!
