    X3 DME checksum failure
    Hi Henry, I took a closer look into this, seems your first DME purchase was in 2012. The DME got another checksum error in 2015, even though it was out of warranty, looks like RPM covered it free of charge for you. Following September 2019, we asked you to pay 50% of the labor cost, I just want to inform you the following reasons why this DME might fail again. 1. Based on BMW, this DME cannot in under any circumstances be in an environment below 30 degrees. in your case its below 40 degrees in the winter where you live. 2. If you don't find a way to maybe cover this ECU with a certain type of plastic bag that can at least protect it from going below 10 degrees then this will happen again. I hope this helps you and the community onto why MS45 DME's fail in general, its either too cold or too hot. The hot problem is always solved by the E-Fan inside the DME box. Zach Level 2 support
