    X3 DME checksum failure

    This was the 2nd time the DME failed after my purchase from RPM. It was fixed at 50% discount and turned around quickly once the repair cost was approved by management.
    Hopefully this time the DME will not fail again.
    Thank you for the discount and resolution.
    Henry

    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

    Good product rather tedious ordering process

    Was almost ready to try elsewhere due to irritating ordering process with answering services and US dollar pricing even for Canadian to Canadian transactions.
    Once the order was committed to it was smooth sailing. Printed out the shipping label and stuck it to the box. ECU was returned in a few days and it worked perfectly.
    I would use them again.
    My suggestion is to operate as proffesionaly as the website looks.
    Overall satisfied with the experience.

    Hello Ryan, we truly appreciate your review. We are always keen to get things just right. I do somewhat agree with you on some points, like the answering service. Our answering service is activated and diverts calls when calling outside of business hours. It is also activated when our call capacity is reached, which is about 8 calls at a time, managed by a team who are specifically trained to fully answer the call. In regards to the currency, we support 4 major currencies, our primary currency is USD, which can be easily adjusted according to your needs. I have looked closer into this and realized that there was a delay in the response of the PST number issue. Our staff members are not authorized to deal with this kind of accounting. This is why they gave you a 7% discount to try their best to exempt you. I went ahead and exempted you from any PST tax in the future with your PST number attached to your account. Please accept our apologies and we will make sure this works a lot faster on your next order. Please accept the account invitation so when you log on in the future, the exemption will be automatically applied. Regards, Seth

    No start /throttle adaption issues

    Had replaced throttle body, wiring harness, and relays that did not resolve issue. Noticed I had several of the codes mentioned in (DME checksum error) on RPM website. Sent for repair and is running perfectly now. Thanks, RPM also turn around time and shipping is very fast.
