Helpful, honest support, fast service

Thanks so much for helping me figure out my 'no crank, no start issue!' They responded to all my voicemails, emails in a short time. Got the EWS delete and now my mini Cooper runs again 😊

We appreciate the feedback Krystal! Happy to hear that your Mini is good to go!

(Overseas) EWS and DME failure fix

I drive a mini cooper (2006) in S. Korea. One day my car would crank but wouldn't start, so I went to the official mini service center based in S.Korea. They told me that the rolling code was off and I needed to get a replacement for the EWS (EWS 4.3 in my case). So I asked them to order one for me and they told me they have to order it from Germany or something and that it could take up to 1 full year. At this point, waiting 1 year didn't make sense but I had no other options. After 5 months of waiting I got fed up and started looking online and found RPM motorsport. I emailed RMP motorsport immediately explaining my situation, and they replied extremely promptly with detailed explanations. RPM motorsport told me that I could send my DME to them and they could fix it so it wouldn't read my EWS. I sent them my DME half way around the world and got it back in like a week and a half (less than 2 weeks for sure). Installed the DME and car starts right away. Thank you so much for this and your kind/prompt emails. S.Korea is known for kind and quick services, but compared to you guys the service in S. Korea is a joke now. By the way I saved a lot of money too. The mini service center asked for over a grand (in dollars), RPM motorsport was half that including shipping. Again, thank you very much you guys are the best!

Wow thank for the awesome review and for taking the time to share your experience Charles! It really means a lot and we are very happy to hear that your Mini is alive again!


Absolutely excellent service and turnaround time.

Thank you! It was our pleasure :)
