DME repair

Don’t hesitate to trust RPM Motorworks with your repairs. I reached out to customer service as I was hesitant to ship off parts to a company I didn’t know much about. Lee responded quickly and confirmed they could fix my problem on my E46. He wrote me up an order sheet in an email making it very easy for me to purchase. Overnight shipping there and back. They had my parts there for less than a day. After scanning the car the codes I was looking to whip were gone. Overall great experience and wouldn’t hesitate to use them again.

This is music to our ears! Thank you very much for the awesome review :)

330i zhp cold start idle issues

I’ve been having idle and vehicle dying out issues on my 2004 bmw 330i. I went through normal diagnostics and found no issues with wiring or supply to the idle control valve. I also cleaned out the idle control valve with no success. I began pulling faults and found the dme: self test check sum which was the same faults that required the dme repair. I sent my computer out to RPM motor sports who was quick to support me. I sent my DME out during the week and received the DME quickly with no issues. It was a quick turnaround and after clearing any pending faults the vehicle ran great and no issues on idle or cold starts.

Thanks for sharing your experience! Happy to hear your issue is resolved :)

Cold start issue gone!

2005 BMW 330ci cold start issue is finally resolved. Tried to fix it so many different ways but none worked. I should have done this 3 years ago. Thank you!

That's great Joey thanks for the review!
