Saved my car from being junked

I paid $2k for my car, so the idea of spending $500 on this one service was a hard pill to swallow. But once the cold weather set in, I bit the bullet. The car would have a horrible surging idle when it was cold and turn off randomly before it even could get warm. I’d have to reset the codes constantly to get it working after it stalled. The people at rpm were super helpful and made the process very simple. When I received my ecu back I installed it back in, and it has worked flawlessly ever since. Highly recommended if your e46 has cold start issues.

Thanks Dillon! Glad to hear everything went smoothly and that the car is back on the road!

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 :)
