My 2020 X4 Live Valve has intermittent issues. Sometimes the EPS goes out randomly. All grounds good, voltage good - I spoke to a guy who had his EPS unit replaced, and his issue was resolved. Must be related to a faulty heat sensor in the EPS unit. I know they are designed to reduce voltage to the unit if it senses higher heat. Problem is, mine will come and go whether the unit has been running for 1 minute or 2 hours. I've reached out to dealer. We'll see what's up.
