Is unplugging the exhaust valve actuator a good idea?
Hello everyone,
For a while, I have been thinking about whether or not I should unplug the exhaust valve actuator in order to keep the valve permanently open. After hearing the difference today, I am probably going to unplug it, but I have a concern that has been keeping me from unplugging the valve. For those who have unplugged the valve, has it triggered any check engine lights? In a previous BMW, the check engine light was triggered due to the failure of a sensor. Would unplugging the valve result in the same issue? For example, when the car's computer wants to tell the valve to close, but it doesn't because I have unplugged it, will the computer deem the valve as unresponsive and therefore trigger the check engine light? Sorry for the sort of long post, I just want to make sure that I don't run into any problems down the road. Thanks |

I just removed the spring that operates the valve, not the electrical connector. You probably dont want water to get on the connector when its unplugged
On top of it, I think its not the actual opening and closing that always rattles, its that spring, so removing it and tightening valve stopped my annoying rattling. Takes 5 minutes since its super easy to access under the car (no lift needed) Last edited by Kolyan2k; 09-14-2017 at 03:06 PM.. |

You can unplug it but I promise you there won't be a change in sound once the motor is warmed. The valve has little effect on noise, burbles, etc. once the motor is warm plus in most modes, it's open after about 2 minutes of driving/starting.

Mine has been unplugged for 60K miles or so. I taped up the connectors. It's not a sensor, it's the connection for the flap motor. I had my resonator deleted a few months ago and this was the result. This is not a cold start. Cold start is significantly louder than that. Pay no attention to how dirty my car is at the time.

I didn't think they would. I was asking in general if anyone had the dealer say something. Sometimes you take your car in for a rattle or somthing like that, and they are normaly quick to blame an unplugged connector that has nothing to do with it.
