E82 120i Intake Tubes
Hi, I have a 2012 120i. The car loses power mid RPM range. I have checked the DISA controller and it appears to be doing everything it should. However, I have noted that the variable intake tubes don't slide easily and appear to be stuck. I can get them to move and have sprayed them with a lubricant. Reassemble the car and it goes well for a period of time and then loses power again.
Has anyone had this issue? Does anyone know if there is a rebuild kit for the manifold or is it a full replacement. If its full replacement, does anyone know if their is an aftermarket alternative?
