Engine Malfunction Reduced Power
This past Tuesday the "Engine Malfunction Reduced Power" light came up on my display, first time ever. Car drove very rough, I immediately parked it, turn if off and 30 seconds later, turn it back on. No problems, no warning lights, everything was perfect. Called my SA, and he told me to bring the car in. The Dealer checked the car, they ran a short vanos test and it came out that the issue could be low oil pressure or faulty vanos solenoids. They checked the oils pressure and it was ok, so it was recommended to change the Exhaust Vanos Sol, they ran a test after, and all systems are ok.
Has anyone had this issue before? Is this repair normal/enough?
P.S. My SA and Dealer (Grayson BMW/Knoxville, TN) are top of the line. Great service, great info, and they've always done right by me, even though I bought the car somewhere else.
