Ive got an 07 335i coupe and its a blast but lately when i really get on the gas 4k if its cold and 5k if its warmed up the reduced power light comes on but no engine codes. I did some live scans but nothing looked out of the ordinary. Ive cleaned the vanos solenoids and done the spark plugs to no avail. Any ideas? The bmw dealer near me is a rip off. Im going to get it dynoed soon to see if anything comes up then. The car drives fine before during and after so im really at a loss.
