Have you inspected/cleaned the Check valves? They filter the oil that goes to the Vanos, so can cause a similar issue as jammed solenoids.

Continental MAF is basically just the new branding of the old VDO and VDO/Siemens branded MAF sensors - at least that's what I remember reading when I replaced mine (was a gamble that didn't pay off in my case, so still have the original one too).
