I have no codes, very good gas mileage, great power.
I only get the stumble at idle, don't see or feel it at cruise RPM.

Any ideas where to start looking?

Hi , when I changed mine out the rpm were around 500 , to low for the eninge to function correctly , when I would start the x5 the LOW OIL PRESSURE , warning would come on, After I changed it the rpm's are 650 and idles great, And I changed my vanos solenoids and now , the engine is like new ............low end torque is back , she flies like like bird now.and mpg is much better too, tranny is shifting on cue ...............fun to drive now

Been reading up on solenoid.
Are the N62 units the ones that get clogged screens?

A lot cheaper than 400 bones to replace.

Was cleaning an option?

Yes they do get clogged but only if You don't change your oil regularly,but...............what happens is that they get stuck in the advance [something about the o rings] position [meaning high rpms or pushing the throttle ] and the engine feelings like a lump .So changing them is better then just cleaning them, combined with a new IVM.........she really goes now , also I replaced my motor mounts too........

When you gain access for this job, note that the center cabin air filter has 3 parts.
The outer tips of the cabin air filter plenum detach from the center.
It makes soooo much more room to wiggle the E-box lid out of the way.
