I have a e87 130i too and have the same problem. Its the valvetronic going bad. Its common on these engines i didnt replace mine yet cuz it goes away after restarting the car.

IF you read the fault memory IF one of your VANOS sensors was bad it would show a fault. When they really start to fail - you should also get an CEL too.


My bet is more on worn spark plugs or a vacuum leak. The valve cover or oil cap is a prime source to look at. Could be also things like carbon buildup or sludge inside of the DISA valve/intake tract.
