I have a BMW 325i 2007 with N52B52 engine with 226k km

Last year I got my DISA Valve under the intake manifold replaced due to loss of power. Soon the car will be checked by the garage for the MOT

I decided to check for errorcodes with BMW INPA

I got the 2AAB code. Is it possible and logical that the other DISA valve is broken with this code? Or could it be the VANOS solenoid on the intake side? Exhaust VANOS solenoid is already replaced last year. Only symptom I have is sometime some irregular idle and sometimes the RPM hangs around 1200rpm before it drops to the idle RPM. And maybe some power loss in the lower RPM
