This proceedure should be standard maintenance for N52/N54s.

Hi there,

Recently did the charcoal delete and had MAF sensor cleaned as well. Noticed a little faster throttle response. No big sound difference either. Now, I really would like to clean my Vanos Solenoid only as maintenance procedure, I have no error codes or anything, my car is running smooth no issues here. Have anyone experienced a real difference after cleaning the these Solenoids? If so, I would like to know cuz i am about to do it after I clean my engine bay soon. My engine is N54 330i with 87k miles. Thanks in advance.
