Pulled both bank 1 and 2 Vanos solenoids. Bank 1 solenoid is sloppy and has significant side to side play in the oiler area. Bank 2 solenoid is taught and has no side to side play in oiler. I am not sure if a normal vanos solenoid should have side to side play.

Should I replace the bank 1 solenoid? Based on the bank 2 check both are not equal. I really didnt want to go through swap and reassembly to lose more brand new coolant and I do not have the solenoid seals on hand.

Anyone with camshaft vanos control code resolved by a Vanos solenoid replacement?

I am beginning to think the worst that I need to tear down the motor and do the timing guides. To be honest there is no rattle or chain noises coming from the motor.
