Next is to replace the VANOS solenoid and check if the error code come back again or not. If the fix did not get ride of the problem, I am considering trade in my 135 for something more reliable since I do not want to spend couple thousand dollars to open up the cylinder head to replace the sledge.
That's good mate. Replacing your solenoid will fix the issue, I'm sure of it. Vanos is a fairly common problem and fortunately a simple and cheap fix. Keep enjoying the 135i
