Got a P0112 code, has anyone dealt wiht this code before?

I got a P0112 code which is - Intake Air Temperature Circuit Low Input. Before I go changing my MAF.. can anyone make any suggestions? I cleaned the MAF with MAF cleaner, cleaned the connections and also, change the air filter. My car is a 2011 335D with 115K on it. Before I go to the dealer and buy a new MAF, I wonder if any of you had any experiences with this code? Thanks in advance!
